摘要
电化学处理技术通过一系列电极反应去除难降解废水中的污染物,它拥有独特的优势和众多的优点,已成为处理难降解废水的重要方法﹒文章通过介绍微电解法、电芬顿法和三维电解法等常用电化学处理技术的原理和进展,分析总结出这些电化学处理技术普遍存在的极板钝化和填料钝化等问题﹒因此,将其与物理法、生物法和化学法联合使用,可以改善单独采用电化学法存在的不足;未来电化学处理技术的研究主要集中在寻找能够降低能耗的新型电极板、选择绿色经济的发电方式、制备低成本的电极粒子和开发与其他工艺的联合使用等方面.
Electrochemical treatment technology removes pollutants in refractory wastewater through a series of electrode reactions.It has become an important method to treat refractory wastewater for its unique and numerous advantages.The principle and progress of common electrochemical treatment technologies such as micro electrolysis,electro-Fenton method,and three-dimensional electrolysis are introduced.The common problems of plate passivation and filler passivation in these electrochemical treatment techniques are analyzed and summarized.Therefore,the deficiency of using electrochemical method alone can be improved by combining it with physical method,biological method and chemical method.It is believed that future research on electrochemical processing technology will mainly focus on finding new electrode plates that can reduce energy consumption,choosing green and economical power generation methods,preparing low-cost electrode particles and developing joint use with other processes.
