2.3 Major sources of pollution and governance 2.3.1 Waste water The project wastewater includes landfill leachate, domestic sewage, chemical water plant wastewater, boiler blowdown, flushing water, etc. The amount of landfill leachate produced by the project is designed according to 30% of the daily waste. The daily waste disposal capacity of this project is 25 tons, and the daily treatment capacity of the designed leachate is 8 tons. Domestic sewage is produced in small quantities. After pretreatment in the septic tank, it enters the landfill leachate collection pit through the underground pipe network and finally enters the landfill leachate treatment station. The wastewater in the water treatment plant, the boiler sewage and the flushing water are all fixed sewage. The fixed sewage enters the slag pool from the ditches in the incineration plant, and the sediment waste generated in the slag pool enters the solid waste treatment system and is temporarily transported and landfilled. The internal ditch enters the landfill leachate treatment station; the water treated by the landfill leachate treatment station is used for the incinerator slag cooling. The rainwater in the plant area is directly collected through the rainwater pipe network in the plant area. The project has completed the treatment of a sewage treatment station with a scale of 8m3/d. The sewage treatment station adopts the treatment process of biochemical + ultrafiltration (UF) + nanofiltration (NF) + reverse osmosis. The equipment of the system is mainly non-standard products, pumps, pipes and membranes are purchased products, and the complete sets of equipment are manufactured by Zhejiang Tailai Environmental Protection Technology Co., Ltd.

2.3.2 Exhaust gas The waste gas generated by the project mainly includes incineration flue gas (main pollution factor is

SO2, soot, nitrogen oxides, HC1, heavy metals, dioxins, etc.), and malodorous gases generated during garbage storage pits, sewage treatment stations, and garbage trucks. The project incineration flue gas treatment process is treated by a semi-dry reaction tower + activated carbon adsorption + bag filter, and the flue gas is discharged after being treated at a height of 25 meters. After the flue gas comes out of the waste heat boiler, it is contacted with the sprayed alkali solution in the deacidification tower (ie, the semi-dry reaction tower), and the harmful acid gas such as hydrogen chloride and sulfur dioxide in the flue gas is chemically reacted with sodium hydroxide to form harmless. Sodium chloride, sodium sulfate, etc. are deposited on the dust collection port. Thereafter, the flue gas enters the bag filter through the flue and performs the final dust removal and purification treatment. At the same time, an active spraying device is arranged on the flue to inject activated carbon into the flue, so that the activated carbon fully adsorbs harmful substances such as heavy metals and dioxins in the flue gas, and enters the bag filter together with the flue gas, and passes through the filter and passes through the induced draft fan. Delivered to the smoke and discharged to the atmosphere. Exhaust gas treatment system includes flue gas deacidification tower (semi-dry reaction tower), sodium hydroxide solution addition device, activated carbon feeding device, bag filter, fly ash temporary storage device, compressed air station, induced draft fan, online monitoring device, chimney And the corresponding control equipment. The equipments such as acid tower, lye preparation and bag filter are designed and manufactured by Zhejiang Tailai Environmental Protection Technology Co., Ltd., and the activated carbon feeding device is designed by Qingdao Pacific Chemical Equipment Co., Ltd.

2.3.3 noise The noise of the project is mainly the mechanical noise generated by thermal decomposition furnace, waste heat boiler, various auxiliary equipment such as pumps and fans, comprehensive noise such as flow and exhaust of various pipelines. When selecting the equipment for the project, try to use equipment with less noise. The inner wall of the boiler room is lined with sound insulation material, the steam venting tube and the pressure reducing valve are provided with silencer; the interface between the flue and the fan is made of soft joints and heat preservation and reinforcing ribs, primary and secondary fans, emptying, air compressor, etc. The muffler is provided to reduce the influence of the transportation vehicle on the concentrated passage area. The garbage truck does not work at night, and the speed is limited in the noise sensitive area, and the whistle is prohibited. 2.3.4 Solid Waste The solid waste generated by the project mainly includes incinerator slag, fly ash, sludge from sewage treatment and domestic garbage. Among them, fly ash is a hazardous waste. The slag pool is not built in the plant area, and the slag generated by the furnace is directly collected by the sanitation department and transported to the town landfill. The produced fly ash is mixed with a chelating agent + cement + water to form a block. After the fly ash is solidified, it is temporarily stored in a hazardous waste storage warehouse of about 25 square meters on the north side of the plant. It is collected by the sanitation department and transported to the county landfill. Sludge from sewage treatment and domestic garbage from workers shall be disposed of by incineration in this project.

3.11 Solid Waste Survey Results The solid waste generated by the project mainly includes incinerator slag, fly ash, sludge from sewage treatment and domestic garbage of workers. Among them, fly ash is a hazardous waste. The slag pool is not built in the plant area, and the slag generated by the furnace is directly collected by the sanitation department and transported to the town landfill.

The produced fly ash is mixed and stirred by a chelating agent + cement + water to form a block. The fly ash is solidified and stored in the hazardous waste storage warehouse of about 25 square meters on the north side of the plant. It is collected by the sanitation department and transported to the county landfill. The sludge produced by sewage treatment and the domestic garbage of workers shall be incinerated by the incinerator of this project. According to the investigation, the slag has a high water content during the weighing process due to the wet slag method. According to the actual production volume from June to December 2016, the annual production of solid waste is about 1964.2 tons, and the annual output of hazardous waste is about 65 tons.

Note:1. Measured mass concentration (ps): dioxin-like mass concentration measurement (ng/m3) 2. Converted mass concentration (p): 11% oxygen content of dioxins mass concentration (ng/m3)

Actual oxygen volume fraction

3. Toxic equivalent (TEQ) mass concentration: 2,3,7,8-T4CDD toxicity equivalent (TEQ) mass concentration, ng/m3 4. Detection limit: When the measured mass concentration is lower than the detection limit, it is represented by ‘N.D.”, and the calculation of the toxicity equivalent (TEQ) mass concentration is calculated by the 1/2 detection limit. 5. The dioxin concentration in the table is the value under standard conditions, and the sample volume of the exhaust gas sample is 2.34m3. 6. The toxic equivalent factor TEF uses the international toxicity equivalent factor I-TEF.
