Qinghai Da Chaidan to achieve zero waste water discharge
发布时间：2024-06-21
- The wastewater produced in the production and operation of Dasaidan in Qinghai Province includes three kinds: underground dewatering water, domestic sewage and tailings wastewater. The drainage water in the mine is deposited by the sedimentation tank, and part of it is used for dust removal in the mining operation and the dump, and part of it is used in the processing plant. The domestic sewage is treated by A²O process and inclined plate precipitation process in the sewage treatment station, and is also used in the selection plant. After adding chemicals to remove the toxic and harmful substance sodium cyanide, the waste water from the concentrator is discharged into the tailings pond for clarification, and the supernatant is taken back to the concentrator. Therefore, in addition to evaporation consumption, 100% of the company's waste water is returned to the selection plant for recycling, achieving zero waste water discharge.
