电絮凝技术在水处理中的研究进展综述

摘要

Electrocoagulation (EC)is an eco-friendly water treatment technique which is becoming a research focus due to its advantages. Firstly,the basic theory related to electrocoagulation was introduced from the electrode reaction principle,water purification mechanism and technical characteristic;secondly,detailed application status of electrocoagulation technology were discussed in the light of wastewater treatment,sewage treatment,water treatment and micro-polluted seawater treatment;Finally,a conceptual framework was presented for future research directed towards improving power source and electrode configuration,optimizing cell form and combined process on the basis of minimizing electrical power consumption and reducing electrode passivation.%作为一种环境友好型技术，电絮凝凭借诸多优点逐渐成为研究热点。该文从电极反应原理、净水机理、技术特征三个方面，介绍了与电絮凝相关的基本理论。再从废水处理、污水处理、给水处理及微污染海水处理四个方面详细论述了电絮凝技术的应用现状。最后针对电絮凝能耗较高和电极易钝化的问题，提出改进电源和电极、优化电解槽形式及与其他工艺相组合的发展方向。
