电镀废水的处理技术研究进展

Research progress on the treatment of electroplating wastewater

电镀废水含有大量的重金属离子,这些重金属离子具有很大的毒性,甚至有致癌的危险。因此,电镀废水的治理受到越来越多的研究者关注。主要介绍了化学沉淀法、离子交换法、吸附法、膜分离法及其它方法对电镀废水的处理,评价了各种方法的优缺点以及应用前景。

There are many heavy metals which have tremendous toxicity and cancerigenic hazardous in electroplating wastewater.So treatment of electroplating wastewater receives attention from more and more researchers.The chemical precipitation,ion exchange,adsorption,barrier separation and other method for treating electroplating wastewater,and estimates advantages and disadvantages and application foreground of various methods were introduced.
