摘　　要：鞍山市某电镀废水回用处理工程设计规模为14.6 t/d,在综合分析电镀生产各工段水质及处理电镀废水常用工艺方法后,确定采用“电絮凝+反渗透膜”处理工艺路线.详细介绍了其工艺流程、运行参数、运行效果及处理成本等。通过该工艺处理后,产水水质高于《电镀污染物排放标准》(GB 21900-2008),处理成本节约了100~150万元/a,节水约5000 t/a,具有良好的经济效益和环境效益.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 5000 t/a,and has good economic and environmental benefits.
