摘　　要：电絮凝是一种环境友好型技术。电絮凝方法占地面积小,不需要添加化学试剂,污泥量少,操作简单,可以有效去除水中的COD、重金属、色度、氟化物和有毒有害物质。本文介绍了电絮凝处理水的基本原理,综述了电絮凝在水处理中的应用及存在的不足,提供了解决方法。针对能耗较高的问题,可从改进电源、研制新电极和与其他技术连用等方面研究。Electrocoagulation（EC） was a kind of environment-friendly technology. EC process with the advantages of less space, no addition of chemicals, less sludgen and operate easily, was widely applied in water and wastewater treatment to remove COD, heavy metals, color, fluoride and substances of toxic or harmful. The fundamental principle of electrocoagulation, the application and weakness of eIectrocoagulation, and some solutions were reviewed. Some measures can be taken to settle the anode＇ s passivation, including improvement of power technique, development of new type electrode, combination with other techniques and so on.
