Construction content and scale

Main environmental protection measures taken

structural work

1#、2#、3#production workshop

1 chloramphenicol intermediate production line with an annual output of 150t.

Collect the waste water from each step into a distillation kettle, firstly heat up the temperature to distill out the organic solvent, recycle it, and send the residual night to MVR to concentrate the salt. The distilled waste water is sent to the sewage treatment plant for treatment, and the salt is treated as hazardous waste; the production waste gas is reacted The self-contained exhaust pipe of the kettle enters the "first-stage bubble tower separation + second-stage paraffin oil spray absorption + third-stage lye spray absorption" and is discharged from a 15m high exhaust cylinder; waste residue is collected separately and temporarily stored in hazardous waste Temporary storage rooms are periodically handed over to hazardous waste disposal units for disposal; noise is discharged through equipment foundation shock absorption, wall sound insulation and distance attenuation to meet the standards; unorganized waste gas is delineated by sanitary protection distance to control its impact on the surrounding environment.

4# production workshop

1 aztreonan main ring (A98) production line with an annual production capacity of 30 tons; 1 K164 production line with an annual production capacity of 50 tons; 1 K13 production line with an annual output of 80 tons; 1 T97-C production line with an annual output of 100 tons. One.

5# production workshop

1 K199 production line with an annual output of 50t.

1 Cyclopropylamine production line with an annual output of 400t.

Environmental Engineering

Sewage treatment station

Designed processing capacity is 200m3/d, "physical and chemical + biochemical + post-processing" process, on the southeast side of the plant.

After dewatering, the sludge is temporarily stored in the hazardous waste temporary storage room and handed over to the hazardous waste disposal unit for disposal; set up a 150m3 wastewater accident emergency pool; set up green belts around the sewage treatment station to control its impact on the surrounding environment.

Accident pool

Temporary storage, after the sewage treatment facilities are in normal operation, the treatment reaches the standard discharge.

Circulating water station

The design capacity is 200t/h, and it is equipped with a 3000 m3 circulating pool (also used as a fire water station).

/

Hazardous waste is sent to a qualified unit for disposal

Regularly entrust Sichuan Zhongming Environmental Governance Co., Ltd. to collect and process
