Abstract:
This paper introduces the treatment technology, process, structure parameters and operation performance of a 7 000 m3/d centralized electroplating wastewater treatment project. This project is in a electroplating industrial park, which is a national standard environmental protection industrial park. Through the integration of physicochemical collateral-breaking technology and biochemical A/SCBR technology, the effluent stability can be achieved under the great fluctuation of influent pollutant concentration. Among them, heavy metals and cyanide indicators meet requirements of Table 3 of Pollutant Discharge Standards for Electroplating(GB 21900-2008). The process technology system run steadily, have good treatment effect and high automation degree, which achieve great environmental, social and economic benefits.
