摘要:

电化学杀菌是一种对环境友好的杀菌技术,现对该技术近30 a在杀菌机理和电极材料方面的研究进展进行了总结。电化学杀菌的机理包括活性氯、H2O2、O3、活性中间体、铜或银离子的化学作用以及电场的物理作用;采用的电极材料分别为钛阳极、炭阴极、PbO2阳极等;根据应用对象和目标选择适宜的电极材料,是提高杀菌效果的有效途径;目前电化学杀菌技术存在的主要问题是电流效率较低,阴极结垢以及杀菌剂浓度难以控制等。

Abstract:

Electrochemical disinfection is a new disinfection process friendly to environment. The development of disinfection mechanisms and electrode materials in the last thirty years is reviewed. Electrochemical disinfection mechanisms include the chemical effects of active chlorine, hydrogen peroxide, ozone, active intermediates, copper or silver ions and the physical effect of electric field, respectively adopting titanium anodes, carbon cathodes, and PbO2 anodes etc. It is concluded that the selection of a proper electrode material according to targets and objects is an effective approach to improve disinfection efficiency. The main problems of present electrochemical disinfection are comparatively low current efficiency, the formation of scales on the cathode surface and the difficulty to control the disinfectant concentration etc.

Key words: disinfection, electrochemical, water treatment
