 3、 Overview of the potential impact of construction projects on the environment

(1) Waste gas

The waste gas generated by the project mainly includes methanol, ethylene oxide, propylene oxide, ammonia, etc. According to the prediction, under normal operating conditions, the exhaust gas from the project has little impact on the surrounding atmospheric environment and can meet the requirements for functional zone classification.

(2) Wastewater: The wastewater of this project mainly includes process wastewater, equipment cleaning wastewater, ground mopping wastewater, and domestic wastewater. The wastewater from this project is collected and treated by the company's wastewater station before being included in the sewage pipeline network. It has little impact on the surrounding water environment.

(3) Noise: The main noise generated after the implementation of this project is the operating noise of equipment such as reactors, vacuum units, delivery pumps, and fans. The noise source intensity is between 65 and 88dB. After the noise is soundproofed, shielded, and attenuated by the factory building and walls, it can effectively reduce the noise intensity and has no significant impact on the surrounding environment. It is expected that after the project is launched, the environmental quality status around the company's factory boundary can still meet the Class 3 standard in the "Industrial Enterprise Boundary Environmental Noise Emission Standard" (GB12348-2008), and after adding background values, it can meet the Class 3 standard in the "Acoustic Environment Quality Standard" (GB3096-2008), with little impact on the surrounding acoustic environment quality.

(4) Solid waste: The solid waste of this project mainly includes filter residue, waste catalyst, wastewater treatment sludge, general waste packaging materials, toxic and harmful waste packaging materials, household waste, etc. Filter residue, waste catalysts, wastewater treatment sludge, toxic and harmful waste packaging materials, etc. are classified as hazardous waste and are entrusted to qualified units for disposal; Comprehensive utilization of general waste packaging materials; Domestic waste is regularly entrusted for unified transportation.

4、 Key points of countermeasures and measures to prevent or mitigate adverse environmental impacts

(1) Waste gas

The polyether amine raw materials, methanol polyether and propylene glycol polyether, are produced in conjunction with the original approved special polyether production line (Class A workshop 1). The exhaust gases, such as ethylene oxide, propylene oxide, and methanol, are discharged from high altitude after being treated with "secondary water spray+alkali spray" at the existing Class A workshop 1 exhaust gas treatment facility to meet the standards; The ammonia gas generated from the depressurization and degassing of the polyether amine production line is discharged at high altitude after being treated with "first stage falling film+third stage water absorption+acid absorption" to meet the standards; The wastewater generated from the depressurization dehydration of the polyether amine production line and the acid absorption wastewater are treated with "neutralization+ammonia evaporation+secondary falling film" to produce ammonia gas, which is then "washed" to meet the standards before being discharged at high altitude.

(2) Wastewater

A. Strictly implement the principle of "separation of clean and dirty water", and set up sewage drainage pipes and rainwater drainage networks.

B. The comprehensive wastewater of this project will be treated by the existing sewage station through "physicochemical+two-stage biochemical" treatment and will be included in the Shangyu Sewage Treatment Plant for treatment.

(3) Solid waste

A. Solid waste classification, collection, and stacking. Establish a unified solid waste classification system and a unified stacking site, which requires rain and leakage prevention measures.

B. Filter residue, waste catalysts, wastewater treatment sludge, toxic and harmful waste packaging materials, etc. are classified as hazardous waste and are entrusted to qualified units for disposal; Comprehensive utilization of general waste packaging materials; Domestic waste is regularly entrusted for unified transportation.

(4) Noise

Select low-noise equipment models, arrange noise generating equipment reasonably, place high noise sources, etc. on the side away from the factory boundary, and do a good job in basic vibration reduction; Install silencers at the inlet and outlet of the fan; Strengthen the maintenance and upkeep of mechanical equipment.

5、 Key points of environmental impact assessment conclusion

The project site is located at No. 8, Weiqi East Road, Shangyu Economic and Technological Development Zone, Hangzhou Bay. The infrastructure is relatively complete and the environmental conditions are relatively favorable, which conforms to the overall planning of Shangyu District and the national industrial policy. The production process of the project is progressiveness, and the equipment technology can basically meet the requirements of clean production. After the implementation of various pollution prevention measures proposed in this environmental assessment, the pollutants can reach the standard of discharge, in line with the principle of total amount control. After the implementation of the project, the contribution of various pollutants to the surrounding environment after reaching the standard of discharge after treatment is small, and the local environmental quality can still maintain the status quo.

Therefore, from an environmental perspective, as long as the various governance measures proposed in this environmental assessment are implemented, the "three simultaneities" system is strictly implemented, the pollutant discharge meets standards, and environmental management is strengthened, the project is feasible to be implemented within the selected plant site.
