Treatment Indicators
●Wastewater sources
The discharged wastewater consists of three parts: wastewater produced by chromium production line, wastewater discharged by the power plant, and domestic sewage of the whole plant.
●Major pollutants
The major pollutants in chromium-containing wastewater include hexavalent chromium, as well as COD, BOD5, SS, sulfide, ammonia nitrogen, etc.
●Treatment scale
1000m3/d, the daily run time is 24h, and the average design treatment capacity is 42m3/h.
●Effluent water standards
Implement the “Code for Design of Wastewater Reclamation and Reuse” (GB50335-2002). The reclaimed water is used as make-up water for the circulating cooling system.
