10 Conclusions and recommendations
10.1Conclusion
10.1.1III Simultaneous implementation
Hubei Tri-Ring Metalforming Equipment Co.,Ltd Large and Precision CNC Forging Machine Tool Development Base Construction Project (Phase II) carried out environmental impact assessment in accordance with the provisions of the the People's Republic of China Environmental Protection Law and the Measures for the Administration of Environmental Protection of Construction Projects, and implemented the "three simultaneous" system of simultaneous design, simultaneous construction and simultaneous production of environmental protection facilities and main projects.
10.1.2Working condition conclusion
During the acceptance and monitoring of Hubei Tri-Ring Metalforming Equipment Co.,Ltd's large and precision numerical control forging machine tool development base construction project (phase ii), the production load exceeded 75%, the monitoring results are representative.
10.1.3Exhaust emission monitoring conclusions
The waste gas produced in the second phase of the project is mainly dust produced by polishing and derusting and paint spraying to produce benzene, toluene and xylene. The exhaust gas monitoring results show that the dust at the outlet of the dust removal equipment and the concentrations of benzene, toluene and xylene at the outlet of the paint mist purification device are in line with the requirements.Integrated Emission Standard of Air Pollutants (GB16297-19961) Requirements in Class II standard for newly-built pollution source.
Set 4 around the factory boundaryMonitoring points, monitoring 2 days, 4 times a day monitoring. From the monitoring results, it can be seen that the dust at each monitoring point is lowerIntegrated Emission Standard of Air Pollutants (GB16297-19962) Standard in Class II Standard of New Pollution SourceLimits.
10.1.4Conclusion of wastewater discharge monitoring
Phase II ProjectThe resulting wastewater is divided into production wastewater and domestic wastewater,Production wastewater and domestic sewage are pre-treated in the grease trap and then enter the first-stage sewage treatment station for centralized treatment, and then discharged into the municipal sewage pipe network of the park and into the Shannan Sewage Treatment Plant for treatment. From the monitoring results of wastewaterGeneral waste water outletMedium PHChemical Oxygen DemandThe discharge concentrations of suspended solids, ammonia nitrogen, petroleum and five-day biochemical oxygen demand are in line with the Integrated Wastewater Discharge Standard (GB8978-1996).Requirements in the third-level standard.
10.1.5Noise Monitoring Conclusion at Boundary
Set 4 at the boundary of the plant1 monitoring point and 1 monitoring point for each of the two sensitive points to monitor the equivalent continuous sound level A, once in day and night for 2 days. From the monitoring results, it can be seen that the daytime and nighttime sound level values of each monitoring point of noise at the factory boundary meet the requirements of Class 3 and Class 4 of the Emission Standard for Environmental Noise at the Boundary of Industrial Enterprises (GB12348-2008). The daytime and nighttime sound levels of the noise at the two sensitive points are in line with the requirements of Class 2 of the Emission Standard for Environmental Noise at the Boundary of Industrial Enterprises (GB12348-2008).
10.1.6Solid waste investigation conclusion
The solid waste of the project mainly includes hazardous waste and general waste. The general waste is mainlyScrap scrap, scrap iron, waste packaging and dust collected from welding and grinding processes, as well as domestic waste. Hazardous wastes mainly include waste emulsion, waste paint residue, waste activated carbon, waste paint bucket, etc.
produced in the production processWaste scrap, scrap iron, waste packaging and dust collected from welding and grinding processesCentralized collection and sale; household waste is handed over to the sanitation department for regular removal.
Waste emulsion is temporarily stored in a special tank, waste paint residue, waste activated carbon, waste paint bucket, waste oil, etc.Hazardous waste is centrally stored in the temporary storage of hazardous waste, and is handed over to Hubei Tianyin Hazardous Waste Centralized Disposal Co., Ltd. and Huanggang Tianyi Environmental Protection Technology Co., Ltd., which have corresponding treatment qualifications, for centralized treatment.
10.1.7Total amount control conclusion
The discharge amount of waste water pollutants from the project is: chemical oxygen demand 0.25t/a, ammonia nitrogen 0.014t/a, which meets the requirements of total control index expected by EIA (COD≤ 8.035t/a, ammonia nitrogen ≤ 0.203t/a).
The discharge amount of main pollutants of the project is 0.3t/a and xylene is 0.024t/a, which meets the requirements of the total amount control index expected to be approved (total amount of benzene, xylene and toluene ≤ 1.4t/a, dust ≤ 1.11t/a).
10.2Recommendations
(1) Further strengthen the environmental management of environmental protection facilities and the production process, prevent "running, emitting, dripping, and leaking", eliminate environmental accidents, improve the operating efficiency of environmental protection facilities, and ensure long-term and stable discharge of pollutants.
(2) Strictly follow the safety production operation specifications of the enterprise, strengthen the constraints on related parties, and ensure environmental safety.
(3) Strengthen the management of the production environment of the factory area, strengthen the greening of the factory area, and make the factory area clean and orderly.
