The metal processing production wastewater is mainly heat treatment and cleaning of metal products, containing a certain amount of oil, surfactant, metal residue, etc., which is characterized by high content of organic matter and suspended solids. Metal surface treatment wastewater is mostly pickling wastewater, mechanical processing wastewater, electroplating wastewater and circuit board wastewater. The production process is complex, the types of wastewater are numerous, the water quality and quantity are variable, and the treatment cost is high. In this kind of wastewater treatment, the net source membrane technology classifies the wastewater quality according to the production process of different owners, and specifically designs the wastewater treatment process with the ultrafiltration membrane technology as the core, which not only ensures the wastewater treatment effect of the owner, but also It saves corporate investment and production operating costs.
