Linhai Jianxin Chemical Co., Ltd Technical transformation projects of 300 t / a trimethyl sulfoxide, 50 t / a methyl triphenylphosphonium bromide, 2400 T / a methyl bromide and other products

Environmental impact assessment information publicity

1、 Basic information of construction project

Linhai Jianxin Chemical Co., Ltd. is located in Linhai Park, chemical API base of Zhejiang Province. It is planned to invest 7.5 million yuan to implement the technical transformation project of 300 tons of trimethyl sulfoxide, 50 tons of methyl triphenylphosphonium bromide and 2400 tons of methyl bromide in the existing plant area. After the implementation of the technical transformation project, the annual production capacity of 300 tons of trimethyl sulfoxide, 150 tons of dimethyl sulfone, 50 tons of methyl triphenylphosphonium bromide, 2400 tons of bromomethane and 1500 tons of calcium sulfate will be formed, and the product chain of the enterprise's bromomethane will be developed.

2、 Distribution of main environmental sensitive targets within the scope of environmental impact assessment

The main environmental sensitive targets within the scope of environmental impact assessment are Shuangzha Village (about 1410m to the West outside the plant boundary), duxiapu village, Baojia village, Changheng village, tuanheng village, hekanxia village, shuqiaotou village, caotan village and other environmental sensitive targets.

3、 Main environmental impact prediction

Construction period: the main pollutants are construction dust, construction noise, domestic sewage and solid waste generated during the construction period. Reasonable prevention and control measures are taken to make each pollutant discharge up to the standard, with little impact on the surrounding environment.

Operation period: after the wastewater is pretreated by different quality, it will be brought into the wastewater treatment facilities in the plant for treatment, and then it will be piped into the wastewater treatment plant for treatment, and then it will be discharged without obvious impact on the surrounding environment; the waste gas will be collected and pretreated by different quality, and then it will be treated by the waste gas treatment facilities at the end of the plant for treatment, and then it will be discharged at high altitude, without obvious impact on the surrounding environment; the solid waste is mainly high boiling matter Waste molecular sieve, waste packaging materials, waste water station sludge and domestic garbage, etc. are treated by recycling and harmless treatment to reduce the impact on the environment; the noise is mainly from the operation of mechanical equipment, etc. the noise at the plant boundary is up to the standard by taking sound insulation, greening and other measures. Take reasonable prevention and control measures to make all pollutants reach the discharge standard, and the project has little impact on the surrounding environment.

4、 Main environmental protection measures to be taken, environmental risk prevention measures and expected effects

Construction period: new office buildings, class C warehouses, etc. will be built in the existing plant area of this project. The construction site will be watered regularly to reduce outdoor stacking and dust suppression. It is strictly prohibited to work at night and take relevant noise reduction measures. Civilized construction and collection of domestic sewage and solid waste will not have a significant impact on the surrounding environment.

Operation period: the process waste water will be treated in the built-in waste water treatment facilities of the plant after being pretreated in different quality, and then it will be piped into the waste water treatment plant for treatment and then discharged; the process waste gas and waste gas from solid waste yard will be treated in the end treatment facilities (alkali water secondary spray + UV photodegradation + activated carbon adsorption) for treatment and then discharged; the waste gas from the waste water station will be collected and then used (acid alkali secondary spray + light) Deodorization) treatment; selection of low-noise equipment, sound insulation and noise reduction of high-noise equipment to reduce the impact of noise; classified collection and separate disposal of solid waste in strict accordance with relevant specifications; seepage prevention work of underground water in strict accordance with the requirements, tracking and monitoring work; establishment of emergency system and emergency pool. The prevention and control measures adopted in the project are technically and economically feasible, which can ensure the stable discharge of various pollutants up to the standard, and the discharged pollutants will not have a significant impact on the surrounding environment.

5、 Preliminary conclusion of environmental impact assessment

The impact of various pollutants generated by the project on the surrounding environment is within the acceptable range and the environmental risk is within the acceptable level. The project basically conforms to the principle of environmental protection approval.

6、 Content for comments

Scope and main items of consultation: relevant groups and individuals within the scope of EIA of the project can put forward opinions and suggestions on the environmental protection countermeasures of the project or other issues related to the environmental impact of the construction project, and explain the reasons.
