The designed hot water temperature is 130oC, and vapor pressure is designed to be 10.3mH2O, the top point of supply water pipe is 18m, so the constant pressure of this system is 33 mH2O. The primary network adopts continuous make-up water pressurization method, and the initialization pressure is 0.323 MPa, which is the static line of this system. 2.5.5 Pipe Material and Subsidiary Facilities (1) Pipe Material Selection Choose seamless pipe while hot water pipe diameter DN≤150mm, and use spiral welded steel pipe, while DN＞150mm, the pipe steel is Q235A, which quality and specification is correspond with the relevant previsions of the national standards. (2) Valve Selection Install shut-off valves at all the switch points of the network, include start points of trunks and branches, the reserved extension points, and also install breaking valve on every 1.5Km of the distribution lines. Install air bleeders on each top point of the network, and water discharge equipment on each bottom point. Adopt sluice valves while valve caliber DN≤50mm, and butterfly valve while DN＞50mm, select 2.5 MPa as the nominal pressure of valves. Install bypass valve beside the sluice valve, while valve caliber DN≥350mm, and select the caliber of bypass valve as one-tenth of normal caliber; adopt worm drive as caliber DN≥400mm. But better to choose electrically operated valve in the head station, 13 / 60 Shenyang Research Institute Of Environmental Sciences while DV≥400mm, use butterfly valve on the buried pipe. (3) Compensator Selection According to the designation, must install compensating mechanism on the pipe joint, when cannot meet requirement from stress. This project selects buried corrugated expansion joint, and stress level P = 2.5 MPa. (4) Water Pump Selection Use energy-saving water pump as the station recycle pump, but will use double-suction pump if it is a large station. Prepare a spare pump beside the working pump.

Same as other heat interchangers, although the plate heat interchanger has a high efficiency, the narrow access, easy to scale formation are still problems, under this circumstance, the vibration spiral coil heat interchanger is a good option. The quantity of heat interchangers depends on the scope of service area, from 2 to 3 sets, monitor stress set to 1.6 MPa, shell stress set to 0.8 MPa. 2.5.6 Antisepsis and Heat Insulation for Pipes Use compounded polyurethane insulating tube for the buried hot water pipe, thickness of insulation is δ=5cm, other technique requirements correspond the CJ/T114-2000 standards. Adopt uncompensated layout for the buried pipe, install minimum compensators, as lack of stress. Adopt steel wrapped steel insulating tube for the buried steam pipe, internal fixation, install external pressure compensator or corrugated expansion joint, heat insulation structured by heat 14 / 60 Shenyang Research Institute Of Environmental Sciences preservation level, air layer and internal reflection level, and require the working temperature of outer steel lagging T＜60oC. 2.5.7 Designation for Power Supply The load of supplied power is second class in all the stations, and the voltage grade is 0.4 KV. Get ready for two recycle pumps, one reserved; two make-up water constant pressure pump, one reserved; others correspond illumination load. Set up one low-tension distribution room with four or five GGD2 distribution cabinets, soft boot recycle pump, one operating two units, adopt variable-frequency control make-up water constant pressure pump. 2.5.8 Automatic Monitoring Designation Adopt Smart Elbow flowmeter monitoring system, it has function as simultaneously collect and display multiparameter, such as, flow rate, pressure, temperature, and also provide temperature compensation and accumulation to the flow rate, carry out communication through own RS-485 serial communication interface. The heat exchange station detecting parameters are: flow rate of primary and secondary network pipes, instantaneous values of pressure and temperature, and accumulated flow rate. Carry out online monitoring for those heat exchange station parameters through communication network, and provide these data to the central control room. Adopt GPRS wireless data communication, and using seamless ground connection of mobile telecommunication network. Compare with the wire communication, it has advantages as less one-time investment, reliable operation, less maintenance, low operational costs, charge of data flow rate, good expandability. Install GPRS modem in all heat exchange stations, transmit collected signals to the host computer. The selection of primary meter has significant impact on the control level of the network, especially the flow meter and thermometer, which parameter will be considered to the metric calculation, use meter with high class accuracy for economic 15 / 60 Shenyang Research Institute Of Environmental Sciences costs.

Prediction and Evaluation on Environmental Impact 7.1 Construction Period (1) Prediction and Evaluation on Environmental Impact of Noise Table 7-1 Prediction Result of Construction Noise Distance Standard dB(A) Instantaneous Equivalent Standards Constructio Prediction Distance Equipment Value Sound in n Stage Value Standards(m) (5m away Level Constructio 41 / 60 Shenyang Research Institute Of Environmental Sciences from source) n area （Leq） Tipper 85 76.0 75 Shovel 86 77.0 75 Loader Earthwork 83.3 13 Bulldozer 89 80.0 75 Excavating 85 76.0 75 Machine Land 87 78.0 75 Scraper Air Groundwork 92 83.0 88.2 75 23 Compressor Air Pick 95 86.0 75 Vibrating 79 70.0 70 Rod Structure 86.0 9 Electric 95 86.0 70 Saw Since the construction will be carried out during the daytime and stop working during the nighttime, there is only few impact on the residents around. (2) Prediction and Evaluation on Environmental Impact of Exhaust Gas Since the exposed ground can be blew dust under a dry windy weather, the pipeline excavation easily causes raising dust. Additionally, the transportation is also a source of raising dust during the construction period. According to the analogical prediction, the raising dust will make pollution within the downwind 100m area. Under this circumstance, efficiently watering must be made during construction, and build up bounding walls also need to be adopted for prevent the raising dust influence the environmental air quality. (3) Prediction and Evaluation on Environmental Impact of Sewage a. Domestic Sewage The domestic sewage discharged from construction is negligible, and also the construction places are dispersed, so the domestic sewage will not form a surface runoff, 42 / 60 Shenyang Research Institute Of Environmental Sciences most of it will be naturally evaporated, and will not make a significant influence on the surface water and groundwater quality. b. Construction Sewage The construction sewage mainly from few pipe washing and it mainly contains SS. This kind of sewage will enter into sedimentary facies, because of the gravity power and as well as sorption, it will rarely harm the surface water and ground water. (4) Prediction and Evaluation on Environmental Impact of Solid Trash The construction solid trash is mainly from surflaes after pipe laying, beside this, heat exchange station building up contributes some trash too. Hereinto, around 40 thousand tons surflaes will be produced, and heat exchange station building up gives approximately 4,000t trash. Produced solid trash will be filled in the appointed construction trash landfill field, and has not significant influence on the environment. (5) Prediction and Evaluation of Environmental Impact on City Society and Landscape a. Impact of Construction Activities on City Landscape. The pipeline laying and excavation damages road and impacts city landscape; improper earthwork stacking protection and uncovered construction machinery on the middle of road also impact city appearance. b. Impact of Construction Activities on Residents’ Life. The Construction area on the road or in the residential district all can make inconvenience for residents walk around; noise from construction equipments, the raising dust, sewage, surflaes and the stacking and transportation of construction trash will also influence residents’ daily life. c. Impact of Construction Activities on Transportation 43 / 60 Shenyang Research Institute Of Environmental Sciences The HNP pipeline crosses many traffic hinges, which is difficult to arrange traffic running, the improper arrangement of dump truck working time will increase transport flow rate and cause the traffic congestion. d. Impact of Construction Activities on Urban Virescence During the construction of pipeline laying, taking up greenbelt for stacking and cutting down trees are unavoidable, which will affect the virescence. The above points listed the impacts on the environment during the construction period, but those are temporary impacts, and will disappear along with the construction finishing. (6) Prediction and Evaluation of Impact on Urban Ecological Environment The HNP layout along with the city streets, damages the city earth surface protective layer, temporarily changes the hard cover of earth surface; the temporary surflaes causes raising dust after wind blow, which impact the life of residents and company employees lived around; and the temporary surflaes on the side of road could cause soil and water loss after the rain. But since the construction will be carried out fragmentally, the influenced period is short, and disappear along with the construction finishing, the earth surface will be recovered too. There are two parts of surflaes, one is transpositional earthwork from pipeline laying; and the other part is the remainder earthwork after backfill, which caused by the loose soil after excavation, although the standards is “backfill soil must have 0.3m higher than the ground level”. After a primary calculation, the volume of surflaes from pipeline laying is 4.7×104m3, which should be sent to the appointed construction trash stacking point. The area being taken up during the construction period are all temporarily used, do not change the original soil function basically, after construction finishing, most of it will be recovered. Once the construction has been done, backfill pipeline, clean up working field, resume ground feature and the original soil function. 44 / 60 Shenyang Research Institute Of Environmental Sciences 7.2 Operation Period 7.2.1 Prediction and Evaluation of Noise Environmental Impact The main noise source during this period is from varies valves, electric equipments and automatic control system in the heat exchange stations.

And the composed noise on the 5m away from heat 46 / 60 Shenyang Research Institute Of Environmental Sciences exchange station nearly equivalent to the background value, so the heat exchange station noise will not affect the life of residents nearby. 7.2.2 Prediction and Evaluation on Environmental Impact of Vibration Table 7-4 Vibration Strength of Equipment Rooms Unit: Hz Pollution Source Leq L10 L50 L90 Standards heat exchange 56.2 53.3 50 48.9 70/67 station As shown in the above table, the vibration prediction result reaches the standards, and according to the this HNP planned designation, all the heat exchange stations are single structured, and located above the ground, the nearest distance is 5m away from residential buildings. Because the vibration is transmitted through solid medium, after adopt the shock-absorption application and keep 5m distance, the impact is not significant. 7.2.3 Prediction and Evaluation on Environmental Impact of Sewage The sewage from water softening instrument and domestic sewage from employees are the main parts of sewage from HNP operation period. Those sewage will be discharged to ShenYang Kangping Sewage Treatment Plant, and will not affect the quality of local surface water and groundwater. Table 7-5 Discharge Status of Water Pollution CODcr NH3-N SS Pollution Factors mg/l t/a mg/l t/a mg/l t/a Produce Demineralized water 20 0.02 — — 30 0.15 1000t/a Domestic Sewage 300 0.36 20 0.02 200 0.24 1200 t/a Discharge 2200 t/a 281 0.38 20 0.02 182 0.39 Standard Value 300 — 30 — 300 — 47 / 60 Shenyang Research Institute Of Environmental Sciences 7.2.4 Prediction and Evaluation on Environmental Impact of Solid Trash During the operation period, the main solid trash is from employees’ living garbage. The number of management and maintenance people will around 96 for the daily operation, according to the analogical prediction, the total living garbage produced during this period will be 28t/a. The living garbage will be gathered collectively, packed properly, and then it is sent to sanitation agency for bio-safety disposal, which will not have a significant impact on the environment. 7.2.5 Environmental Risk Analysis of the HNP Engineering Accident Through an analogical investigation, the potential accident risks of pipeline mostly fall into the following two categories: (1) Natural factors caused pipeline fracture, such as flood, earthquake, and pipeline corrosion and perforation, etc.(i.e. landslide, collapse, sink, etc.) (2) Human activities caused pipeline breakage, for example, misoperation. Although the HNP selected the seamless steel pipe with better compression resistance and imputrescibility, the above reasons could cause dropping or accident. Under an accident controlled within 1 hour, the maximum volume of discharged liquid will be 4,200m3. Since only Ammonia Nitrogen, iron, and manganese in the delivered water quality exceed the Groundwater III grate standards, and other water quality indexes reached the standards, the leak has no significant impact to the soil and groundwater. In addition, the epithelial layer of pipe was laid more than 2m under the road surface, after pipeline laying, ground surface is recovered by hard coverage, the accident leak do not damage ground surface and roadbed. 48 / 60 Shenyang Research Institute Of Environmental Sciences 8. Strategies and Measures for Pollution Prevention 8.1 Construction Period 8.1.1 Construction Noise The construction noise is mainly from construction equipments and vehicles, such as excavators, mixers, and trucks, etc. The construction company must operate correspond with considered: (1) Rational construction working time, 22:00 -6:00 is forbidden to construction; (2) Reinforce construction management; arrange working time in reason, in noise-sensitive area with centralized buildings, construction makes noise is forbidden at night; needs continuously construction under special circumstance, must have approval from relative department, and adopt measures, such as install sound insulation walls, or sound absorption barriers. (3) The entrance for transport vehicles must be located on the side apart from resident districts. (4) Try to use ready-mixed concrete, instead of keeping mixers within construction site. (5) Reinforce the management and channelization, try to reduce vehicle quantity and traffic flow rate, and control the horning. (6) Within the area with centralized residential districts, must install 3-4m height sound insulation walls or sound absorption barriers. (7) The period of mid-year examination and university entrance examination is forbidden to construction. 8.1.2 Raising Dust (1) The construction is easy to make powder pollution, construction company should strengthen the site management, achieve civilized construction; watering site is the efficient measure to control the raising dust. 49 / 60 Shenyang Research Institute Of Environmental Sciences Table 8-1 Assessment of Dust Suppression by Watering Distance from Construction Site（m） 5 20 50 100 TSP Hourly Non-watering 10.14 2.89 1.15 0.86 Concentration Watering 2.01 1.40 0.67 0.60 （mg/m3） (2) The height of placed bounding walls cannot be lower than 1.8m in the construction digging area. Main road must be covered by hard coverage and keep it clean. (3) Must cover dust screen(Fabric) for the construct surflaes, sand and other materials, which is easy to raise dust, and as well as frequently watering to keep ground wet, avoid dust pollution (4) Surflaes and construction trash must be cleaned up and delivered in time, and cover or solidify for the centralized stacking stuff. (5) The vehicle for transport surflaes or construct trash cannot be overfilled, with sealed coverage, and cannot make discharge or leakage on the way. The vehicle must be washed before leaves the construction site, cannot bring mud to the road. (6) Concrete components must be purchased in advance, avoid making powder pollution during construction. If the mixture need to be made in the construction site, try to keep the mortar and concrete no splash and no leak. (7) The transportation vehicles and other varies construction equipments should use low sulphur gas or diesel. Vehicle exhausted gas must meet the requirement of standards. (8) Cement and Lime should be kept in the warehouse and strictly covered. (9) Try to be a civilized construction, rational arrangement for operation process, reduce repeated removal of materials, avoid unnecessary raising dust. 8.1.3 Sewage Since the volume of sewage discharged during construction period is not big, and no toxicant items contained, the strengthen management will make this do not affect the environment too much. The following measures could be adopted: 50 / 60 Shenyang Research Institute Of Environmental Sciences (1) The construction company can draw an organizational design for the sewage discharge, strictly prohibit the sewage discharged without control, which will pollute the road and neighborhood environment. (2) Temporary sedimentation sunk need to be set up, the rain with mud and slurry has to be deposited before discharge. (3) Domestic sewage from employees is discharged into the city sewage conduit after being treated through septic tank. 8.1.4 Solid Trash (1) Construction company has to sign an agreement with Shenyang Environmental Hygiene Management Department on the treatment of surflaes. (2) Construction company needs to appoint a responsible person to manage the surflaes produced in the construction. The transportation and treatment must followed the stated time, place and route. (3) Living garbage from employees need to be gathered collectively, stored properly, and sent to the sanitation agency for bio-safety treatment. 8.1.5 Hazardous wastes disposal measurement (small boiler rooms containing asbestos): 1． The operating personnel should be examined to meet the protection requirements, and then to be allowed to attend disassembly. 2． The warning sign should be set on the construction site. 3． Watering before disassemble. 4． The disposal workers should wear dust mask and protective clothing before starting work. 5． Drawing up a specific plan to remove it with overall stripping method. 6． The safe fence should be used on the operating spot. No irrelevant personnel entry. The professional should be appointed to direct on the site. 7． The disassembled asbestos should be collected by sealable packing bag, then to be put into the specific asbestos cement sealable tank, casting cement, sealing cement tank, and then to be buried deeply for permanent disposal at hazardous wastes landfill site which has the qualification certificate. Shenyang Zhenxing Solid Waste Disposal Co., Ltd. will be responsible for collecting and disposal. The company has the qualification of hazardous wastes disposal. The asbestos found 51 / 60 Shenyang Research Institute Of Environmental Sciences during the disassembling process in other projects would be collected and disposed by Shenyang Zhenxing Solid Waste Disposal Co., Ltd. as well.

Aggregate 90 583461 2033134.49 .87 49 8.1.6 Impact on Urban Society and Landscape (1) Well prepared before the construction starts, carefully investigate all the related underground tube lines, such as power supply, communication and water supply/discharge pipelines. Cooperating with relevant departments for dismantlement or removal plan in advance, prepared for varies emergencies, ensure the tube lines cutting down will not affect the normal supply of water, electricity, gas, and communication connection for the area along the construction line, and keep the social life under a normal status. (2) In order to ensure the construction in a good order, and minimum the impact to the residents normal life and transportation neighborhood, negotiate with the local traffic management department, have a proper planning for the traffic diverting during construction period, uniformly arrange the drive route of construction equipments and transportation vehicles, reduce the traffic flow rate on the road of construction, which can prevent the traffic jam. (3) The construction company needs meet the requirement of Policy>, apply for the Shenyang Bureau of Parks approval for greenbelt taking up, cutting down or replanting trees before construct. Try to adopt temporary virescence measure in the construction site, and clean up the site, recover the greenbelt on the finishing of construction. (4) Under the circumstance of farmland acquisition, Construction Company needs to publish the acquisition scope in time, make compensation of acquisition plan, and fulfill the compensation fund. 57 / 60 Shenyang Research Institute Of Environmental Sciences The system of compensation to cultivated land to be occupied is one of the most important legal measures for protect the farmland dynamic balance, which is calculated according to the actual area of farmland acquired, reclaim the same quantity and quality farmland as the acquired farmland; under the circumstance for lack of ability of reclamation or for failure to meet the required reclamation, land reclamation fees shall be paid, for use in land reclamation. Keep the farmland dynamic balance is the legal duty of the company or individual. 8.1.7 Impact on Urban Ecological Environment (1) Select construction time rationally, avoid the windy and rainy seasons, those could reduce impact of the soil and water loss. (2) During the pipeline excavation, the construction must be standardized on stratified excavation and stacking, laying pipeline at the same time as excavated, try to reduce the temporary earthwork heaped. The produced temporary surflaes cannot be heaped causally.

In Europe, there is wide application of the small heat exchanger equipment for household or building blocks, the water pump maximum sound pressure standards <70dB(A), and some model of the water pump satisfy the 1 grade of Environmental Quality Standards (GB3096-2008)>, which is acoustic environment (residential house)<50dB(A). The water pump is sealed rotor mode, the water pump and electric machine forms a whole, no axial seal, only has two sealing gaskets, and the axletree is lubricated using the liquid delivered by pump. The sound pressure is gradient depression, under the 3 grade rotate speed. B. Add soft joint and insert vibration absorber into bottom of pump Avoid the vibration comes from the pump working, which may impact the pipeline, this makes the system operated more reliable and comfortable. C. Use tiny drag slow shut check valves Install this valve on the water outlet, in order to cut down the return of medium, avoid devastating water hammer, the rubber buffer smoothly switch on/off, vibration-free, and noise free. D. Primary compensate secondary technology Compensate the secondary network using the primary network return water, saves the 61 / 60 Shenyang Research Institute Of Environmental Sciences water replenishing pump, and one noise source is eliminated. E. Exterior covered with protection cover, and interior laid with sound insulation sheet The exterior cover is entirely sealed iron with plastic spray, except the exterior connecting pipe, all the operation and indicator meter are running under the protect cover; the interior laid sound insulation sheet is foam board, and it can absorb noise and vibration efficiently, and also it has heat preservation function. After adopt those above measures, the building heat exchange stations has no significant impact on the surrounding environment. 8.2.7 Sewage (1) The sewage from water softening instrument and domestic sewage from employees are the main parts of sewage from HNP operation period. That sewage will be discharged to ShenYang Kangping Sewage Treatment Plant, and will not affect the quality of local surface water and groundwater. (2) Must adopt seepage prevention treatment for sewage conduit, in order to prevent the possibility of sewage leakage pollutes groundwater. 8.2.8 Solid Trash Living garbage from employees is the main part of solid trash during the operation period. It need to be gathered collectively, stored properly, and sent to the sanitation agency for bio-safety treatment. 9 Overall Control 9.1 Factors According to the provision of 62 / 60 Shenyang Research Institute Of Environmental Sciences Temporary Provision on Overall Pollution Discharging Control>, the factors of the overall control in this project are: CODC r and NH3-N. 9.2 Indicators The overall control indicators for the discharged CODC r and NH3-N in this project are: 0.38t/a and 0.02t/a. 9.3 Regional Reduction After the Heating Network implementation, 94 small boiler rooms will be eliminated, and 95 chimneys will be dismantled; in addition, 40 sets of 7MW hot water boilers are not going to be built.

Proposals Comparison 12.1. Proposals Comparison on Thermal Medium Parameters According to the regulation of section 4.2.2 article 1 of the Proposal 1: Supply water and return water temperature of the primary network is 130/70℃ A. The popular supply water temperature is 130℃, although it is 10℃ higher than proposal 2, there are many successful applications domestically with this sort of parameter, which adopts uncompensated laying method, thereafter, this project can take full advantage of this parameter and adopts advanced direct-buried laying technology, to save the costs of compensator and anchor block. Meanwhile, since every compensator is a future fault point during the network operating, this enable the heat supply system has a safe and reliable operation. B. Since the general prefabricated heat preservation pipe from some domestic qualified prefabricated heat preservation pipe manufacturer has temperature resistance of 140℃. Thereafter, this parameter can use general prefabricated heat preservation pipe, 70 / 60 Shenyang Research Institute Of Environmental Sciences without increase pipe heat preservation expenditure. C. Compare with proposal 2, this parameter could reduce the pipeline caliber and flow rate, which holds low expenditure of pipeline primary investment and operation electricity. D. Compare with proposal 2, the parameter could reduce the heat exchange area from each heat interchanger. E. The disadvantage is the price of pipeline heat preservation is slightly higher than proposal 2, and the primary network pipeline stress with this uncompensated direct-buried laying is bigger than proposal 2. Proposal 2: Supply water and return water temperature of the primary network is 120/70℃ A. Since the supply water temperature is lower, general prefabricated heat preservation pipe can satisfy its requirement of heat preservation, which is propitious to extend its usage life, and with low heat preservation cost, it saves the heat preservation expenditure for this pipeline network.。 B. The pipeline laying method is propitious to the uncompensated mode, which can save the costs of compensator and anchor block. Meanwhile, since every compensator is a future fault point during the network operating, this enable the heat supply system has a safe and reliable operation. C. The supply water temperature is lower than proposal 1, the temperature difference is smaller, and the system circular flow is larger. And since the primary network pipe caliber and flow is bigger than the proposal 1, thereafter, the expenditures of primary network first investment and recycle pump electricity during operating period is larger than proposal 1. D. Compare with proposal 1, the average temperature difference of each heat 71 / 60 Shenyang Research Institute Of Environmental Sciences interchanger reduced 12.32%. Result of the proposal comparison: The above qualitative analysis stated and compared the advantages and disadvantages of these two proposals, at the same time, as considering this project is joint network with primary and secondary stages, the design parameters shall be integrated, moreover, the design parameter of this project primary stage is 130℃. After the proposals comparison, the supply and return water of primary network uses 130/70℃ from proposal 1. And the supply and return water temperature of this secondary hot water network shall be the same as the first stage project, with radiator heating is 80/55℃, and floor radiation heating is 60/50℃. To sum up, choose proposal 1 as this project thermal medium parameter. 12.2 Comparative Analysis of the Project Proposal with/without Operating Project 12.2.1 Project Energy Efficiency Comparison with/without Operating project After the implementation of this project, central heating building area can reach to 3 million m2, and by replacing the scattered small boiler rooms with the central heat and power cogeneration, can achieve great energy conservation.
