Electroplating Wastewater | Electroplating Wastewater Classification - Electroplating Wastewater Treatment Process

　　Regarding electroplating wastewater, the following mainly discusses the basic concepts of electroplating wastewater, the classification of electroplating wastewater and the electroplating wastewater treatment process.

　　I. Electroplating Wastewater

　　Electroplating wastewater

　　Refers to various wastewaters discharged during the electroplating production process, including pickling wastewater, rinsing wastewater, passivation wastewater, wastewater from scrubbing floors and plates, wastewater generated by "running, bubbling, dripping, and leaking" due to poor operation or management, water used in the wastewater treatment process, and laboratory drainage.

　　II. Classification of Electroplating Wastewater

　　Electroplating wastewater is generally classified according to the type of pollutants or heavy metal ions contained in the wastewater, such as acid-base wastewater, cyanide-containing wastewater, chromium-containing wastewater, heavy metal-containing wastewater, etc. When the wastewater contains more than one pollutant (such as cyanide cadmium plating, which contains both cyanide and cadmium), it is generally still classified according to one of the pollutants; when the same plating type has several process methods, it can also be divided into subcategories according to different processes, such as pyrophosphate copper plating wastewater, copper sulfate copper plating wastewater, etc. Wastewater that mixes different plating types and different pollutants is collectively referred to as electroplating mixed wastewater.

　　III. Electroplating 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.
