含Cr(Ⅵ)废水的电化学法处理技术研究进展

Research Progress of Electrochemical Treatment Technology for Wastewater Containing Cr(Ⅵ)

在制造业中,Cr(Ⅵ)通常随废水一起排放,给环境造成了严重污染。为了从废水中去除Cr(Ⅵ),研究人员已经开发了多种不同的处理技术。其中,电化学技术因其清洁、高效、低成本等优势而表现出巨大的潜力和应用前景,能满足日益严格的环境法规要求。本文介绍了近年来应用电絮凝、电还原、电渗析等电化学技术净化含Cr(Ⅵ)废水的研究进展,并对其未来发展进行了展望。

In the manufacturing industry,Cr(Ⅵ) is usually discharged together with wastewater,causing serious pollution to the environment.In order to remove Cr(Ⅵ) from wastewater,researchers have developed a number of different treatment techniques.Among them,electrochemical technology shows great potential and application prospects due to its advantages of cleanliness,high efficiency,and low cost,which can meet increasingly stringent environmental regulations.This paper introduces the research progress made in recent years in the application of electro-flocculation,electro-reduction,electro-dialysis and other electrochemical technologies to purify Cr(Ⅵ)-containing wastewater,and prospects for its future development.
