This project has a total investment of 39 million yuan and is located in the National Jinggangshan Economic and Technological Development Zone. The annual output of this project is 5000t of polyamide (including 1000t each of ketimine polyamide and solvent-based polyamide, 3000t of high-solid-content polyamide), 1000t each of modified amine and naphthalenesulfonic acid amine, and 3000t of polyether amine. The project operates 300 days a year, and the main raw and auxiliary materials can be purchased from the market.

II. Overview of the Potential Environmental Impacts of the Construction Project
The main air pollution sources of this project are the flue gas from the heat transfer oil furnace. Water pollution sources mainly include wastewater from production process washing, flue gas scrubbing water, ground washing wastewater, and domestic sewage. Solid waste mainly includes filter residue, waste kaolin, water treatment sludge, coal ash, desulfurization slag, and domestic garbage. Noise mainly comes from the noise generated by equipment such as blowers and induced draft fans.
III. Key Points of Countermeasures and Measures to Prevent or Reduce Adverse Environmental Impacts
1. The flue gas from the heat transfer oil furnace is treated by cyclone dust removal + hemp stone water film cyclone dust removal and desulfurization device, and then discharged through a chimney 30m high. The treated waste gas is discharged through the chimney to meet the standards. The impact of external waste gas on the environment is relatively small.
2. Wastewater. After neutralization + flocculation sedimentation + biological contact oxidation treatment, the production wastewater is discharged through the sewage pipeline to meet the standards. Domestic sewage is discharged through the sewage pipeline to meet the standards after septic tank + biological contact oxidation treatment. The impact of wastewater on the receiving water body is relatively small.
3. Solid waste. According to the current solid waste disposal plan, filter residue, waste kaolin, and water treatment sludge are all hazardous waste and are sent to qualified units for treatment; coal ash is used for road paving; desulfurization slag is sold to building material factories for comprehensive utilization; and domestic garbage is regularly sent to landfills for landfill.
4. Noise. To reduce the impact of noise, firstly, control is implemented at the source, and low-noise equipment is selected as much as possible in the design; secondly, comprehensive noise reduction measures for workshop ventilation, air conditioning, and exhaust systems are adopted; and finally, building sound insulation is used.
5. To prevent the infiltration of wastewater from the construction project from polluting groundwater, the workshop floor (including drainage ditches) is designed to be corrosion-resistant and leak-proof, and wastewater leakage from the workshop is collected through drainage ditches and pumped into the wastewater treatment plant for treatment; to prevent the infiltration of materials and wastewater from causing groundwater pollution.
6. The environmental risks in the production process mainly include the environmental risks of chemical raw and auxiliary materials such as xylene, methanol, sulfuric acid, and ammonia during storage and use, as well as the risk of accidental discharge when wastewater and waste gas pollution control facilities fail, and the risk of rupture of dedicated drainage pipes. In order to prevent material leakage risks, dykes and ditches are set up in the storage area to receive them.
IV. Key Points of the Environmental Impact Assessment Conclusion Put Forward in the Environmental Impact Report
Under the pollution control measures proposed in the report, various pollutants can be discharged up to standards, and their impact can be accepted by the environment. As long as the design scheme of the construction project is effectively implemented to meet the design requirements, and the environmental protection measures required in the environmental impact report are strictly implemented during the construction and operation periods, the construction project will be guaranteed in terms of environmental protection. From the perspective of environmental protection, the proposed project is feasible.
