Design and application of"electrolytic+reverse osmosis membrane"in electroplating wastewater project
The reuse project of an electroplating wastewater in Anshan city,the treatment design scale is 14.6 t/d.After the comprehensive analysis of the water quality and the common process of electroplating wastewater,the treatment process route of"electric flocculation+reverse osmosis membrane"was determined.The process flow,operation parameters,operation effect and processing cost were introduced in detail in this paper.The treated water is higher than the electroplating pollutant discharge standard(GB 21900-2008).The treatment cost saves 1～1.5 million yuan/a,saving water about 5 000 t/a,and has good economic and environmental benefits.
