2.1.4 Industrial Engineering

2.1.4.1 Water supply and drainage

Production water and domestic water come from the urban water pipe network (100 tons / hour);

A circulating cooling pool is set up in the factory area to implement a closed circuit cycle. The cooling tower works continuously during the process;

Production wastewater and domestic sewage are discharged into Xinchengzi Urban Sewage Treatment Plant after being treated by the sewage treatment station in the plant area;

2.1.4.2 Power supply

The district agricultural power bureau has dual-circuit power supply, which consists of 500KVA and 630KVA transformers each with two box transformers.

2.1.4.3 Heating and steam supply

The boilers are each 10t / h and 6t / h steam boilers, one for each use and one for backup.

(1) 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. The sewage is discharged after reaching the standard after being treated by the environmental protection biochemical system. Adopting anaerobic and aerobic processes, with a processing capacity of 40 tons / day, after treatment, it will be discharged into the municipal pipe network and then entered into Xinchengzi sewage treatment plant
