Annex III to the environmental emergency plan

The main sources of pollution danger during the process are as follows:
　
The company's main environmental hazard chemicals are biphenyl, hydrochloric acid, paraformaldehyde, cyclohexane, zinc chloride, triethyl phosphite, sodium methoxide, sodium o-sulfonate benzaldehyde, dimethyl sulfoxide, and methanol If a leak occurs, there is a danger of causing fire, explosion, and environmental pollution. Zh

The company has one comprehensive warehouse, two raw material warehouses, and one dedicated warehouse. It is a steel frame structure or brick-concrete structure, which is used to store production raw materials and packaging materials. The company's factory area is equipped with a 400m3 accident emergency pool. There are also one hazardous waste storage place and one general solid waste storage place. See Table 1-3 and Table 1-4 for chemical storage conditions in the plant area.

1.3 Industrial Engineering
　
1.3.1 Water supply and drainage
　
Production water and domestic water come from the urban water pipe network (100 tons / hour);
　
The circulating water comes from two self-provided wells (80 tons / hour in total). A circulating cooling pool is set up in the plant area to implement closed-loop circulation. The cooling tower works continuously during the process;
　
Production wastewater and domestic sewage are discharged into the urban sewage treatment plant in Shenbei New District after being treated by the sewage treatment station in the plant area;
　
Rainwater is collected into a pipeline and discharged into the municipal rainwater pipe network.
　
13.2 Power
　
The district agricultural power bureau has dual-circuit power supply, which consists of 500KVA and 630KVA transformers each with two box transformers.
　
1.3.3 Heating and steam supply
　
The boilers are each 10t / h and 6t / h steam boilers, one for each use and one for backup.
　
1.3.4 Production of Three Wastes and Disposal
　
(1) Wastewater
　
The company's wastewater mainly comes from the domestic sewage of employees and a small amount of process wastewater, and the water used for washing the ground, with an annual discharge of about 36,000 tons. Sewage meets the standards and is discharged after being treated by two environmental protection biochemical systems. The western plant area adopts anaerobic and aerobic processes, with a processing capacity of 40 tons / day. After treatment, it is discharged into the municipal pipe network and entered the sewage treatment plant in the Shenbei New Area;
