Electroplating Mixed Wastewater | How to Treat Electroplating Mixed Wastewater (Process)

　　I. What is electroplating mixed wastewater?

　　It refers to wastewater discharged from electroplating production that is a mixture of different plating types and different pollutants. Including pre-treated cyanide-containing wastewater and chromium-containing wastewater.

　　II. How to treat electroplating mixed wastewater

　　Characteristic pollutants in electroplating mixed wastewater, such as metal ions and cyanide such as chromium, cadmium, lead, nickel, silver, copper, zinc, iron, aluminum, etc., should be treated at the workshop drain outlet; pollutants such as COD, BOD, total phosphorus, total nitrogen, ammonia nitrogen, chromaticity, petroleum, suspended solids, fluoride, etc. should be treated at the total discharge outlet.

　　III. Electroplating mixed wastewater treatment process

　　With own core patented technology of "zero discharge" for metal industrial wastewater, through the technical route of "wastewater diversion, classification treatment, wastewater reuse, and resource recovery", by adopting the combined process of "heavy metal high-precision removal pretreatment + OSMMBR biochemical technology + SPNR technology + MVR crystallization technology" of Shangchen Environment, all the treated heavy metal wastewater are used for production, the wastewater reuse rate is increased to 99.6%, which maximized the recycling of water resources. Furthermore, it can significantly reduce treatment costs, reduce the amount of solid waste generated, and transform metal ions in wastewater into resources, completely achieving zero discharge of wastewater.
