10. Conclusions and recommendations

 

10.1 Conclusion

10.1.1 Three simultaneous implementations

Hubei Sanhuan Forging Equipment Co., Ltd. Large-scale, precision CNC forging machine tool development base construction project (second phase) conducted an environmental impact assessment in accordance with the provisions of the "Environmental Protection Law of the People's Republic of China" and "Administrative Measures for Environmental Protection of Construction Projects" The "three simultaneous" system in which facilities and main projects are simultaneously designed, constructed and put into operation at the same time.

10.1.2 Working condition conclusion

During the acceptance monitoring of the construction project of the large-scale, precision CNC forging machine development base (Phase II) of Hubei Sanhuan Forging Equipment Co., Ltd., the production load exceeded 75 %, and the monitoring results were representative.

10.1.3 Exhaust emissions monitoring conclusion

The waste gas generated in the second phase of the project is mainly the dust produced by grinding and derusting and the benzene, toluene and xylene produced by paint spraying. From the monitoring results of exhaust gas, it can be seen that the dust at the outlet of the dust removal equipment and the concentration of benzene, toluene, and xylene at the outlet of the paint mist purification device all meet the requirements of the second level standard of the new pollution source of the "Comprehensive Emission Standards for Air Pollutants" (GB16297-1996 ).

Set up 4 monitoring points around the plant boundary , monitoring 2 days, 4 times a day. From the monitoring results, it can be seen that the dust at each monitoring point is lower than the standard limit in the second level standard of the new pollution source in the Comprehensive Air Pollutant Emission Standard (GB16297-1996 ) .

10.1.4 Wastewater discharge monitoring conclusion

The sewage generated in the second phase of the project is divided into production wastewater and domestic sewage. After being pretreated by the grease trap , the production wastewater and domestic sewage enter the first-stage sewage treatment station for centralized treatment, and then are discharged into the municipal municipal sewage pipe network and into the Shannan sewage treatment plant for treatment . Wastewater is clear from the results of monitoring waste water discharge port of the total in the PH , COD , suspended solids, ammonia nitrogen, petroleum, BOD of the effluent concentration are in line "Integrated wastewater discharge standard" (GB8978-1996) in three The requirements in the standard.

10.1.5 Noise monitoring conclusions at the plant boundary

Set up 4 monitoring points at the plant boundary and 1 monitoring point at each of the two sensitive points to monitor the equivalent continuous A sound level, once for each day and night for 2 days. It can be seen from the monitoring results that the daytime and nighttime sound level values ​​of each monitoring site of noise and noise at the plant boundary meet the requirements of Class 3 and Class 4 standards of "Environmental Noise Emission Standards for Industrial Enterprises at Plant Boundary" (GB12348-2008). The daytime and nighttime sound level values ​​of the noise at the two sensitive points are in compliance with the requirements of the Class 2 standard of "Environmental Noise Emission Standards for Industrial Enterprises' Boundaries" (GB12348-2008).

10.1.6 Conclusion of solid waste investigation

The solid waste of the project mainly includes hazardous waste and general waste. General wastes are mainly waste scraps, scrap iron scraps, waste packaging and welding, dust collected in the grinding process, and domestic garbage. The hazardous wastes are mainly waste emulsion, waste paint residue, waste activated carbon, waste paint buckets, etc.

Waste scraps, scrap iron, waste packaging and dust collected during the welding and grinding processes generated in the production process are collected and sold out; domestic waste is handed over to the sanitation department for regular transportation.

The waste emulsion is temporarily stored in a dedicated tank, and hazardous wastes such as waste paint residues, waste activated carbon, waste paint buckets, and waste oil are stored in the temporary waste storage warehouse, and are handed over to Hubei Tianyin Hazardous Waste Concentration with appropriate disposal qualifications. Disposal Co., Ltd. and Huanggang Tianyi Environmental Protection Technology Co., Ltd. deal with it centrally.

10.1.7 Total control conclusion

The discharge amount of pollutants in the project wastewater is: chemical oxygen demand 0.25t/a, ammonia nitrogen 0.014t/a, which meets the requirements of the EIA total control index (COD≤8.035t/a, ammonia nitrogen≤0.203t/a).

The project's main pollutant discharge amount is: 0.3t/a, xylene 0.024t/a, which meets the expected total control index requirements (total amount of benzene, xylene, toluene ≤1.4t/a, dust ≤1.11t/a ).

10.2 Recommendations

(1) Further strengthen the environmental management of environmental protection facilities and production processes, prevent "running, running, dripping, and leakage", prevent environmental accidents, improve the operating efficiency of environmental protection facilities, and ensure the long-term and stable discharge of pollutants.

 

(2) Strictly follow the enterprise's safety production operation standards, strengthen the constraints on relevant parties, and ensure environmental safety.

(3) Strengthen the management of the production environment of the plant, strengthen the greening of the plant, and make the plant clean and orderly.
