Project Descripton 1.1 Project Background To speed up the urbanization of Linshui County, improve and establish a modern, comprehensive urban transportation system that is safe, convenient, efficient, clean and economical, and provide better educational and environmental conditions, Guang'an plans to apply for a loan from the World Bank to implement the “Guang’an City”. Bank loans medium-term adjustment program - the territorial waters of sub-item "(hereinafter referred to as" the project "), the project intends to draw on the Bank's advanced traffic management experience, strengthen urban traffic management, improve urban infrastructure in order to achieve the goals of sustainable urban development, Improve the livability level. The project consists of two parts, namely, the new Campus of Lingshui County Vocational Middle School in Economic Development Zone and the rehabilitation of roads and associated underground drainage network in Linshui Economic and Technical Development Zone (Linshui ETDZ). Among others, the newly established Economic Development Zone Campus of Linshui County Vocational Middle School covers an area of 44,430.41m2, with a total construction area of 40,194.72m 2 and designed for a total of 1,346 students. The campus will be built with a teaching building, a training building, a dormitory, a canteen and other ancillary facilities. The

4

project has an investment of 258.7223 million yuan. The road and drainage network rehabilitation project in Linshui involves four roads of Yulin Avenue (Feimu Road ~ Huancheng Road), Dafosi East Road (YuCheng Rd.~G210), Sanhe Road (Dafosi East Road ~ Jindexing Road), Zhongke Road (G210~ Yianda Avenue) with the total length about 6321m, the new rainwater pipeline of 5400m and the new sewage pipeline of 6900m. The project investment is 137.963 million yuan. Both projects will be sited within the Economic and Technological Development Zone of Linshui County, and the construction unit is Linshui County Yuanfeng Industrial Development Co., Ltd. According to the “Catalogue of Classified Management of Environmental Impact Assessment of Construction Projects”, the project should prepare an environmental impact report form. At the same time, according to the "Environmental Protection Law of the People's Republic of China", "Environmental Impact Assessment Law of the People's Republic of China" and other relevant laws and regulations, the construction unit entrusted our company to undertake the preparation of the environmental impact report form of the project. The evaluation will analyze and evaluate the environmental impact of the project construction based on engineering analysis and project characteristics and propose measures and recommendations to prevent and mitigate adverse impacts. At the same time, through the environmental impact assessment of the project, it provides a scientific basis for the environmental protection administrative department's environmental decision-making, environmental supervision and project environmental management. In addition, the EIA report form was also prepared in accordance with the World Bank’s safeguards policies.

1.2 Overall concept on Project EIA (1) The project involves road maintenance and school construction. The road maintenance is mainly to repair the damaged road pavement and to lay the rain and sewage pipelines, but involving no widening of existing roads and no increase of traffic flow after project implementation. At present, Linshui ETDZ is fully occupied by the enterprises. According to the monitoring results, the traffic volume basically reaches the design flow, and there are mainly factories and enterprises along the roads; the separate sewer system is not anticipated with discharge of pollutants into the environment during the operation period; therefore, the EIA will will focus on the impact assessment of the proposed school during operation; however, the impacts of road project on ambient air and acoustic environment during operation will not be predicted, instead, the monitoring results for this EIA will be used to explain the operational impacts of road project on ambient air and acoustic environment. (2) This medical office under the school project is only for colds, fever and trauma treatment, and only disposable medical equipment will be used without the generation of medical waste. The medical waste to be generated mainly includes disposable medical equipment, infectious waste such as waste cotton swabs and waste gauze used for trauma treatment, traumatic

5

medical waste such as disposable needles, and drug-induced medical waste such as expired drugs. Therefore, this EIA will not assess the impacts of medical wastewater, but only focus on the impacts of medical waste. (3) The experiments to be carried out in the training building of this school project are mainly physical tests on the service life, abrasion resistance and compression resistance of automotive parts and materials. No chemical experiment will be carried out, no chemical reagents will be used, and there will be no emission from the experiments.

1. 3 Necessity of project construction 1.3.1 Necessity of New ETDZ Campus for Linshui Vocational Middle School (1) Adapting to the needs of the development of vocational middle schools in Linshui County Linshui County Vocational Middle School is a nationally key vocational middle school, Sichuan Provincial Key Professional School, Sichuan Re-employment Training Base, Sichuan Provincial Labor Development Base, Sichuan Computer Rank Examination Test Center School, and established “National Vocational Skills Identification Station”. ". Existing vocational building area 39960 m2 (60 mu), the building area 54000 m 2 (including dormitory teacher). There are 212 faculty members, including 76 senior teachers, 51intermediate teachers, 81 professional teachers, and 66 "double- skilled" teachers. There are 65 teaching classes and 3,000 students in the school. The existing school building area can only accommodate more than 1600 people according to the medium vocational construction standards. At present, it has been seriously overloaded. The school has machinery (including machining technology, mold design and manufacturing, CNC technology applications, automotive applications and maintenance), information (including computer applications, computer network technology, computer animation technology), electronics (including electronic technology applications, Electrical and electrical applications), public affairs and art categories (including art, accounting computerization, garment production and production management) 4 major categories of 12 majors, of which mechanical processing technology is a provincial key specialty, electronic technology application is municipal Key specialty. It is equipped with four types of training rooms, including machinery, electronics, information technology, and finance. The training room is about 3,500 m 2 and the total value of equipment is 20 million yuan. According to the existing school building area, the vocational secondary education model from 2+1 to 2.5+0.5 and the need to adapt to the small class education, the current school building can only accommodate about 1,600 students at the same time, while the World Bank loan technical assistance sub-project The large-scale training equipment purchased has no space for resettlement in the existing campus, and the county vocational middle school urgently needs to expand to meet the needs of current social development. Due to the geographical environment of the existing campus, there is no expansion site in the surrounding area, and additional site

6

expansion is required. At present, it is urgent to have a place of about 1,400 people. The training of the Linshui County Vocational Middle School is divided into the actual training and factory training. The training factories are mostly located in the Linshui County Economic Development Zone. The existing campus is located in the mature old city area, far away from the Economic Development Zone. School-enterprise cooperation, considering the advantageous industries in the Economic Development Zone and the superior geographical location, the expansion of the site is inevitable. As the leader of vocational education in Linshui County, Linshui County Vocational Middle School is responsible for the development of vocational education. However, in view of the limited space of existing campus and the needs for production and education integration and school-enterprise cooperation, the new campus of Linshui County Vocational Middle School in the Economic Development Zone has been included in the agenda of the Linshui county government. (2) Supporting the construction of the economic development zone in Linshui County Vocational education is an important support for industrial development. The "13th Five-Year Plan for National Economic and Social Development of Linshui County" emphasizes the optimization of industrial space layout, pointing out that according to the concept of simultaneous industrial linkage, development needs and resource distribution, the three industries should be promoted in accordance with the concept of the three industries. The overall strategy of one core, two belts and three clusters. The plan emphasizes that different regions highlight different key industries and regional characteristics, optimize the spatial distribution of productivity development, and at the same time point out the general idea of industrial development of “industrial filing, agricultural efficiency improvement, and service quality improvement”. The optimization and upgrading of the industry requires a large amount of human resources as support and support. The new vocational and economic development zone will become a strong guarantee for the development of the adjacent aquatic industry and the supply and demand of human resources. Each year, the school can supply many technical and skillful personnel to the county Economic Development Zone. It is of great practical significance for the sustainable development of the company to attract investment from the Economic Development Zone. (3) Optimizing the needs of resource allocation in neighboring water education Vocational schools have the dual functions of academic education and short-term social training, highlighting the function of vocational education to serve the local economy. While vigorously developing academic education, according to market demand and social needs, we will face local economy and cultivate local talents; train export-oriented talents for the labor market; and cultivate rural practical technical talents for rural areas. Conduct diversified, multi-level and multi-type vocational skills training (employment training, poverty alleviation training, immigration training, re-employment training, labor transfer training, etc.). There are 106 primary and secondary schools in Linshui County (95 public and 6 private),

7

including 8 ordinary high schools, 7 vocational and technical schools (4 public offices, 3private schools), 34 primary schools, 24 junior high schools, and 9 There are 27 schools of special education and 1 special education school. 105 villages and teaching points. The county-run staff of more than 7,000 primary and secondary school students 11.5 million, of which 5.8 million students, 34,000 junior high school students, high school students 2.7million (of which 8 school where high school students 17,000 people). According to the requirements of 1:1 coordinated development, there will be 11,000 graduates from junior high school each year, of which more than 5,500 junior high school graduates are required to attend secondary vocational schools. Combined with the actual social status of the neighboring waters, the actual number of people who need to enter vocational schools each year is about 3,500. Existing four- run three private vocational schools, public vocational school has a state-level key (territorial waters vocational), vocational school three municipal key. There are 359 faculty members, 156 professional teachers (including 118 "double-skilled" teachers) and 203 culture teachers. Currently, the seven vocational middle schools have a total of over 9000 students with the annual enrollment of about 3,500 people, most of which (about 1,000 per year) are students for Linshui Vocational Middle School. Currently Linshui Vocational Middle School has a total of 3000 students; however, the existing campus only has the capacity to hold 1600 students and is already overloaded There is an urgent need to expand the school premises that can accommodate about 1,400 people. The adjacent professional schools in Linshui Vocational Middle School have 20 major categories of mechanical processing technology, accounting computerization, aviation services, etc. (including one provincial key specialty and three municipal key majors). Existing seven vocational campus covers an area of 93,800 m 2, the building area of 4.7124 Wan m 2, the total price of the device vocational school straight 14.46 million yuan. Each vocational school mainly cooperates with the county people's social bureau, the county agricultural bureau, the county party committee organization department and other county-level department training schools (points), facing enterprises, rural areas, communities, rural surplus labor, laid-off workers, transferred employees, returning farmers, urban and rural areas. New labor force, new farmers, retired soldiers and other personnel carried out special training and skill appraisal for rural labor transfer training, sunshine project, new professional farmer cultivation, rural practical technology, reemployment training, sewing, automobile application and maintenance, and fruit and vegetable flower production technology. Work, training about 0.6 million people per year. In addition to public schools, the three privately-run jobs are relatively remote in rural areas, the teaching environment is too poor, and the teaching staff is weak. Due to the scattered distribution of schools in 7 schools, most of the school's hardware facilities are backward, the training environment such as classrooms is poor, the teaching resources are uneven, the software facilities can't keep up with the pace of the times,

8

and the trend of the times is not synchronized with the growing development. The demand for social training functions has therefore continued to improve the current situation. Strengthening the construction of school districts, teachers, software and hardware facilities has become the top priority of the development of the job. Combined with the status quo, the government plans to change the characteristics of existing adult training scattered, chaotic, and inefficient, standardize social training, integrate the county's training resources, and decide to entrust some of the important vocational skills training tasks to the county. At present, due to various conditions of hardware and software, etc. in Linshui County, the social training function cannot be realized well, and the sub-project of technical assistance “development of training materials” cannot fully realize its benefits. To maximize the functions of vocational education, the new Economic Development Zone campus of Linshui County Vocational Middle School will provide both academic education and short-term training by making full use of available resources. Therefore, the new ETDZcampus for Linshui Vocational Middle School is an urgent need for the development of education in Linshui at this stage. (4) Implementing provincial and municipal policy decisions on vocational education The People's Government of Sichuan Province issued the "Implementation Opinions on Accelerating the Development of Modern Vocational Education" (Chongfufa [ 2014 ] No. 48), which clearly stated that "by 2020, we will adapt to market demand and promote economic upgrading in our province. Employment services, in-depth integration of production and education, the connection between vocational education and professional degree postgraduate training system, vocational education and general education, and Sichuan modern vocational education system embodying the concept of lifelong education." The Guang'an Municipal Party Committee and the Municipal Government attach great importance to vocational education, and clearly define the development of vocational education as an important part of the implementation of the “multi-point and multi-polar support strategy” in the city. It is required to continuously strengthen organizational leadership, establish a sound operational mechanism, and promote vocational education in our city. The scale has gradually expanded, and the ability to serve economic and social development has been continuously enhanced. "Guang'an Municipal People's Government's Implementation Opinions on Accelerating the Construction of a Modern Vocational Education System" (Guang'an Fufa [ 2015] No. 9) emphasizes the development goal of vocational education in Guang'an and develops modern vocational education with connotation and brand development.

1.3. 2 Necessity of Road and Drainage Network Rehabilitation in Linshui ETDZ (1) It is an urgent project to meet the needs of the recent development of industrial parks. The construction of the infrastructure project of the Linshui County Industrial Park in the Sichuan-Guangxi Cooperation (Guang'an) Demonstration Zone will not only provide basic material conditions for Guang'an Linshui County to undertake domestic and international

9

industrial transfer to accelerate economic and social development, but also support the central cities for the underdeveloped areas in the west. Accelerating scientific development and exploring new ways to provide demonstrations and lessons, but also exploring useful practices for coordinating urban and rural development and regional coordinated development of new models. The project construction is an inevitable choice to enhance the image of the demonstration area and enhance the effectiveness of investment promotion. However, the demonstration area is still in the growth stage of construction and development, and there are still gaps in terms of hard environment such as supportive infrastructure and comprehensive services support for production factors. At present, all levels of economic regions across the country have increased their opening up and external publicity, and the competition for foreign investment has been fierce. To gain a real place in the industrial transfer of developed coastal areas, and achieve substantial investment effectiveness, in addition to policy environment, industrial support, transportation and logistics conditions, labor costs, investors pay more attention to the comprehensive service level and comprehensive infrastructure of industrial parks. Therefore, in view of current development status of the demonstration area, attention must be paid to the improvements of hard environment, including the upgrading of infrastructure facilities and supportive public services in the ETDZ, the promotion of image for opening up. Enhance the attractiveness of foreign investors and enhance the investment confidence of foreign investors. This shows that the project construction is to meet the urgent needs of the industrial park in the short term. (2) The project is necessary for the county to proactively carry on the industry transfer from Chongqing Municipality. The "General Plan for the Construction of Sichuan-Chongqing Cooperation Demonstration Zone (Guang'an Area)" clearly states: the construction of the Linshui Electromechanical Industry Cooperation Park, the Wusheng Agricultural and Sideline Products Processing Cooperation Park, the Yuechi Pharmaceutical Industry Cooperation Park, and the Huaying Electronic Machinery Industry Cooperation Park, and actively undertake the industry. Transfer, build a docking Sichuan, Collaborative supporting industrial base. The construction of this project has made the infrastructure of the Linshui ETDZ more perfect. It is the initiative to accept the industrial transfer of the Chongqing main city and the Liangjiang New District. Functional extension, factor spillover and civilized radiation, build a half-hour traffic circle and economic circle that seamlessly connect with Chongqing and highly integrate, and promote the development of industrialized urbanization. (3) The project is needed to adapt to the growing traffic volume in Linshui ETDZ. Linshui ETDZ is in the south of Linshui County. It is the only way connecting the old downtown, and new urban area in the west with Chongqing. According to "Linshui City Master Plan," planning in the territorial waters surrounding the industrial park adjacent to the construction of three motorway exit, respectively, Shanghai-Chengdu Expressway West exit territorial waters, territorial waters east Shanghai-Chengdu Expressway exit, including Mao high-speed

10

section of Chongqing territorial waters south exit, where the Shanghai-Chengdu Expressway West exit territorial waters, including Mao Chongqing high-speed segment of the territorial waters of the South export has been opened to traffic. With the completion of the expressway exit, the traffic flow through the neighboring water to Chongqing will increase greatly, and the traffic volume of the industrial park will increase exponentially. The construction of this project will improve the traffic conditions of the adjacent water industrial park and meet the growing traffic demand. (4) The project is needed to complete and upgrade the urban road traffic network. The existing roads in Linshui ETDZ are concentrated in the northeast of the industrial park. With the approval of the “Overall Plan for the Construction of the Sichuan-Chongqing Cooperation Demonstration Zone (Guangan Area)”, the number of enterprises entering the Linshui ETDZ has increased significantly, and the industrial park has built a plot of land. It is far from meeting the requirements. Therefore, the southern part of the industrial park has become the focus of the next development. The West Ring Road of Linshui ETDZ is the main passage connecting the Shanghai-Chengdu Expressway and the Baomao Expressway (Chongqing Section). Rucheng Avenue is the main passage connecting the old downtown of Linshui and the Dayu Expressway. The Rucheng Avenue and the Dayu Expressway have been completed. The four roads, such as Yulin Avenue, to be built under this project are important passages connecting the Linshui ETDZ and the West New City of Linshui County and are the main composition of the road network in the southern part of the ETDZ. In summary, the roads will complete and bring significant improvements to the urban road network, improve the traffic conditions of residents along the road, and improve the traffic organization of the entire road network. (5) It is an urgent need to improve the living environment of industrial park residents and reduce environmental pollution. The Linshui ETDZ and the Old Town of Linshui are separated by the Hurong Expressway. The sewage from the industrial park cannot be collected to the first sewage treatment plant in Linshui County. The terrain of the entire industrial park is high in the middle and low in the north and south. According to the “Controlled Detailed Planning of the Interactive Demonstration Zone in the Southern City of Linshui County”, two new sewage treatment plants are planned to be built in the north and south of the industrial park. If the sewage in the industrial park is discharged into the Shiba River without treatment, it will inevitably cause serious pollution to the Shiba River. The project will build a new sewage pipeline along the road and collect the sewage into the proposed second sewage treatment plant of Linshui County, which will greatly improve the environment of the industrial park and reduce the pollution to the Shiba River. To sum up, the project is to develop local vocational education level and provide professional skills for the region; at the same time reduce pollution, improve urban water quality environment,

11

improve the life quality of local residents, safeguard the health of the downstream people, and promote social comprehensiveness. Development, the construction of this project is very necessary and urgent.

1.4 Compliance with industrial policies and related plans 1.4.1 Compliance with industrial policies The project involves road reconstruction, school construction and rainwater and sewage network. Among others, the road and drainage rehabilitation project is classified as urban infrastructure project, which is part of the encouraged category “XXII, urban infrastructure '9, urban water supply and drainage, water supply and water treatment plant project” as defined in the “Guiding Directory of Industrial Structural Adjustment (2011 version and 2013 revision)” and is in line with relevant national industrial policies. The Linshui Vocational ETDZ campus School project is classified as the encouraged category of “(3) Vocational Education in 36. Education, Culture, Health, and Sports Services” in the “Industrial Structural Adjustment Guiding Catalogue (2011) and (2013 Revision)”. It is in line with relevant national industrial policies. In summary, the project is complaint with relevant industrial policy requirements.

1.4.2 Compliance with relevant plans and policies The project is in Linshui ETDZ. The relevant planning related to the project includes “Landscape Project of Linshui County”, “13th Five-Year Plan of Linshui County (2013- 2020)” and “Traffic of Linshui County” "Development Plan", "Controlled Detailed Planning of Linshui County Economic Development Zone" and "Controlled Detailed Planning of Linshui County". The above plan particularly emphasizes the improvement of urban and rural infrastructure systems and the creation of a livable environment. The project construction will not only improve the transportation infrastructure of Linshui County, the efficiency of sewage wastewater collection in Linshui ETDZ, but also improve the regional education facilities, which provides a good response to relevant plans and requirements of the State, Sichuan Province, Guang'an Municipality and Linshui County with the compliance with relevant policies.

Near the project area is an urban development zone. The surrounding infrastructure construction is relatively complete, and water, electricity, communication and other facilities are easily accessible, which can fully meet the needs of road construction. There are no current houses, cultural relics, lakes, etc. within the red line of the project planning land acquisition. This project does not set up quarries and borrow pits. All the stones and sand materials used are purchased from Linshui County and surrounding counties. The steel, cement, wood and water required for the project can be solved in Linshui County, and the quality and quantity can meet the requirements of road construction. All the construction of the project uses purchased concrete, and the project itself does not have a concrete mixing yard. The project area is adjacent to the completed municipal road, and the internal and external traffic is very convenient, and the construction conditions are good. The project materials and earth and stone transportation mainly use the above road sections.

1.6.5 Road maintenance and disease remediation plan As the project is in the road improvement project, the plan maintains the flat and vertical lines of the original road. In view of the characteristics of the old road reconstruction, combined with the experience of the rectification of trunk roads in the districts and counties under the jurisdiction of Guang'an City, this project repeatedly considers the material selection of the road surface layer to extend the service life of the road to improve the safety and comfort of driving. This section uses SMA asphalt concrete pavement. (1) single crack For a single vertical and horizontal crack, no joints have been developed and no muddy or subsidence has occurred. The slotting machine is used to expand the joint and then fill with special joint filler. The slotting machine should have the function of automatically tracking cracks. When the slit width is less than 13 mm, the seam depth should be 15 mm, and when the slit width is greater than 13 mm, the seam depth should be 20 mm. The joint filler is made of hot- melt high-molecular polymer sealant. The crack is poured before the addition. It requires strong

40

adhesion and adhesion, and the climate change can maintain good ductility and high elasticity.

Figure 1.6 -1 Single crack treatment plan (2) Developed longitudinal and transverse cracks and slight block cracks 1 For the sections that have developed longitudinal and transverse cracks and slight block cracks of the joints, and the road surface has obvious loose damage, firstly, the original road surface layer is milled, and the base layer is not loosely damaged, and the surface of the original road surface is dirty. And the loose particles are thoroughly cleaned, and the adhesive layer oil is evenly spread. Finally, the medium-grain asphalt concrete AC -20C is used for repair; if the base layer is cracked, the 0.5m wide fiberglass grid should be symmetrically placed on the crack at the top surface of the base layer; If the base layer has been loosely damaged or has muddy or subsidence, the original pavement should be excavated and repaired with cement stabilized gravel. The compacted gravel is required to be compacted by a roller, and the roller cannot be operated on an area that is too small. The manual compaction method is adopted to ensure that the compaction degree meets the specification requirements. When milling the original asphalt concrete pavement surface layer, each side needs to be over-milled by not less than 25cm, and the modified emulsified asphalt adhesive layer oil is evenly distributed after the completion of the health, and the base layer is topped. The surface crack is symmetrically placed on the 0.5m wide fiberglass grid, and finally the medium grain asphalt concrete AC- 20C is used to repair the original asphalt surface layer. 2 For the longitudinal and transverse cracks and slight block cracks that have developed the joints, but the road surface does not appear obvious loose road sections, first remove the original road surface layer, and then thoroughly clean the top surface of the original road surface dirt and loose particles. Then, the 0.5m wide fiberglass grid was symmetrically placed at the crack location, and the modified emulsified asphalt adhesive layer oil was evenly sprinkled. Finally, the medium granular asphalt concrete AC- 20C was used for repair.

The proposed project of the newly built Economic Development Zone Middle School project is in the planned educational land. Requisition of the net. The road and drainage network rehabilitation project in the Economic Development Zone is the construction of the technical renovation project, mainly for the repair of damaged roads and the construction of rainwater and sewage diversion pipes along existing roads. (1) Basic conditions of the original road This project involves the overhaul of the road Yu neighbor Avenue, Big Buddha Temple Road,

45

Sanhe Road and Branch Road are in Linshui County Economic and Technological Development Zone, at the end of 2006 are completed. With the rapid economic development of Linshui County in recent years, the increase of traffic volume and the crushing of over-loaded vehicles, various diseases have appeared on the road surface, and ruts and potholes have caused great safety hazards to vehicles and pedestrians. The transformation is imminent. 1 original roadbed and pavement This project is the reconstruction of the old road, and it is necessary to carry out the rain and sewage diversion and rectification of the underground pipe network. The original road is seriously damaged, and the current road inspection report cannot be collected. When the road is reconstructed, the rainwater pipeline should be diverted. It is necessary to break the existing road surface and consider the width of the existing roadway and the excavation of the pipeline. The remaining roads are extremely small in width and have low road utilization. Considering the uniformity of the road pavement upgrade and transformation, this time the roadway is destroyed. After designing the existing roads to the design elevation, after the rainwater and sewage diversion pipelines are implemented to refill the trenches to the top surface of the roadbed, the pavement structural layer is uniformly paved. 2 original road surface disease The pavement structure of the project section is: 3cm fine grain asphalt concrete AC-13I upper layer + 4cm medium grain asphalt concrete AC-16I lower layer + 20cm cement stabilized macadam base layer + 20cm cement stabilized macadam base layer + 17cm grade Stone leveling. After several years of operation, different degrees of disease have appeared on the road surface. Pavement disease manifestations are mainly: irregular cracks, lateral cracks, longitudinal cracks, cracks, mud, subsidence, looseness, rutting, subgrade subsidence. The pavement conditions of Dafosi East Road is the poorest. The existing diseases have seriously affected the comfort and safety of driving. There are serious safety hazards to passing vehicles and pedestrians. 3 original road disease analysis The main reasons for the current road conditions are as follows: 1) The continuous increase of traffic volume, the increase of over-limit overloaded vehicles, the existing cement pavement cannot meet the load requirements; 2) The combination of the lower layers on the road surface is poor, and the durability of the cement mixture is poor. Under the repeated action of the driving load, the surface layer of the road surface is fatigue-damaged; 3) The water-stable base layer is characterized by brittleness, strong sensitivity to temperature and humidity, and easy to be affected by water. The water-stable base layer generates excessive cracks and causes reflective cracks on the asphalt pavement. 4) There are construction defects in the joint of the water-stable layer in the middle seam, and the original water stabilizes the material grade with poor coordination and partial looseness.

46

5) The road surface water is not infiltrated into the pavement structure in time. The road surface water gradually penetrates the pavement structure. Under the repeated action of the traffic load, the road surface gradually appears muddy, subsidence, loose, pit and other diseases.

中科路现状 4 Currently, there are mainly environmental problems that need to be overhauled. 1) The road surface is damaged or there is no road surface engineering, which causes dust to fly and affects the atmospheric environment; 2) the road surface is uneven and causes noise; 3) Imperfect drainage facilities, or no drainage engineering and protection works, have an impact on soil and water conservation along the line. (2) Problems with road pipelines in the economic development zone At present, most of the road drainage systems in the Economic Development Zone are rain and sewage flow systems. Most of them use dark trenches or confluence pipelines. The drainage is rather messy, and the rain and sewage are discharged nearby. The pollution of the river water is large. The main problems of the current drainage are: 1 Domestic sewage and some industrial wastewater are simply treated by biogas tanks and septic tanks, but they are discharged into water bodies without further treatment, causing a certain degree of pollution to natural water bodies, especially to the downstream Yulin River. 2 Urban drainage facilities have too many debts, narrow ditch, long-term disrepair, serious collapse and blockage, poor drainage, sewage overflow during the flood period, affecting the urban environment and residents' lives. 3 The new drainage pipelines on various roads lack systematic considerations and need to be further coordinated to avoid future conflicts in the elevation. Through the construction of the sewage main pipe and sewage treatment plant of this project, all domestic sewage in the regional area will be included in the sewage main pipe, and finally discharged into the sewage treatment plant for centralized discharge and discharge, which can greatly improve the water quality of the regional surface water body. (3) Basic conditions of school construction projects The school construction project is a new construction project. The proposed construction site is in the planned educational land and is currently a requisitioned net land. The original plot is agricultural land. At present, the crops in the plot have been harvested and cleaned, and there are no remaining environmental problems related to the project.

Engineering Analysis Table (6) This project is a non-productive project. The implementation of this project is mainly divided into construction period and operation period. 6.1 Process 6.1.1 school construction Economic Development Zone school construction project plan is broadly divided into five steps: site preparation, foundation construction, structure construction, equipment installation, architectural features, built and put into use until later. The process flow during the construction period is shown in Figure 6.1-1.

FIG. 6.1 -1 construction of the proposed project workflow diagram of link and induced pollution 6.1.2 road reconstruction The project is intended to renovate the road surface, mainly the road surface demolition and reconstruction. This evaluation focuses on the project construction and construction process. The process consists of project planning and design, on-site reconnaissance, program optimization, construction planning, construction preparation (construction materials, construction equipment), and engineering construction. The process flow and pollution production are described. Figure 6.1 - 2. The analysis block diagram of the process flow is as follows:

Figure 6.1 - 2 Road reconstruction engineering process flow chart 6.1.3 rain and sewage pipe network construction This project uses artificial trenching trenches. Pipe trench excavation is strictly carried out in accordance with relevant standards. The depth of the trunk line is according to the pipe top to the ground: the road crossing is ≥1.2 m, the ditch is ≥0.6 m ; the safety distance from the residential

71

building is ≥5 m ; the optical cable is ≥0.5 m ; the trench is excavated and grading The coefficient is 0.3. Before the trench was cleaned, the bottom of the trench was cleaned and the bottom of the trench was removed, and the bottom of the trench was backfilled with 200 mm thick soft soil. The lower ditch of the pipe adopts a manual lower ditch. The pipeline is backfilled and divided into two. Fill back the soft soil for the first time, 300mm above the top of the tube, and lay a warning tape; the second time backfill other soil. The surface layer is backfilled with cultivated soil, and the backfill is 300mm above the natural ground. For crossing roads (the road pipeline project of this project does not involve crossing the expressway), a seamless steel casing is used to pass through the buried pipe, and the distance from the top of the buried pipe is not less than 1.2m. Excavation methods are used. After the pipeline was installed, the road was backfilled, compacted and hardened, and the road surface was restored. The construction of sewage pipe network of this project adopts segmentation type, and the combination of machine operation and manual operation.Rain and sewage diversion pipeline project each production process and pollution links Figure 6.1 3.

Figure 6.1 3 Pipeline construction process flow and schematic diagram of pollution 6. 2 Main pollution sources and control measures during the construction period 6. 2.1 Construction of the main school building project the main source of strength and control measures (1) Air pollutants During the construction period, the air pollution mainly comes from the transportation and stacking of building materials (cement, sand, stone); earthwork filling and on-site stacking; concrete mixing; stacking and cleaning of construction materials; transportation vehicles during construction period. 1 mechanical equipment exhaust Equipment main exhaust gas containing SO 2 and NO x emissions Watian site during construction activities, such as the types of fuel transport power machinery. Since the construction of fuel-powered machinery is indirect operation and the amount of use is small, the emitted fuel-gas pollutants will have a discontinuous impact on the air quality at the construction site. Since the fuel used by the construction workers is prohibited from using coal, the clean energy liquefied gas is used, and the pollution caused by combustion is small and negligible. 2 dust The construction dust mainly comes from the on-site handling and stacking dust generated by construction materials (cement, sand, stone, etc.); the dust generated by the cleaning and stacking of construction waste; the backfilling of trenches; the road dust caused by people coming to the road. Construction of TSP pollution mainly produced in foundation

72

excavation, transport raw materials, the use of cement and other operations. The analogy method was adopted to select the measured results of the Chengyu Expressway, which was also built in the hilly area, for comparative analysis. In the case of clear weather and no sprinkling on the construction site, when the earthwork loading, unloading, transportation and on-site construction work were carried out, the downwind direction (wind speed) 2.4m / s) The concentration of TSP (mainly sand dust) in the range of 50 ~ 150m canreach 5.0 ~ 19.7mg / m 3, when the lime soil loading, unloading, transportation and mixing operations, in the downwind direction (wind speed 1.2m / s) 50 ~ 150m The range TSPconcentration can reach 0.8-9.0mg/m 3, which indicates that the TSP pollution of the ambient air in the evaluation range is serious. The project is located in the urban planning and construction, and it is necessary to suppress the impact of building dust on the atmospheric environment. According to the document of the Sichuan Provincial People's Government (Chongfu Fa [ 2014 ] No. 4), the third key task in the Sichuan Province Air Pollution Prevention and Control Action Plan 4 to strengthen the construction site and road dust pollution remediation. Strict construction of construction site dust environment management, active implementation of green construction, construction site must be completely closed to set up retaining walls, open operation is strictly prohibited, construction site roads, operation areas, living areas must be hardened; development, improvement and strict implementation of construction management Institutions, comprehensive implementation of on- site standardization management, the city's main urban construction site to achieve "six must" (must must cover operations, must harden roads, must set up flushing facilities, must be sprinkled in time, must implement cleaning personnel, must regularly clean the construction site), "Six is not allowed" (No vehicles are allowed to take out the mud, no slag-loading vehicles are allowed to load the top, no construction waste is allowed to be thrown at high altitude, concrete is not allowed to be mixed on site, water is not allowed on the site, and waste is not allowed to be burned on site). The following measures must be taken to suppress dust : 1) The entrance and exit of the construction site must be hardened; in the site, the construction road is paved with mats or other spacers to prevent the tires from being contaminated with a large amount of soil. 2) The roads for import and export are frequently washed to keep the road clean; in the dry season, some construction areas and roads are properly sprinkled with water to reduce dust; 3) Clear the soil and dirt of the transport vehicle in time. 4) Clear the road dust in time. Once the transport vehicle sprinkles the spoil and slag, it must be organized to clean and keep the road clean. It is strictly forbidden to transport the spoil and waste slag in rainy days to prevent the spoil and waste from being directly brought into the surface river by rain. 5) The main body of the building is covered with a dense mesh safety net. 6) The building materials and the construction and transportation vehicles are sealed to prevent

73

the materials from being scattered along the way. 7) Vegetation protection measures: A, taken sealed off construction, construction dust falling preventing leaves nearby vegetation. B, transport routes and yard, residue field, earthworks etc. temporary yard away from the building to the surrounding forest, through which the absolute prohibition; regular trees road transport in the past were watering flushing. After taking the above measures, it is still impossible to completely solve the problem of dust emissions, especially sporadic unorganized emissions. The construction unit shall carry out environmental protection education and work for the construction workers, and civilized construction. (2) sewage During the construction period, the wastewater generated includes the production wastewater and the domestic wastewater of the construction personnel. 1 domestic wastewater The project of school construction engineering construction workers mainly domestic sewage generated in construction camps, construction workers when the peak of about 100people, according to 10 0L / person ▪ d is calculated, sewage generated by the coefficient 0.85 dollars, the amount of domestic sewage About 8.50 m 3 /d, the amount of domestic sewage generated during the construction period is 6 120 t. The contaminant concentration in the effluent construction camp life values: SS300mg / L, COD3 5 0mg / L, animal and vegetable oils 3 0mg / L, NH 3 -N 35 m g / L. The EIA requires the temporary storage pool in the construction camp to collect the domestic sewage from the construction camp and use the municipal suction truck to transport it to the sewage treatment plant for disposal. This will ensure that the domestic sewage will be effectively treated during the construction period, and the domestic sewage will not be discharged. Water body. 2 construction wastewater During the construction period of the project, machine maintenance and vehicle flushing are involved in the construction camp. A small amount of mechanical maintenance and cleaning wastewater and car wash wastewater will be generated. The oil-resistant grit chamber near the machine repair site and the car wash site will be located in the construction camp. The main pollutants of this part of the wastewater are S S (1200mg / l) and petroleum (2 0mg / l), treatment scale 1 0m 3 / d, the treated effluent washing water for back and watering space dust, to avoid pollution of the environment outside the waste water discharge. At the same time, the management and maintenance of fuel machinery and vehicles will be strengthened to effectively reduce the phenomenon of running, running, leaking and dripping, thereby reducing the amount of oily sewage generated. This project mainly uses commercial concrete, does not produce a large amount of concrete mixing wastewater and sand and gravel washing wastewater. A small amount of wastewater can

74

be set up around the construction site, and the wastewater will be collected and reused in the sedimentation tank for reuse. Spray control dust, construction wastewater is strictly prohibited. (3) noise During the construction period of the school construction project, there are many types of working machinery. The noise during the construction period comes from construction machinery operation and automobile transportation in construction activities such as construction excavation and concrete mixing. According to the engineering analogy analysis, the main noise sources to be controlled are concrete mixers, excavators and other equipment, and the noise level is above 80dB. The operation of the construction machinery and the transportation of the transportation vehicles will have a certain impact on the acoustic environment around the construction area. According to the analysis of the analogy of similar projects, road construction, operation noise value of the device in the following table 1 6.2. 6.2 Table 1 List of equipment and machinery noise Distance from measuring Serial Mechanical Maximum sound model point to construction machine number type level dB(A) (m) hydraulic 1 W4-60C 5 90 excavator 2 Loader ZL40 type 5 87 3 Rock drill ZY-24 5 85 4 Air compressor L2-10/8 5 98 5 Tower crane 5 84 6 Vibrating rod 5 98 7 Truck 10t 5 75 As the project construction will have a certain impact on the surrounding environment. Therefore, the EIA requires: 1 Establish a sound management system 1) The construction unit shall report to the local Environmental Protection Bureau 15 days before the start of construction to explain the construction project, the site, the noise intensity that may be emitted and the noise prevention measures taken. After obtaining the approval of the Environmental Protection Bureau, the construction unit will post the “ Anmin Notice ”. The name of the project, the construction content and time, the contact information of the project owner, the name of the construction unit, the person in charge of the construction site and the contact information, possible noise pollution and the prevention measures taken as the publicity content. At the same time, it actively contacts the environmentally sensitive points around the plot and establishes a good relationship of mutual understanding and mutual support. 2) During construction, the masses visit the reception station at the construction site, which is

75

responsible for preventing the adverse effects of construction disturbances and people's disturbances on the normal construction progress of the project, and avoiding or reducing the occurrence of disturbing people or people. Regularly carry out civilized construction education for construction workers, advocate civilized construction, and enhance the self-conscious awareness of all construction workers. 2 Construction site anti-noise control 1) Control of artificial noise. The construction site advocates civilized construction, establishes and improves the management system for controlling man-made noise, minimizes artificial loud noises, and enhances the self-conscious awareness of all construction workers against noise and disturbance. 2) Control of noise operation time. Night (22: 00- 6:00 the next day) prohibit the construction work, daytime 12:00 -14 points prohibited the construction of high noise equipment. If it is necessary to carry out nighttime construction work due to special needs, the construction unit shall submit the application in accordance with the relevant laws and regulations on the 4th day before thenight construction. The construction unit shall announce the nearby residents on the construction site one day before the night construction. 3) Reasonable use of construction machinery. Construction machinery and transportation vehicles are the main causes of construction noise. To reduce the impact of noise during construction period on sensitive surrounding areas, the construction unit should use advanced construction machinery and technology during the construction process, select low-noise operation equipment, and ban the use of countries. The mechanical equipment that has been eliminated is clearly arranged according to the site conditions; the muffler is installed in the medium and high frequency noise sources such as air compressors and fans. 4) Reasonably arrange construction tools. Construction units rational arrangement of construction equipment during construction, steel reinforced high-noise sound processing facilities set up in the processing room. After the initial completion of the underground project, the small equipment such as air compressors will be moved to the underground project under the premise of safe construction to reduce the impact of construction noise on the surrounding environment. 5) Actively improve production technology. The production operations should be developed as far as possible to the outside, and the amount of construction work and the contents of the work should be constructed. With commercial concrete, it is strictly forbidden to use equipment such as concrete mixers that produce continuous noise. 3 Transportation Management The transportation of vehicles should reasonably plan the transportation routes. When transporting vehicles through urban roads, it is forbidden to whistle and control the speed of the vehicles. At the same time, the transportation period should avoid the peak of residents' travel

76

and rest periods. Seriously implement noise prevention measures to achieve civilized construction, which can minimize noise disturbance during construction; with the end of the construction period, construction noise will disappear. After the above prevention and control measures, the noise of this project can achieve the discharge standard. (4) Solid waste The solid waste in the construction period of the school construction project of the project mainly comes from earth and stone works and concrete pouring to produce waste slag, construction waste, and domestic garbage of construction workers. The school construction site belongs to the mountain bag, which is all excavated. The process of building the school of earth excavated volume of 6 00 000 m 3, in which the excavation 3 60 000 m 3, digging stonework 2 40 000 m 3, the amount of topsoil excavation Fang 1 1100 m 3 (to dig topsoil 2 5 cm Count). The topsoil is transported back to the green belts in other construction areas around the project. The earthwork is transported back to other low- lying areas around the project, and the stone-selling stone factory is crushed and sold. The amount of daily garbage produced by construction workers is 0.5kg / d., and the construction of the school takes 24 months. School construction project staff of about 100 people,produces the largest amount of construction garbage was 50 kg / d, construction garbage produced a total of 88.80t. The evaluation reference Luoyang City Construction Committee "on the issuance of" Luoyang City construction waste calculation standard "notice" (Luo Jian [2008] No. 232), from construction of reinforced concrete structure housing the main construction waste by 0.03 t / m 2 meter, The construction area of the school construction project is 40,194.72 m 2, andthe construction waste slag generated during the construction of the project school is about 1205.84 t, which is transported by the construction party to the construction landfill designated by the local department, and the adverse impact is small. 6. 2.2 road maintenance and sewer network construction phase comprehensive renovation project mainly the main source of strength and control measures (1) Air pollutants Road maintenance and sewer network construction Comprehensive Treatment of ambient air pollution comes mainly from construction materials (cement, sand, gravel) handling and stacking, stacking and cleaning, trench backfilling and construction of transport vehicles run construction materials and other operations Dust caused by the process, pavement mechanical equipment exhaust and asphalt smoke. 1 mechanical equipment exhaust Equipment main exhaust gas containing SO 2 and NO x emissions Watian site during construction activities, such as the types of fuel transport power machinery. Since the construction machine is an indirect fuel power operations, and the amount is not much, thus

77

producing intermittent air quality have a construction point fuel exhaust emission of pollutants. 2 dust The construction dust mainly comes from the on-site handling and stacking dust generated by construction materials (cement, sand, stone, etc.); the dust generated by the cleaning and stacking of construction waste; the backfilling of trenches; the road dust caused by people coming to the road. During the construction period, TSP pollution mainly occurs in the operations of foundation excavation, raw material transportation and cement use. The project is located in the urban planning and construction, and it is necessary to suppress the impact of building dust on the atmospheric environment, animals and plants. According to the document of the Sichuan Provincial People's Government (Chongfu Fa [2014 ] No. 4), the third key task in the Sichuan Province Air Pollution Prevention and Control Action Plan 4 to strengthen the construction site and road dust pollution remediation. Strict construction of construction site dust environment management, active implementation of green construction, construction site is strictly prohibited open operation ; development, improvement and strict implementation of construction management system, full implementation of on-site standardization management, urban main urban site to achieve "six must" (must Enclosure work, road must be hardened, flushing facilities must be set up, watering must be carried out in time, cleaning personnel must be implemented, construction site must be cleaned regularly), “six is not allowed” (no vehicles are allowed to go out with mud, no dumping is allowed to load Do not throw construction waste at high altitude, do not allow concrete to be mixed on site, do not allow water to accumulate on the site, and do not allow on-site incineration of waste). The evaluation requires the construction unit to take the following dust control measures during the construction process : 1) Before the road surface is broken, it is necessary to remove the dust on the road surface. In the process of dismantling, the spray device is installed to spray and suppress the dust in the working area. 2) Once the transport vehicle sprinkles spoil and slag, it must be organized to clean and keep the road clean; it is strictly forbidden to transport spoil and slag in rainy days to prevent spoil and slag from being directly brought into the surface river by rain. 3) The building materials and the construction and transportation vehicles are sealed to prevent the materials from being scattered along the way. 4) The transportation passages and material yards, the slag yards, the earthwork temporary storage yards, etc. are all away from the forests around the construction site, and it is absolutely forbidden to cross them; the street trees that transport the passing roads are regularly sprinkled with water. After taking the above measures, it is still impossible to completely solve the problem of dust emissions, especially sporadic unorganized emissions. The construction unit shall carry out environmental protection education and work for the construction workers, and civilized

construction. 3 asphalt smoke The road maintenance project uses asphalt concrete pavement. The base layer concrete of this project comes from the commercial warehousing. The asphalt used in the SMA asphalt pavement is directly purchased from the municipal asphalt plant. The asphalt tamping is prohibited on the site. During the pavement construction phase, a small amount of asphalt smoke is generated during the pavement laying process. The paving time is short, and the asphalt smoke generated during the paving process is extremely small, which has little impact on the local environment. (2) sewage During the construction period, the wastewater generated includes the production wastewater and the domestic wastewater of the construction personnel. 1 domestic wastewater The project road maintenance section construction, when the peak of construction workers about 80 people, road maintenance construction site work camps without facilities, no site canteen and dormitory construction site, so the construction of waste water and domestic sewage is mainly produced by construction workers press 1 0L / person ▪ d calculationcoefficients generated by sewage 0.85 meter, domestic sewage is about 0.68 m 3 / d, the amount of the construction of domestic sewage process 1 22.40 m 3. Concentration values ofdomestic sewage pollutants in road construction projects are: SS 3 00 mg / L, COD 35 0 mg / L, NH 3 - N 35 m g / L. Road maintenance project is located in the territorial waters of urban built-up areas, improve the surrounding community service facilities, sewage municipal facilities have been built relying on the surrounding treatment discharge standards, to avoid sewage discharge standards do not contaminate surface water.

2 construction wastewater Construction site wastewater is concrete curing wastewater, construction machine flushing water and pipeline test water drainage. The following treatment measures must be takenfor construction wastewater during construction period : 1) The project mainly uses commercial concrete, which will not produce a large amount of concrete mixing wastewater and gravel material washing wastewater. A small amount of wastewater can be provided with drainage ditch around the construction site, and the site wastewater is collected and reused after being treated by sedimentation tanks. Spraying dust control at the construction site, construction wastewater is strictly prohibited from being discharged. 2) Set up drainage ditch on both sides of the road construction, and build a small grit chamber at a certain distance and at a low level in the section: as a concrete maintenance wastewater collection and treatment facility, all the treated wastewater after sedimentation is reused for pavement For concrete maintenance, the submerged pump is used to pump the supernatant

79

regularly or irregularly, and the grit chamber is cleaned regularly. 3) After the pipeline is laid, test water drainage is required. The test water is cleaned with tap water, and the water is drained into the rainwater pipeline after the test. (3) noise During the road maintenance and construction period, there are many types of working machinery. The noise during the construction period comes from construction machinery operation and automobile transportation in construction activities such as construction excavation and pavement laying. According to the engineering analogy analysis, the main noise sources that need to be controlled are pavers, loaders, drilling rigs, excavators and other equipment, and the noise level is above 80dB. The operation of the construction machinery and the transportation of the transportation vehicles will have a certain impact on the acoustic environment around the construction area. According to the analysis of the analogy of similar projects, road construction, operation noise value of the device in the following table 2 6.2. Table 6.2- 2 Noise list mechanical equipment Distance from measuring Serial Mechanical Maximum sound model point to construction machine number type level dB(A) (m) 1 Loader ZL40 type 5 90 2 Vibratory roller YZJ10B 5 86 3 Tire roller ZL16 type 5 80 4 Rock drill ZY-24 1 90 5 Air compressor L2-10/8 1 88 6 Pavers VOGELE 5 80 7 Vibrating rod 1 85 8 Truck 10t 7.5 75 As the project construction will have a certain impact on the surrounding environment. Therefore, the EIA requires: 1 Establish a sound management system 1) The construction unit shall report to the local Environmental Protection Bureau 15 days before the start of construction, indicating the construction project, the site, the noise intensity that may be emitted, and the noise prevention measures taken. After approval by the Environmental Protection Agency, the construction unit will post it around the construction area. " Anmin notice ", the project name, construction content and time, project owner contact information, construction unit name, site manager and contact information, possible noise pollution and prevention measures taken as public announcements. At the same time, it actively contacts the environmentally sensitive points around the plot and establishes a good relationship of mutual understanding and mutual support.

80

2) During construction, the masses visit the reception station at the construction site, which is responsible for preventing the adverse effects of construction disturbances and people's disturbances on the normal construction progress of the project, and avoiding or reducing the occurrence of disturbing people or people. Regularly carry out civilized construction education for construction workers, advocate civilized construction, and enhance the self-conscious awareness of all construction workers. 2 Construction site anti-noise control 1) Control of noise operation time. Night (22: 00- 6:00 the next day) prohibit the construction work, daytime 12:00 -14 points prohibited the construction of high noise equipment. If it is necessary to carry out nighttime construction work due to special needs, the construction unit shall submit the application in accordance with the relevant laws and regulations on the 4th day before the night construction. The construction unit shall announce the nearby residents on the construction site one day before the night construction. 2) Reasonable use of construction machinery. Construction machinery and transportation vehicles are the main causes of construction noise. To reduce the impact of noise during construction period on sensitive surrounding areas, the construction unit should use advanced construction machinery and technology during the construction process, select low-noise operation equipment, and ban the use of countries. The mechanical equipment that has been eliminated is clearly arranged according to the site conditions; the muffler is installed in the medium and high frequency noise sources such as air compressors and fans. The construction unit conscientiously implements noise prevention measures to achieve civilized construction, which can minimize noise disturbance during construction; with the end of the construction period, construction noise will disappear. After the above prevention and control measures, the noise of this project can achieve the discharge standard. (4) Solid waste The solid waste during the construction period of the proposed project is mainly from the construction waste slag, the earthwork and concrete pouring, the waste slag generated in the stone masonry, the construction waste, and the domestic garbage of the construction workers. According to the statistical results, the road maintenance project broke the waste concrete block produced on the road surface by about 9 1557 m 3, and all the concrete blocks were sold to the waste stone processing factory and sold as stone materials after crushing. Sludge sewer network construction of the original pipeline process produces mainly dredging silt, clean-up and other plastic waste, which part of the amount of generated sludge 5.00 t, the amount of waste generated is 1.00 t, and the sludge after drying The garbage is disposed of by the sanitation. The amount of daily garbage produced by construction workers is 0.5kg / d ▪ person, the project road overhaul and rain and sewage diversion pipe network project

81

takes 6 months. The construction of roads and rainwater and sewage diversion pipe network is about 80 people. The maximum amount of domestic garbage generated during the construction period is 40 kg/d. The total amount of domestic garbage generated during the construction process is 7.20 t, which is transported by the construction party to the construction waste designated by the local department. Buried field treatment has less adverse effects. 6. 3 Main major pollution sources and control measures during the operation period 6. 3.1 Main main pollution sources and control measures during the construction period of the school construction project (1) Exhaust gas The air pollutants during the operation period after the completion of the school mainly include the following aspects: 1 canteen fume: The canteen of this project uses clean energy such as natural gas and electricity, and a small amount of soot will be produced during cooking and frying. There are 1446 teachers and students in this project. According to the relevant data of the survey, the consumption of animal and vegetable oil per person per meal is 0.02kg, and the fuel consumption is 28.92 kg/d. When the cooking loss is about 3%, the cannon smoke is 0.87 kg / d, 0.23 t / a, soot initial concentration of about 10 mg / m 3. By setting up a lampblack purifier, the soot concentration after purifying and degreasing is less than 1.5 mg/m 3. 2 Grid odor: Since the sewage water quality of this project is simple and the water volume is not large, the grid odor generated is small. 3 Garage exhaust: There is a parking garage on the ground floor of the canteen building of the project. There are about 88 parking spaces, so the vehicle will generate certain exhaust gas in the process of entering and leaving the garage. Due to the short time the vehicle is running, a small quantity of exhaust gas generated, the main pollutants of NO xand HC. 4 Diesel generator exhaust gas: The standby diesel generator mainly supplies power to classrooms, office buildings, canteens, etc. in case of power failure, so the amount of exhaust gas generated is small. (2) Waste water According to the characteristics of the project, the wastewater during the operation period of the project mainly comes from the occupational middle school office building and the teaching building domestic sewage, the canteen dining wastewater and the laboratory wastewater. The road works and the rainwater and sewage diversion pipe network project do not produce sewage wastewater during the operation period. School 85% according to the amount of generated waste water is calculated, the average daily wastewateremissions project about 360.16 m 3 / d, the total annual emissions of about 112527.50 m 3 / a. School set a grill well for wastewater treatment, wastewater does not contain toxic heavy metals and other harmful substances, and produce a small amount of water is discharged directly into the grid well treatment, the main grill well to intercept debris, garbage and other solid waste. The canteen wastewater enters the grid

82

well after oil separation and sedimentation, and the catering wastewater is 51.48m 3 /d ; School analogy the same type sewage outfall monitoring results, the concentration of pollutants in sewage values: SS300mg / L, COD500mg / L, animal and vegetable oils 60mg / L, NH 3 - N40m g / L. The concentration range of food waste water pollutants is: SS500mg/L, COD1000mg/L, animal and vegetable oil 150mg/L, NH 3 - N50mg/L. According to the above results, the occurrence of pollutants in the wastewater of the proposed project is shown in Table 6. 3 - 1.

FIG. 6.2 -1 proposed project FIG water balance Unit: m 3 /d Linshui second sewage treatment plant construction in 2016, the use of improved oxidation ditch biological treatment process, the size of which is designed as a 30,000 m 3 / d, Early daily processing reached 15,000 m 3 / d, supporting pipeline network length of about 10 km, project investment of nearly 80 million yuan. The main sources of sewage are urban domestic sewage and industrial enterprise wastewater. The sewage treatment plant adopts the rain-soil diversion system, and the effluent implements the first-class A standard of the“Emission Standard for Pollutants in Urban Sewage Treatment Plants” (GB18918-2002). July 2018 Linshui second sewage treatment plant has been put into trial operation. Therefore, after the completion of the project, the teachers and students' domestic sewage can enter the sewage treatment plant to meet the discharge standards. (3) noise 1 noise source is strong According to the characteristics of the project, the noise during the operation period of the project mainly comes from road vehicle traffic noise and school crowd noise, air conditioning compressors (computer room, lecture hall, conference room, etc., separately set up cabinets or wall-mounted air conditioners), pump noise canteen exhaust ducts Smoke fan noise, the project school has no central air conditioning cooling tower.

And the bottom of the split air conditioner main unit is installed according to the cushion or installed in the dedicated equipment room. 3) Select low-noise models when using kitchen equipment in the canteen, and take measures such as sound insulation, noise reduction, sound absorption and vibration reduction during installation : the fume purification device and the induced draft fan are set indoors, and the bottom is provided with a vibration damping pad. The muffler and the induced draft fan shall be provided with an acoustic enclosure. And strengthen daily equipment maintenance to ensure the normal operation of the equipment. 4) After the proposed project is put into use, the later management department should strengthen the daily maintenance and maintenance of the equipment to ensure the normal operation of each equipment to avoid noise pollution caused by equipment failure. 5) It is recommended to arrange three-dimensional greening around the school to form a school green belt that integrates sound insulation and landscape to reduce the impact of school noise on the surrounding area. (4) Solid waste The solid waste during the operation period is mainly domestic garbage generated from school

85

activities, canteen kitchen waste, laboratory-generated hazardous waste, medical waste, and grid well sludge. Referring to the type of the current situation school, a laboratory waste oil generated about 0.05t / a, waste containers about 0. 40 t / a, waste batteries 0.0 5t / a and the like. Specific production sewage 6.2 Table 6.

The garbage dump started construction in 2006. After the completion of the project in 2008, it began to dispose of domestic garbage, which was built and operated by Linshui County Xingxing Environmental Protection Co., Ltd. The service scope of the municipal garbage disposal site in Linshui County includes the neighboring water county town and 45 townships within 50km of the county town. According to operational data, as of December 2017, Linshui city landfill garbage actual processing capacity has reached 150 ~ 180t / d, treatment of domestic waste have been accumulated amount of 500 000 m 3, there are 594 100 m 3 capacity. Therefore, it is feasible to transport the domestic garbage of this project to the landfill. 6. 3.2 Main main pollution sources and control measures during road operation and rain and sewage diversion project operation period After the completion of the project, the existence of roadbed pavements and bridges and vehicle traffic have different degrees of impact on the social and economic environment, ambient air, acoustic environment, water environment, landscape ecological environment and soil erosion along the line. (1) Socioeconomic environment After the completion of road maintenance and rain and sewage diversion projects, the

86

environment along the route has been beautified, the living environment of residents has been effectively improved, and road traffic, industrial park areas and environmental protection construction have been promoted. Therefore, the completion and operation of this project will promote the social and economic development, park planning, infrastructure construction and transportation of the areas along the line. (2) Ambient air After the completion of the road maintenance project of the project, the generation of dust in the vehicle exhaust and the driving of the vehicle during the operation period is the main source of air pollution during the road operation period. The main components of car exhaust gas of NO x and CO and other hydrocarbons. Due to the current promotion of the use of unleaded gasoline in the country, the content of lead in the exhaust gas is small and has little impact on the environment. Road project is located in the industrial park, the current traffic flow is close to saturation, according to the monitoring results of this evaluation, the project area ambient air to meet the "Ambient Air Quality Standards" (GB3095- 2012) secondary standard, good quality of the environment where the project area, car exhaust The impact on ambient air quality is not obvious. Road has been built according to the operation of the car exhaust gas monitoring data statistical survey results, operating range of the exhaust on the car is mainly concentrated in the road on both sides of the road centerline distance 60m range, after the completion of the project road maintenance works on both sides of the road inadditional greening project To a large extent, it can reduce the pollution impact of road vehicle exhaust on both sides of the road. Therefore, this evaluation no longer accounts for vehicle exhaust pollutants. (3) Acoustic environment The high-speed driving sound of the car after the completion of the road maintenance project of this project is caused by the noise generated by the high-speed running sound, the tire and the ground rubbing sound, and the working sound of the engine. Road project is located in the industrial park, the current traffic flow is close to saturation, according to the monitoring results of this evaluation, the project area day and night noise levels are met 4 a class standards "Environmental Quality Standard" (GB3096-2008). After the road maintenance project of the project is completed, the road will be changed from the original cement road to the asphalt road, and the addition of greening works on both sides of the road can greatly reduce the noise source during the driving process. Therefore, this evaluation no longer accounts for the strong source of automobile noise. (4) Water environment The main impact on the water environment after the completion of the road maintenance project of this project is that the rain washes the road surface during heavy rain, and some sediment and oil on the road surface are flushed into the water body. According to the research results, road surface pollutants have little effect. In addition, after the completion of the rain and sewage

87

diversion comprehensive remediation project of this project, the scattered sewage discharge points along the line will be treated, and the sewage discharge amount of the road section will be reduced. In general, the project will not have a negative impact on the local surface water quality. (5) Landscape ecological environment As an indispensable part of the project, the road greening project of this project not only plays a role in beautifying the landscape, improving the safety of driving, but also has a positive and effective effect on timely restoration of the original vegetation in the area, preventing soil erosion, and reducing the dust of the car. Absorbing car noise has good effects. The implementation of this road has paid great attention to the greening projects within the roads and reserved greening land as much as possible. A 2m wide green belt is set on the sidewalks on both sides of the road embankment to form a strip greening, and a tree is planted every 5m to form a point greening. The sidewalk greening uses green trees of excellent street trees, road embankments and roadside permanent slopes to plant lawn shrubs, combined with slope protection to carry out slope greening, and try to reflect local characteristics. (6) risk The main reason is that vehicles carrying toxic or dangerous goods will cause certain harm to human health and water environment after a traffic accident occurs on sensitive roads along the route.

After the completion of the pipe construction, the ground will be restored to greening. There is no permanent land occupation and the land occupation is temporary land occupation. The temporary land occupation area is mainly laid along the existing roads, and the temporary land occupation type is road and municipal facilities land. The temporary land occupation of the project is mainly the land occupation of temporary access roads, the layout of construction sites, and the setting of land backfilling areas. The construction site of the project school is the primary and secondary school land planned by Linshui County. The site is now a wasteland. The ground is shrub vegetation. There is no forest land. The soil erosion is not obvious. There is no precious vegetation and flora distribution in the site. There are no major environmental sensitive points and nature. protected area. The ecological impact of the construction site of the school construction project is mainly to destroy the surface vegetation and the physical structure of the soil, and at the same time to aggravate the soil erosion to some extent. The EIA requires that the construction management should be strengthened during the construction of the project, and the site should be set up strictly according to the design. It is strictly forbidden to open the access road and occupy the surrounding land. After the completion of the construction, the construction unit shall level the temporary road surface and the site, carry out greening and re-cultivation, and restore vegetation. After adopting the above-mentioned restoration measures, the impact of construction land occupation is temporary and disappears with the disappearance of construction. 7.2 Impact of construction on terrestrial ecology During the construction process, the excavation of earthwork and temporary land occupation will affect the surface vegetation. The main line along the project is shrubs, green lawns and some trees. It does not involve tall vegetation and famous wood.

91

Tree, does not involve transplanting. Most of the project construction is mainly along the completed road construction. The construction area is affected by humans. The main animals are rodents such as rats. No rare animals are found in the construction area. The land occupation during construction will have certain impact on the activities of the animals, but after the completion of the construction, the animals will gradually recover with the restoration of vegetation, with little impact. 7.3 Ecological environmental protection measures during construction period 1 For the construction of temporary land occupation area, drainage and water guiding work should be done to prevent environmental pollution and soil erosion caused by siltation; earth and stone excavation should be piled up along the excavation pipe ditch, and closed enclosures should be set on both sides, covered with plastic cloth. Backfilling 2 After the temporary land occupation of the construction is completed, it should be leveled in time to restore vegetation greening; 3 Speed up the construction schedule, shorten the construction period and reduce the impact of construction impact.

limited to the construction site and along the transportation line and are non-continuous pollutants. In addition, the dust-producing operations during the construction period include land excavation, backfilling, transportation, and open-air stacking of residual soil. In the case of drought and no rain, plus strong winds, the dust on the construction site will be more serious. Under normal circumstances, the construction site and construction roads are affected by the dust generated by natural wind within a range of less than 100m. The above-mentioned exhaust gas pollutes the surrounding atmospheric environment to make the dust more serious. In order to reduce the pollution level and scope of dust, the construction unit can take the following measures: (1) It is necessary to clean the sand, cement and other boring at the construction site in time. The gravel yard and construction road should be sprinkled regularly to suppress dust. Sprinkle water 4-5 times a day, can effectively control the construction dust, can reduce the TSP pollution distance to 50m. (2) Powdered materials such as cement and lime should be filled or bagged. It is forbidden to transport in bulk. It is strictly forbidden to scatter dust during transportation. When storing, it should be piled up in the warehouse or covered with tarpaulin; (3) The pollution caused by transport vehicles and some construction machinery during idle, deceleration and acceleration is the most serious. Therefore, on the one hand, the construction vehicle and some construction machinery should control the speed of the vehicle to make it less than 40Km/h to reduce road dust during driving; on the other hand, shorten the idle speed, deceleration and acceleration time and increase the normal running time. (4) wind speed for more than four easy to produce dust, the proposed excavation contractor should pause, take cover stacker, moist soil surface. (5) Clean up the construction site in time after the completion of the project. For construction sites, construction camps, and stockyards, in addition to timely cleaning, greening or restoration of vegetation should be carried out. In summary, during the construction period, the local atmospheric environment quality may be affected to varying degrees. Since the construction period is relatively short compared to the operation period, the impact is temporary and can be reversed under normal circumstances. However, if the management is not strengthened, it will cause certain pollution accidents. Therefore, effective prevention measures should be taken, civilized construction should be emphasized, environmental management requirements should be strengthened, work responsibility system should be formulated, and the supervision and management of environmental protection departments should be obeyed. This evaluation believes that the atmospheric environment quality of the project area will not have obvious adverse effects due to the construction of the project after taking corresponding measures, and this impact will disappear with the completion of construction.

8. 2. 1.2 Environmental impact analysis of surface water during construction period The wastewater generated during the construction of the school construction project mainly includes the domestic sewage of the construction workers and the wastewater generated by the construction itself, mainly including COD, SS, animal and vegetable oil, BOD 5, petroleum and other pollutants. If the wastewater is directly discharged, it will produce stinky Gas, breeding mosquitoes, etc., have an adverse impact on the environment. The EIA requires the temporary storage pool in the construction camp to collect the domestic sewage from the construction camp and use the municipal suction truck to transport it to the sewage treatment plant for disposal. This will ensure that the domestic sewage will be effectively treated during the construction period, and the domestic sewage will not be discharged. The water body, so a small amount of domestic sewage generated during the construction period has little effect on surface water. The construction site includes construction and maintenance, which will produce wastewater. The pollutants in the wastewater are mainly SS and contain a small amount of oil. It is recommended to set up a sedimentation tank, and the wastewater will be recycled after being separated by oil separation and sedimentation. Without access to surface water, the environment is acceptable. 8. 2. 1.3 Acoustic environmental impact analysis during construction period The noise of this project mainly comes from the noise of transportation vehicles and construction facilities. During the construction process, the noise of non-mechanical operation is generally 65 decibels, and the noise of transportation vehicles and construction facilities is generally around 85 decibels. The construction noise within 10 m radius ofthe construction site, the vast majority are exceeded, a small part of the excessive phenomena also occur 15 0 m. During the construction period, the number of vehicles passing by the road will increase, which will cause the traffic noise value to rise. Therefore, it is necessary to minimize the noise impact during the construction period, especially at night construction, and measures must be taken to strictly control it. (1) Noise impact prediction The prediction of noise sources during construction is usually considered a point source prediction calculation. According to the point source attenuation mode, the noise value of the different distance sensitive areas from the source can be estimated. The prediction mode is as follows:

L Aeq  L po  20 lg( r / r0 )

Where: L Aeq is the construction noise from the sound source r m [dB(A)], L po is the sound level [dB(A)] at the sound source r 0 m, A attenuation constant, dB(A). r is an (m) the distance from the sound source, r 0 to (m) from the prediction result from the sound source at different distances from the construction machine in Table 8.2 --1.

95

Table 8.2 -1 construction equipment and a variety of strong noise source at different distances (dB) Mechanical Sound source Noise prediction value model characteristics 5m 10m 20m 40m 50m 100m 150m hydraulic Unstable 90 84 78 72 70 64 60 excavator source Flow Loader instability 87 81 75 69 67 61 57 source Unstable Rock drill 85 79 73 67 65 59 55 source Fixed stable Air compressor 98 92 86 80 78 72 68 source Fixed stable Tower crane 84 78 72 66 64 58 54 source Unstable Vibrating rod 98 92 86 80 78 72 68 source Flow Truck instability 97 91 85 79 77 71 67 source Construction noise characteristics and hazards: Although the equipment noise is generated during the construction period, it is very harmful to the environment, especially the construction workers, due to its impact, long duration and strong vibration. The equipment invested in different construction stages has different effects on environmental noise.It is mainly the trench excavation and filling of pipelines, leveling the land, mainly based on the noise of various transportation vehicles. The operation of construction equipment is dispersive, the noise is fluidity and instability, and the impact on the surrounding environment is not obvious. Construction noise is largely determined by the distance between the construction site and the above sensitive points and the construction period. The closer the distance is, the greater the impact on construction at night. The noise impact during the construction period is short- lived. Once the construction activity is over, the construction noise will also end. As can be seen from the table, daytime construction noise evaluation criteria drop to about 70dB from the noise source 150 m, the range of m visible inside the noise impact on the environment in the periphery of the construction site from 20 to 150. After field surveys, there are no sensitive points such as residents, schools and government units within 150 m of the project site. Therefore, the impact of noise on the outside world during construction period is small. However, the project should still be civilized during construction, and try to control the generation and spread of noise. Construction operators and on-site construction personnel shall

96

control working hours according to labor hygiene standards and do their own protection work, such as wearing earplugs and helmets. (2) Noise pollution control measures In order to reduce the impact of noise pollution on the construction site of the school construction project, the following technical measures can be taken during the construction process: 1 Replace the pneumatic impact tool with a hydraulic tool; 2 Set a shield around the high noise equipment; 3 In the excavation work, try to avoid using explosive means; 4 If possible, install a muffler to reduce the intake and exhaust noise of various engines; ⑤ rational distribution of the construction site: construction site noise source is fixed relative concentration, placed away from environmentally sensitive location of the receiving body and take full advantage of the terrain, especially running routes carrying heavy vehicles, should try to avoid noise-sensitive areas, Minimize traffic congestion and waiting for driving; 6 Take protective measures for construction workers, such as protective earplugs, frequent rotation operations, etc.: no noise (such as blasting) is prohibited at noon (12 : 00 -14 : 00) and night (23 : 00 - 07 : 00). Construction work that produces high noise pollution. If necessary, the construction unit shall submit a declaration to the environmental protection department with the approval authority within 15 days before the commencement of the project, and explain the prevention measures to be taken. 8. 2. 1.4 Environmental impact analysis of solid waste during construction period Solid waste mainly comes from construction waste, spoil, and domestic garbage generated by construction workers. The accumulation of a large amount of spoil and construction waste not only affects the urban landscape, but also easily causes environmental problems such as soil erosion, ecology and dust. The project produces topsoil that is transported back to other green belts around the project, and the earthwork is transported back to other low-lying areas around the project. The stone-selling stone factory is smashed and sold. Construction waste must be uniformly collected, shipped, and transported to the construction waste dump designated by the urban construction management department for unified disposal. Therefore, the temporary waste generated during construction has a slight impact on the surrounding environment. The garbage collected in the construction camp is collected and sent directly to the landfill for regular disposal by the sanitation department; therefore, the domestic garbage generated during the construction period has little impact on the environment. 8. 2. 1.5 Ecological environment impact and protection measures during construction period At present, the ecological construction of the construction area of the school construction project is simple, no important aquatic and terrestrial plants survive, and the construction area of the project is narrow, which will not have a significant impact on the ecosystem of the whole area. The ecological problem during the construction period is mainly the problem of soil erosion.

97

(1) Soil and water loss factors 1 Due to excavation of the land during construction, the vegetation is stripped and destroyed, and the corrosion resistance of the topsoil is weakened, which easily causes soil erosion. 2 The earth and rock slag in the construction area is prone to soil erosion. 3 The earthwork in the construction is restricted by the topography and transportation conditions. When it is inconvenient to transport away, due to its loose structure and large porosity, it is easy to produce soil erosion. Especially in the rainy season from June to September, it is easier to form the peak of soil erosion. However, after the project is completed, the regional ecological environment will be restored with the implementation of greening. (2) Mitigation and protection measures: 1 During the construction period, the project will be rationally designed to achieve district and stage excavation, so that soil erosion will be reduced to a minimum. It is forbidden to excavate at the same time in the whole line or in multiple sections under the condition of slow construction progress, forming a large area of soil erosion. 2 Construct the interception ditch and drainage ditch system in the site, and introduce a large amount of rainwater into the flood ditches to reduce the erosion of the surface soil and new vegetation. 3 According to the topography of the construction area, reasonably plan the location of the backfill and pre-build the retaining wall to avoid the erosion of loose topsoil in the construction area by surface runoff. 4 Reasonably arrange the construction progress, try to avoid the construction of the rainy season as planned, especially the foundation excavation should avoid the construction of rainstorm days to minimize the soil erosion. The loose topsoil can be covered with plastic cloth to reduce the impact of soil erosion. 5 The construction fill should be repeatedly crushed by the road roller according to the requirements of the construction code, and the dense pressure humidity is 85 ~ 90% to reduce the impact of soil erosion caused by rain erosion. 6 After the completion of the construction, the slope is stable, the topsoil of the rock is not exposed, the vegetation is restored, and the greening rate is over 30%. 7 Strengthen management, especially the abandonment of the abandonment of the stone must be supervised by a special person, the construction of the abandoned stone and the disposal of the spoil must be handled by a special person. It can be seen that the impact of the construction period of the project is temporary. After the completion of the construction, the environmental elements of the affected area can be basically restored. As long as the environmental protection measures that should be taken during the construction period are carefully formulated and implemented during the construction period, the environmental impact of the construction can be eliminated or effectively controlled, and the

98

environmental impact can be minimized. ANALYSIS 8. Developed affect 2.2 to roads and rain sewer network environment comprehensive treatment project construction period 8. 2.2 Construction of.1 Atmospheric Environmental Impact Analysis (1) Analysis of pollution sources 1 During the construction period, the construction activities of the earthwork and concrete works, the transportation of materials and the driving of construction vehicles generate dust and dust pollutants. 2 The construction of the project is mainly based on fuel machinery and equipment, and fuel waste gas is generated during construction operations (a large number of vehicles, scrapers, bulldozers, diesel engines and other mechanical equipment emit exhaust gas during operation), mainly including NO x and CO. 3 Asphalt fumes and benzo [a] pyrene generated during asphalt mixing and laying. (2) Environmental impact analysis 1 Dust and secondary dust are generated during the excavation, filling, building materials transportation, drilling, blasting, etc., and the TSP concentration is between 1.5 and3.0 mg/m 3. Under normal conditions, the range is 50 to 100 m. The contribution value can meet the secondary standard of ambient air quality; in the case of high wind (>5 grade), the requirements of the secondary standard can be met from 100 to 300 m. Due to the high static wind frequency in the project construction area, the TSP impact under normal circumstances. It is limited to the construction work area within 100m and has little impact on the ambient air quality. If the designated personnel regularly sprinkle water for 4to 5 times at each dust-producing site in the construction site during the construction period, the TSP pollution distance caused by dust can be reduced to 50m. In addition, temporary baffles are set around the construction area for temporary construction on the construction site. The soil and material yards are covered by film, and the roads for entering and leaving the transportation vehicles and entering and leaving the site are strengthened. The closed transportation can greatly reduce the impact of dust and dust on the surrounding environment. In addition, the living fuel in the construction camp uses clean energy, and the exhaust gas has little impact on the environment. 2 During the construction period, the main pollutants are SO 2, NO X and CO. Due to the intermittent nature of the discharge, the construction waste gas is mainly limited to the construction work site and the transportation road. Through reasonable construction organization, reduce the idle time of construction machinery and equipment, strengthen the maintenance of mechanical equipment, reduce the emission and emission concentration of construction machinery and equipment, and reduce the impact on the surrounding environment. 3 The asphalt fume and benzo [a] enthalpy analogy generated during the asphalt paving process during the construction period may exceed the standard within the dominant wind direction of 100m, and meet the environmental standard requirements beyond 100m. In order to reduce the

99

pollution of asphalt smoke to the surrounding atmospheric environment and protect the health of residents along the line, this project does not set up an asphalt mixing station, directly uses prefabricated asphalt, and only paves the pavement on site. 4 In the asphalt mixing process, the main toxic and harmful substances in the flue gas are THC, phenol and benzo [a] pyrene. The closed agitating process with dust removal equipment is used to transport the asphalt to the paving site without heat source or high temperature container. Therefore, the emission concentration of asphalt flue gas is low, which can meet the maximum allowable emission concentration of asphalt flue gas in the Comprehensive Emission Standard for Air Pollutants (GBl6297-1996), and has little impact on the surrounding environment. (3) Control measures In view of the characteristics of the secondary dust on the construction site, in order to control its pollution, the evaluation requires the construction unit to strictly control the construction dust pollution during the construction process. The main measures include: 1 Before the pavement is broken, it is necessary to remove the dust on the road surface. In the process of dismantling, the sprinkler is installed to spray the dust on the working area. 2 Once the transport vehicle sprinkles spoil and slag, it must immediately organize cleaning to keep the road clean; it is strictly forbidden to transport spoil and waste slag in rainy days to prevent spoil and slag from being directly brought into the surface river by rain. 3 Building materials and Jianye transportation vehicles are sealed to prevent materials from being scattered along the way. 4 Transportation passages and material yards, slag yards, earthwork temporary storage yards, etc. are far away from the forest around the construction site, and it is absolutely forbidden to cross through them; the street trees that transport the passing roads are regularly sprinkled with water. 5 It is not advisable to use construction machinery with high fuel consumption, low efficiency and serious exhaust gas emissions in the project area. It is necessary to rationally allocate fuel oil equipment, strengthen management, and require exhaust gas emission standards for newly purchased transportation vehicles. 8.2.2.2 Analysis of the impact of surface water pollution (1) Construction wastewater The construction wastewater during the construction period of the proposed project is mainly composed of concrete curing wastewater, construction machine flushing water and pipeline test water drainage. The main pollutants are SS and petroleum. During the construction process, the “one water, multiple use, reuse and water conservation” are strictly implemented. In principle, after the sedimentation and grease trap treatment are set in the construction site, all of them are reused as dust-proof and water-spraying in the site, and no drainage is required. (2) Domestic sewage of construction workers During the construction period of the project, the domestic sewage generated by the construction personnel is about 0.68 m 3 /d. Due to the road reconstruction, the regional sewage pipe network

100

is also reconstructed at the same time, but the municipal pipe network in the surrounding area is perfect. Therefore, the domestic sewage is collected and treated by the surrounding municipal service facilities. Entering the second sewage treatment plant in Linshui County to further discharge the standard discharge, and have less impact on the water environment of the surrounding area. 8.2.2.3 Noise pollution impact analysis and prevention measures (1) Analysis of noise pollution impact 1 pollution source analysis During the construction period, various machines, such as road pavers, loaders, drilling rigs, excavators and other high-noise equipment will be used. These equipments will affect the acoustic environment near the construction area during construction. Common road construction machinery noise source intensity supra Table 6.2 - 2. 2 Environmental impact analysis There are many construction equipments and high noise levels, and it is difficult to take measures such as sound absorption and sound insulation on the construction site to control its environmental impact. The effect of noise can only be mitigated by controlling the distance. In order to reflect the scope of the construction of noise to the environment, using the distance propagation attenuation model to predict the range of construction machinery noise pollution. The attenuation mode is: L P2 =L P1 -20Log (r 2 /r 1) Where: L P2 : the sound level at the sound point P 2 ; L P1 : the sound level at the sound point P 1 ; r 2 : the distance from the sound source to P 2 ; r 1 : The distance from the sound source to P 1. Using Table 6.2 - 2 stream of sound intensity calculation range noise pollution construction machinery, i.e., the construction work noise value from the point of compliance. The specific calculation results are shown in the following table: Table 8.2 - 2 Construction machinery noise impact range prediction Unit: dB (A) Distance (m) 5 10 20 40 60 80 100 200 device Loader 76.0 70.0 64.0 58.0 54.4 51.9 50.0 44.0 Roller 67.0 61.0 55.0 49.0 45.4 42.9 41.0 35.0 bulldozer 72.0 66.0 60.0 54.0 50.4 47.9 46.0 40.0 excavator 70.0 64.0 58.0 52.0 48.4 45.9 44.0 38.0 Mixer 72.0 66.0 60.0 54.0 50.4 47.9 46.0 40.0 Truck 71.0 65.0 59.0 53.0 49.4 46.9 45.0 39.0 Press the "Environmental Quality Standard" (GB3096- 2008) Class 2 District standards, standard daytime distance of about 40m, the standard distance at night is about 100m.Obviously,

101

the noise of construction activities will be the largest Buddhist temple and residents along the East Branch Road on the north side of the world in a residential area families have some impact, especially at night influence more apparent. However, the noise impact during the construction period is short-term and temporary. Once the construction activity is over, the construction noise impact will disappear. (2) Control measures Construction machinery noise generated will adversely affect the sensitive points along the project, to mitigate the adverse effects, the need to take the following measures: 1 All kinds of mechanical construction should pay attention to the control distance. According to the prediction of the noise of engineering equipment, it is better to keep the spacing of the main noise sources more than 5m, in order to minimize the noise source and superimposed on the environment under the condition of high sound level. influences.Attention should be paid to the reasonable arrangement of construction time and the placement of mechanical equipment to minimize noise disturbance. 2 Under the premise of meeting the construction needs, select low-noise low-noise equipment as much as possible, control the use of high-noise construction equipment, and adjust the time of high-noise construction, and arrange the noise-hungry operations as much as possible during the day. 3 Strengthen the management of power machinery equipment in the construction area, and arrange according to the surrounding environment reasonably, so that the strong sound source is as far as possible away from the sensitive area, and the high noise source power equipment can be placed in the temporary room. Strengthen the maintenance of construction machinery to avoid the occurrence of mechanical noise increase due to poor equipment performance. 8.2.2.4 Solid waste control measures (1) Source of solid waste generation Solid waste during construction, including earthwork, concrete waste, abandoned slag, construction waste and other garbage dredging silt life and Construction construction workers produced.. (2) Solid waste pollution prevention measures If the solid waste of the proposed project is not properly treated, it will not only cause soil erosion but also inconvenience to pedestrians under the action of rainfall.Therefore, effective prevention measures should be taken during the construction of the project, including: 1 The road maintenance project breaks the waste concrete block produced on the road surface and sells it to the waste stone processing factory. After the crushing process, it is sold as stone material; 2 Rainwater pipe network construction The sludge produced by the original pipe dredging process is dried and disposed of with the garbage by the sanitation; 3 The domestic garbage in the construction shall be treated by the urban sanitation

102

department after being bagged ; 4 Reasonably arrange the construction progress, and the foundation excavation should avoid the rainstorm season and prevent soil erosion; 5 Early construction of slope protection, retaining wall and other prevention of soil erosion. 8.2.2.5 Analysis of construction impact on traffic (1) Analysis of the impact of urban road traffic According to the project design plan, no specific plan was proposed for the construction organization. The EIA and the design unit and the owner unit negotiated to initially determine the existing roads for the project to be converted into sections and half-width construction methods. At the first 500m, a warning sign is set to remind the passing vehicles to pass through and control the speed of the vehicle, and equipped with special management personnel to be responsible for on-site command and guidance, to minimize road congestion caused by project construction and to ensure smooth road traffic in the area; Whenever possible, avoid the peak traffic season, the pavement construction should be shortened as much as possible, and the asphalt pavement should be properly arranged at night. It also can post announcements through on-site, or radio, television and other news media to inform the masses this section of the demi information before construction started, so that drivers who choose to live honestly, to reduce the volume of traffic from the source, thereby reducing road congestion The chance. After comprehensively taking the above measures, the impact of road reconstruction on existing road traffic can be reduced. In addition, during the construction period of the proposed project, all construction materials and earth and stone are transported by trucks. The transport roads are mainly transported by Yuma Road. The transport vehicles avoid the peak hours of commuting, weekends and holidays. Due to the short construction time of the project, the engineering volume is not large, and the number of transportation vehicles is small. By reasonably controlling the transportation time, the impact on regional traffic is small. (2) Construction organization recommendations 1 During the construction of road works, avoid the road traffic peak period during material transportation, concrete transportation and cast-in-place, and occupy less land as much as possible. Minimize the construction period for road pavement construction. It is recommended that the construction unit and the construction unit formulate a traffic organization plan, and cooperate with the traffic police department and the relevant departments of the industrial park to do a good job in traffic organization to avoid the inconvenience caused by the implementation of the project. Since most of the materials in this project are transshipment in Linshui County, it is necessary to coordinate the park plots to avoid traffic congestion. Vehicles should slow down when passing through residential areas to avoid affecting residents' lives. After taking the above measures, the impact of the construction period on the surrounding traffic environment can be reduced. 2 During the construction of the project, strengthen communication with the management

103

department of the industrial park to ensure that the construction of the road will minimize the impact on the construction of the light rail track and the construction of the platform. 8.2 Environmental Impact Analysis during Operation Period 8.2.1 Environmental Impact Analysis of School Construction Projects 8.2.1.1 Atmospheric environmental impact analysis After the project of school construction projects put into operation, mainly for atmospheric pollutants canteen, gas and other odors generated when the grill well, garage exhaust and diesel generator emergency power generation. 1 canteen fume: The proposed project will produce a small amount of food fume, and its soot concentration is 10 ~ 15mg / m 3. After using the lampblack purifier (treatment efficiency 90%), it is discharged through the special flue to the roof and has a small impact on the surrounding environment. 2 Grille odor: The grid odor is collected by pipelines and then discharged to the green belt through special pipelines, which has little impact on the surrounding environment. 3 Garage exhaust: The garage exhaust emission is small, and the mechanical exhaust system is led to the center of the ground green space by a dedicated pipeline. The discharge port is in the form of blinds, which has little impact on the environment. 4 Diesel generator exhaust gas: adopts a new generation of environmentally-friendly air-cooled self-starting diesel generator set, which generates less exhaust gas, and the exhaust gas and garage exhaust gas are led to the central green space of the ground through a dedicated flue, because the equipment is emergency use, frequency Less, less impact. After the above measures are taken, the emissions generated by the project have less impact on the environment. 8.2. 1.2 Wastewater Impact Analysis and Measures After the completion of the project, the main sewage is canteen dining wastewater, teachers and students domestic sewage, laboratory wastewater. The school builds a grid well to collect and treat wastewater, and the oily wastewater generated in the canteen is discharged into the grid well and treated with domestic sewageafter oil separation treatment. The wastewater of the proposed project will be treated by the grid well to reach the Class III standard of Integrated Wastewater Discharge Standard (G B8978-1996), and then enter the municipal sewage pipe network and be treated in depth by the second sewage treatment plant of Linshui County to reach the pollutants of the urban sewage treatment plant. emission standards "(GB18918-2002) after an A standard into the small West River and eventually into the river banana. The sewage generated by the project will not have a significant impact on the water quality of the Xiaoxi River and Bajiao River. Linshui second sewage treatment plant construction in 2016, the use of improved oxidation ditch biological treatment process, the size of which is designed as a 30,000 m 3 / d,Early daily processing reached 15,000 m 3 / d, supporting pipeline network length of about 10 km, project

104

investment of nearly 80 million yuan. The main sources of sewage are urban domestic sewage and industrial enterprise wastewater. The sewage treatment plant adopts the rain-soil diversion system, and the effluent implements the first-class A standard of the “Emission Standard for Pollutants in Urban Sewage Treatment Plants” (GB18918-2002). July 2018 Linshui second sewage treatment plant has been put into trial operation. 8.2. 1. 3 Noise Environmental Impact Analysis After the project is completed and put into schools, mainly to noise equipment noise crowd noise, outdoor air conditioners, kitchen fans, pumps, diesel generators. The sports field is located on the east side of the block, away from the office and teaching buildings. The tall trees are planted around the stadium. The noise of the crowd has little impact on the surrounding acoustic environment. The outdoor air conditioner and the kitchen fan are less noisy. During the design of the building, the air conditioner outdoor unit is Set in the outer part of each floor plane, in the direction of the open space, the air conditioner outdoor unit cannot be oriented toward the office building or classroom window to prevent the impact on students' life and daily education. Wherein the pump is noisy diesel generators and noise, the noise source strength of about 80 ~ 90dB, diesel generators disposed on the negative 1 layer underground construction, consider the use of sound insulation in buildings and other measures can effectively reduce the vibration noise of the environment The impact of equipment noise on the surrounding acoustic environment is small. 8.2. 1.4 Impact analysis and measures of solid waste The solid waste generated during the operation period of the project is mainly domestic garbage for teachers and students, kitchen waste for canteens, hazardous wastes generated by laboratories, medical waste, and sludge from grids. Domestic garbage is generally solid waste, which is bagged. It is collected by special personnel and stored at the garbage collection point every day. It is collected andhandled by the municipal sanitation department. The domestic garbage has little impact on the environment. In order to prevent the long-term accumulation of domestic garbage to produce odor and breeding mosquitoes and flies, management should be strengthened to ensure daily Nissan. Canteen food waste and other garbage classification, set up a dedicated food waste collection bucket next to garbage collection point, while doing seepage, rain, sun protection, cross sanitation department of the collection, transportation, treatment.The hazardous wastes generated by the laboratory are classified with other domestic wastes. Special collection bins are set up in the laboratory to collect waste engine oil and containers, and waste batteries respectively. After sorting and collecting, the qualified units are uniformly collected and transported. Clinic medical waste and other garbage classification, set up a group of dedicated medical waste collection bucket in the infirmary, pay qualified units unified collection, transportation, treatment. Grill well sludge to be regularly (generally once per quarter) Qingtao, using sealed garbage trucks to collect removal, garbage sent to landfills for disposal.

8.2. 2 Environmental impact analysis of road and underground rainwater pipe network comprehensive improvement project 8.2. 2.1 Atmospheric environmental impact analysis According to the results of this evaluation, the atmospheric environment of the project area meets the Class II standard of Ambient Air Quality Standard (GB3095-2012), whichindicates that the current automobile exhaust gas has little impact on the air environment along the road during the road operation. The change factor of bicycle emission factor is not considered in the prediction of motor vehicle exhaust pollution. With the continuous improvement of automobile manufacturing technology and the improvement of people's environmental quality requirements, the state will formulate increasingly strict vehicle emission standards and bicycle emission factors. It will be getting lower and lower. The project belongs to the technological transformation projects, the project is completed the same route from the original pavement into asphalt concrete pavement, while the construction unit in the green sides of the road, further slowing car exhaust and dust impact on the surrounding ambient air. After taking the above measures, the exhaust gas generated by road driving has less impact on the environment. 8.2.2.2 Analysis and measures of wastewater impact The road does not have a service area, and there is no wastewater discharge during the project operation period. The research shows that in the case of relatively consistent road surface pollution load, the surface runoff pollution generally increases with the increase of rainfall in the early stage of rainfall. After a period of rainfall, the pollution will gradually decrease, and the main pollutant in the surface runoff is SS. After collecting rainwater rainwater pipes laid along both sides import small river, and finally sinks into Bajiaohe, it will not affect the surface water. 8.2.3 Noise Environmental Impact Analysis (1) Acoustic environmental impact analysis Class 3, 4a standards based on monitoring results of this evaluation show that the project meets the appropriate road traffic noise "Environmental Quality Standard" (GB3096-2008). The area where the road of the project is located belongs to the industrial park, and the roads are all industrial enterprises. The road traffic noise has no obvious impact on the surrounding environment. At the same time, this project belongs to the technical transformation project, the same way the road after the completion of the project from the original concrete pavement into asphalt pavement noise reduction, while the construction unit in the green sides of the road, the vehicle further mitigate the impact of noise on the surrounding sound environment. (2) Road noise reduction measures ① should be rational use of surface features landforms, green belts as noise barriers, its construction should be combined with noise reduction requirements, surrounding land use and planning, landscape planning requirements;

106

2 Strengthen the road layout green belt. The green belt should choose evergreen plants with lush foliage and rapid growth according to local natural conditions. Joe, irrigation and grass should be properly matched with dense planting. The planned green belt should be constructed in parallel with the ground transportation facilities ; 3 The construction party shall set a deceleration and banned sign in the section of the neighboring waters; 4 The construction party shall conduct road inspections in time to reduce the noise radiation generated by abnormal friction. The end of the road north of the project area land use planning is mainly commercial, residential land mainly in view of these plots are more sensitive to noise, to reduce the impact of traffic noise on urban planning should adhere to both sides of the main road within a range of 30 m The first row of buildings should not be built with noise-sensitive buildings such as residential areas, schools, hospitals, etc. If it is necessary to construct, noise reduction measures should be taken in its own design, such as the use of double-layer sound insulation windows. 8.2. 2.4 Solid waste impact analysis and measures The solid waste in the road operation process of the project is mainly caused by the sediment and litter caused by the driving of the automobile. It is uniformly cleaned by the sanitation department, and the solid waste generated has little impact on the environment. 8. 2.2.5 Environmental risks during road operation (1) Environmental risk impact analysis The road of this project is located in the industrial park. There is a possibility that dangerous goods transport vehicles will pass through. If a dangerous goods vehicle has a traffic accident and causes toxic and harmful chemical substances to leak, it will cause a certain range of vicious environmental risk accidents in a short time, which not only brings serious economic losses, and will bring serious pollution to the environment, cause significant harm to nearby residents, mainly in two aspects of it. 1 In the process of transporting highly toxic and highly toxic chemical substances, a large amount of leakage occurs and flows into surface water, and the pollution consequences will be very serious. 2 Transportation of highly toxic, flammable, high-explosive chemical vehicles through traffic accidents along the environmentally sensitive areas along the line, such as residential areas, causing a large number of toxic and hazardous substances to leak, or causing fires and explosions, the environmental risk impact is extremely serious. With the country in recent years, traffic safety management efforts to increase the chance of the two environmental risk of getting smaller and smaller. In addition, roadconstruction not produce this sudden risk of direct cause and road quality and road conditions The better, the less likely it is to have a risk, but it should also be taken seriouslyby relevant authorities and certain precautions should be taken to minimize its incidence.

(2) Preventive measures The evaluation suggested that the construction party should set up warning signs for dangerous goods transportation at the entrances and exits of the project and strengthen the management of the inbound vehicles. The transport vehicle shall have a dangerous goods transport permit. The passengers and passengers shall have a certificate of employment, print the words “Dangerous Goods” or set the signs of the relevant words on the obvious position on the transport vehicle, and drive at a speed limit. Keep abreast of the operation of dangerous goods transport vehicles in this section. Once an accident occurs, report to the relevant departments such as transportation and environmental protection in a timely manner so that dangerous goods can be disposed of in a timely and effective manner, and the loss of personal accidents and environmental accidents can be minimized.

After the measures such as operation, watering and dust suppression, the impact on the environment is small. 2 Waste water: The construction workers' domestic sewage is set up and sent to the sewage treatment plant for treatment and discharged to the standard. The construction wastewater is reused after sedimentation treatment. After the above measures are taken, the wastewater during construction period has little effect on surface water. 3 Noise: The construction machinery is noisy and has different degrees of influence on the surrounding environment. Take reasonable arrangements and working time limit, limit high noise entering equipment, strengthen equipment maintenance, reasonable arrangements for construction machinery position, after taking the environmental impact of noise, vibration, noise reduction measures as possible to get effective control. The noise generation during the construction period is temporary, and the noise impact is eliminated after the construction is completed. By adopting the above noise prevention measures, the noise impact on the surrounding environment during the construction period is not obvious. 4 Solid waste: The topsoil is transported back to the green belts in other construction areas around the project. The earthwork is transported back to other low-lying areas around the project, and the stone-selling stone factory is crushed and sold. The domestic garbage of construction workers

124

shall be collected by the garbage bins in the site and then disposed of by the sanitation department ; the construction wastes and abandoned materials generated during the construction shall be transported to the designated place for landfill disposal. After the above measures to deal with a smaller impact on solid waste project construction period. 5 Ecological impact and soil erosion: The land occupation of the project will cause a fundamental change in the land structure, the physical and chemical properties of the soil will change, the urban ecosystem will be more obvious, and the surrounding natural landscape will be blocked. Taking full advantage of the original terrain, minimizing excavation, restoring vegetation as soon as possible, and restoring vegetation to plants with strong ecological suitability, the impact on the environment is limited. (2) Environmental impacts and prevention measures for road maintenance and rainwater and sewage diversion pipe network comprehensive improvement project 1 Exhaust gas: The construction of the fuel machinery is intermittent operation, and the amount of use is small. After strengthening the maintenance and repair of the equipment, the impact on the ambient air is small; the construction dust will have a certain impact on the surrounding environment, and the construction operation is closed. After the measures such as operation, watering and dust suppression, the impact on the environment is small. 2 Wastewater: The construction personnel do not have a centralized construction camp. Relying on the existing facilities, the construction workers' domestic sewage is discharged according to the existing facilities. The construction wastewater is reused after sedimentation. After the above measures are taken, the wastewater during construction period has little effect on surface water. 3 Noise: The construction machinery is noisy and has different degrees of influence on the surrounding environment. Take reasonable arrangements and working time limit, limit high noise entering equipment, strengthen equipment maintenance, reasonable arrangements for construction machinery position, after taking the environmental impact of noise, vibration, noise reduction measures as possible to get effective control. The noise generation during the construction period is temporary, and the noise impact is eliminated after the construction is completed. By adopting the above noise prevention measures, the noise impact on the surrounding environment during the construction period is not obvious. ④ solid waste: break the road construction and gravel concrete to Spoil mainly used as raw materials sand quarry, after pulverization as a raw material recycling; silt sewer network construction of original tubing generated during dredging, cleaning Plastics and other garbage, after the sludge is dried, it is disposed of by the sanitation with the garbage; the construction personnel do not have a centralized construction camp, and the daily garbage of the construction workers is transported by the construction party to the construction landfill designated by the local department, and the adverse impact is small. 5 The road maintenance and rain and sewage diversion pipe network comprehensive remediation

125

project is a technical upgrading project. No new land occupation is required. After the completion of the project, green belts will be added on both sides of the road. After adopting the above measures, the environmental impact will be improved. 11.1. 5. 2 Environmental impact during operation period (1) Environmental impacts and prevention measures during school operation ① exhaust gas: canteen after fume purification process by a dedicated lead to the canteen roof flue emissions. The grid odor is collected by pipelines and then discharged to thegreen belt through special pipelines, which has little impact on the surrounding environment. Garage exhaust emissions are small, and the mechanical exhaust system is led by a dedicated pipeline to the central green space, which has little impact on the environment. The standby diesel generator adopts a new type of generator, and a small amount of exhaust gas generated by emergency power generation is discharged to the central green space of the ground through a dedicated flue, with less frequency, less exhaust gas emissions, and less impact. ② waste: oily wastewater generated through the project cafeteria grease and then treated sewage discharged into the grill well and be dealt with, the project wastewater aftertreatment grill well into the second Linshui County sewage treatment plant through municipal sewer treatment of "urban sewage treatment plant pollutant discharge standard" (GB18918-2002) after an A standard into the small West River and eventually into the river banana. 3 Noise: According to the Regulations on the Administration of Entertainment Places: “It is forbidden to build new metal processing, stone processing, wood processing and other enterprises that generate environmental noise pollution in concentrated areas of noise-sensitive buildings. It is forbidden to protect residential buildings, museums, libraries and cultural relics. In the building of the unit and within 200 meters of the school, hospital, and office, an entertainment venue that generates noise and vibration is established. During the sale (pre-sale) of the commercial housing construction project, the results of the acoustic environmental impact assessment and the sales of the house must be The sound environment quality condition, sound insulation, possible external noise influence and noise pollution prevention measures shall be publicized in a prominent place in the sales place. " Therefore, after the proposed project is completed, it is forbidden to construct high-noise places such as KTV in the surrounding 200m range. After the proposed project is completed and put into use, the noise mainly comes to crowd noise, outdoor air conditioners, kitchen fans, pumps, diesel generators (emergency use) and other equipment noise. The sports area is located on the west side of the block, away from the office building and the teaching building. The tall trees are planted around the sports area. The motion noise has less impact on the surrounding acoustic environment. The outdoor air conditioner and kitchen fan have less noise. During the design, the air conditioner is outdoor. The machine design is set in the outer part of each floor plane. In the direction of the open space, the air conditioner

126

outdoor unit cannot be oriented toward the office building or classroom window to prevent the impact on the daily education of the students. Wherein the pump is noisy diesel generators and noise, the noise source strength of about 80 ~ 90dB, emergency diesel generators is used, a strong noise source about 90dB, underground building equipment rooms provided negative 1 layer, using Building noise insulation and considering measures such as vibration reduction can effectively reduce the impact of noise on the environment, so the impact of equipment noise on the surrounding acoustic environment is small. ④ solid waste: household waste as solid waste in general, the implementation of bags, garbage per day deposited in the collection points by the hand after collection by the municipal sanitation department collected centrally, not domestic waste environmental impact.
