The second public announcement of the environmental impact assessment of the JA, BG-3 and D004-D new product upgrade projects of Chongqing Chunrui Pharmaceutical Chemical Co., Ltd.
In accordance with the "Interim Measures for Public Participation in Environmental Impact Assessment" (Huanfa [2006] No. 28) and the "Notice on Effectively Strengthening Risk Prevention and Strict Environmental Impact Assessment Management" (Huanfa [2012] No. 98) and other relevant regulations, Chongqing The relevant information on the environmental impact assessment of the new product upgrade project of Chunrui Pharmaceutical Chemical Co., Ltd. JA, BG-3 and D004-D will be announced.
1. Project name and project summary.
Project name: JA, BG-3 and D004-D new product upgrade project.
Construction nature: industrial technological transformation.
Construction site: The existing factory area of Chunrui Company, No. 44, Luoxi Road, Luoqi Town, Yubei District, Chongqing.
Construction unit: Chongqing Chunrui Pharmaceutical Chemical Co., Ltd.
Total investment: 1.2 million yuan
Area: 740 m2.
Work system: four shifts and three operations, 240 hours (total 10 days) in JA years; 7200 hours (total 300 days) in BG-3 years; 600 hours (total 25 days) in D004-D years;
Labor quota: No new employees, deployed by existing devices
Construction plan: one year
Main construction content: use the existing plant to carry out technical transformation of equipment, transform 30 equipment (sets) and supporting facilities, construct JA products (4-amino-3-methoxymethyl benzoate), BG-3 products ( Phthaloyl-L-alanyl-L-glutamine) and D004-D (2α-methyl-2β-(1,2,3-triazol-1-yl)methylpenicillin) One production line for sulfone-3α-diphenylmethyl carboxylate, forming an annual production capacity of 10 tons of JA, 50 tons of BG-3 and 20 tons of D004-D. Exhaust gas relies on the company's existing waste gas treatment facilities, and waste water relies on the company's existing sewage treatment facilities.
2. The possible impact of the construction project on the environment and the preventive measures and measures
1, ambient air
Process waste gas pollutants of the project are mainly methanol, toluene, non-methane total hydrocarbons and a small amount of sulfur dioxide and hydrochloric acid mist. JA waste gas mainly contains methanol, toluene and non-methane total hydrocarbons. D004-D waste gas is mainly non-methane total hydrocarbons. After being collected, the existing 2# waste gas treatment facility adopts "PEG-400+sodium carbonate aqueous solution spray + paraffin oil extraction". After treatment, it is discharged by an 18m exhaust cylinder; BG-3 exhaust gas mainly contains methanol, toluene, non-methane total hydrocarbons and a small amount of sulfur dioxide and hydrochloric acid mist. After being collected, the existing 1# exhaust gas treatment facility adopts "PEG-400+ sodium carbonate aqueous solution" After spraying + paraffin oil extraction, it is discharged from a 15m exhaust tube. After the exhaust gas is treated, the concentration of sulfur dioxide, hydrochloric acid mist, methanol, toluene and non-methane total hydrocarbons can meet the corresponding standards of the Chongqing Comprehensive Emission Standard for Air Pollutants (DB50/418-2016), which has little impact on the local atmospheric environment .
2, surface water
Project wastewater is mainly JA centrifugal wastewater, BG-3 condensation wastewater, washing wastewater, absorption wastewater, centrifugal wastewater, D004-D extraction wastewater, washing wastewater, and floor washing wastewater, water ring vacuum wastewater, laboratory wastewater and exhaust gas alkaline washing Wastewater, the main pollutants produced are COD, ammonia nitrogen, SS, nitrobenzenes, anilines, dichloromethane, etc. The wastewater is discharged into the sewage treatment station and treated by the "iron-carbon micro electrolysis + hydrolysis acidification, anaerobic" treatment process Afterwards, it can meet the corresponding limits of the "Discharge Standard of Water Pollutants for the Chemical Synthesis Pharmaceutical Industry" (GB21904-2008). After the technical transformation, the amount of wastewater and pollutant discharge of the whole plant has been reduced, which is conducive to the improvement of the surface water environment.
3. Groundwater
All production equipment areas, tank farms, accident tanks, wastewater collection tanks, etc. adopt anti-seepage and anti-corrosion measures. Sewage pipes and material conveying pipes adopt "visual" design, and cofferdams and fire dikes adopt anti-seepage and anti-corrosion treatments. Under normal circumstances, the impact on the groundwater environment is small.
4. Acoustic environment
The noise of the project mainly comes from the operation noise of production equipment, which is concentrated in the production workshop. The noise source intensity of each equipment is generally small. By rationally arranging the noise source and adopting measures such as equipment shock absorption, sound insulation of the factory building, and greening of the plant week for high-noise equipment, the impact of workshop noise on the acoustic environment can be effectively reduced, and the project plant boundary can reach The "Environmental Noise Emission Standards at the Boundary of Industrial Enterprises" (GB12348-2008) requires category 2 standards, which have less impact on the acoustic environment.
5. Solid waste
Project JA device has sodium sulfate solid residue, waste palladium carbon catalyst, BG-3 device has methanol distillation residue, D004-D device has acetonitrile distillation residue, as well as sewage treatment station sludge, waste solvents from waste gas treatment facilities, waste gloves, cotton yarn, etc. , All belong to hazardous waste, the waste palladium-carbon catalyst is sent to the manufacturer for treatment and then recycled, and other wastes are sent to qualified units for unified disposal and not discharged. No new employees or household wastes will be added to the technological transformation project.
In summary, the solid waste generated during the operation period of the proposed project meets environmental protection requirements after being disposed of and will not have a significant impact on the environment.
6. Environmental risk
The methanol raw materials of the technological transformation project are packed in barrels, and the storage capacity of other liquid raw materials is small, and the whole plant does not constitute a major source of danger. The risk prevention measures adopted are as follows: the installation area is equipped with a dike and a fire dike; the accident pool is equipped with anti-corrosion and anti-seepage measures; the installation area is equipped with a rain and sewage switch valve; an accident pool with an effective volume of 1000m3. The wastewater pipe network is designed for "visualization". With effective and reliable risk prevention measures and emergency plans, the environmental risks are acceptable.
3. Key points of environmental impact conclusion
The project is located in the company's existing factory area. The construction complies with the relevant national industrial policies and the "Chongqing City Industrial Project Environmental Access Regulations (Revision)" and other relevant regulations, and has good social, economic and environmental benefits.
The wastewater generated by the technological transformation project is discharged into the Yangtze River after being treated by the "iron-carbon micro-electrolysis + hydrolytic acidification, anaerobic" treatment process at the existing sewage treatment station. The technological transformation project has no new sewage outlets, and the whole plant wastewater after the technological transformation Its pollutant emissions have been reduced, which is conducive to the improvement of the surface water environment; the project process waste gas is discharged through the exhaust tube after being treated by the waste gas treatment facility; the project's clean production level is at the domestic advanced level. Therefore, from the perspective of environmental protection, the construction of the proposed project is feasible and the site selection is reasonable.
