Coating Wastewater Treatment

Automobile manufacturing coating will emerge many kinds of wastewater, complicated composition, huge water quality difference and water imbalance. For example, electrophoresis wastewater, liquid viscous paste, appearance, black epoxy resin, carbon black, solvents and powder, electrophoresis and slag, those all are prone to be agglomerated. But the paint contains large amount of water soluble organic solvent. The COD removal is less than 30% if it is only coagulation.
According to our practical experience for many years, the use of reasonable QingZhuo points, the first batch after pretreatment were concentrated continuous coagulation precipitate and chemical treatment air-flotation treatment, not only has good and stable effect, but also feasible in economy.
