Electroplating wastewater treatment methods

Electroplating wastewater treatment using at present: physical and chemical method, biological treatment method, ion exchange, electrolysis and so on. The above method is of high cost of treatment of electroplating wastewater, complex operation, a large number of low concentration of harmful pollutants difficult, etc. Laundry detergent production machine according to current situation of electroplating industry wastewater treatment in our country the statistics and investigation, there are 7 different classification methods widely used in the main: laundry detergent production machine, 1) Chemical precipitation, divide again for neutralization precipitation and sulfide precipitation. Laundry detergent production machine ( 2) REDOX process, divided into chemical reduction method, the ferrite method and electrolysis method. ( 3) Solvent extraction separation process. Reverse osmosis water treatment making machine ( 4) Adsorption method. Laundry detergent packing machine ( 5) Membrane separation technology. Liquid detergent production machine ( 6) The ion exchange method. Washing powder production machine ( 7) Biological treatment techniques, including biological flocculation method, biological adsorption method, chemical method, and the method of phytoremediation. But there are certain defects or serious irrationality. Detergent production factory house, the previous: the source and harm of electroplating wastewater
