摘要:
电镀企业产生的漂洗水中含有大量的重金属,处理后生成的电镀重金属污泥属于危废,国家有相关的处置规定,若处置不当,会对环境造成二次污染,并且造成重金属的流失。介绍了利用离子交换法、电解法、膜分离技术、电去离子法等相关方法回收电镀漂洗废水中重金属的国内外的研究进展;从源头抓起,减少了电镀企业重金属元素的排放量,同时对废水的合理回用提供一些可行性方案。

Abstract:
Rinsing water of electroplating factories contains plenty of heavy metal, and electroplating sludge will be generated after treatment of electroplating waste water. If the electroplating sludge was not properly treated and released to environment, it would cause heavily pollution to the soil and water system, and also would result in the loss of heavy metal. Introduced recycle heavy metal from electroplating rinsing water by methods of ion - exchanger, electrolytic, membrane separation, electrodenionization. The new progress of these methods was also introduced. It was suggested that we should reduce the amount of heavy metal from the first beginning of these process, and provide some feasible blue prints for the recycling work of electroplating waste water.
