摘要

电絮凝技术是一种以电化学为基础的净水方法，其吸附能力远高于一般的絮凝剂，具有设备简单、操作方便、无污染、产生的污泥量较低、不需要添加任何阴离子的特点，在水处理中的应用越来越多。介绍了电絮凝的基本原理，列出了影响电絮凝的主要因素（pH值、电流密度、电解时间、极板间距），并综述了其在水处理中的研究现状，提出了目前电絮凝法存在的问题，并对其在水处理工艺方面的发展趋势和应用前景进行了展望。

Abstract：

Electroflocculation technology is an electrochemical-based water purification method, which adsorption capacity is much higher than that of ordinary flocculants, and it has the characteristics of simple equipment, convenient operation, no pollution, low amount of sludge, no need for adding any anions, and more and more applications in water treatment. The basic principle of the electric flocculation was introduced, the main factors affecting electroflocculation (pH value, current density, electrolysis time, plate spacing) were listed, the research status in water treatment was reviewed, the current existing problems of the electroflocculation methods were put forward, and its development trend and application prospect in water treatment process were prospected.

Key words： electrocoagulation influencing factor water treatment
