摘要
随着工业的快速发展,工业废水处理的重要性日益凸显。电氧化技术具有氧化能力强,操作条件温和,不添加外氧化剂,无二次污染的特点,受到学者们的密切关注,在高毒性工业有机废水处理领域具有广阔的应用前景。介绍了近年来国内外电催化氧化处理的研究进展,首先介绍了三种阳极(钛基二氧化锡电极,钛基二氧化铅电极以及BDD电极)的制备方法、作用机理、目前存在的问题以及措施等。接着介绍了一种新型的电氧化方法——三维电极法,讨论了该方法常用的粒子电极类型及其相应电氧化效果。最后对电催化氧化方法当前的研究现状进行了总结,指出了未来的发展方向。
With the rapid development of the industry,the importance of industrial wastewater treatment has become increasingly prominent.Electrooxidation technology with the characteristics of strong oxidizing ability,mild operating conditions and no secondary pollution has been closely focused by scholars and has broad application prospects in the field of highly toxic industrial organic wastewater treatment.This paper introduces the research progress of electrocatalytic oxidation treatment at home and abroad in recent years.Firstly,the preparation methods,mechanism and current problems of three anodes(Ti/SnO2 electrode,Ti/PbO2 electrode and BDD electrode)were introduced.Then,a new type of electrooxidation mode——three-dimensional electrode was introduced.The types of particle electrodes used in 3-D electrode and their corresponding electrooxidation effects were discussed.Finally,the current research status of electrocatalytic oxidation method is summarized,and the future development is anticipated.
