(2) Wastewater: Wastewater produced in the production process mainly includes washing water for drawing area, water for drawing spray, water for cleaning waste wire, hard water and domestic sewage produced by soft water preparation. The hard water produced by the soft water preparation is directly discharged as clean sewage, the rest of the production and domestic wastewater is treated at the sewage treatment station of the factory, the sewage that reaches the standard is reused into the production system, and the surplus part is connected with the sewage pipe network of the park. In the first phase of the project, the design scale of the wastewater treatment station is 2400m3/d, and the output of the wastewater is about 900m3/d. The wastewater is reused from 500 m3/d to the drawing area as the washing water, and is discharged from 300 m3/d to the sewer network of the park.
