摘　　要：电絮凝技术广泛应用于污废水处理当中,耗时短、占地小、处理效率高的特点,让其应用前景广阔。但是电絮凝过程中电极表面容易产生钝化膜,从而阻碍电絮凝反应,增加能源消耗,降低其应用效率。本文综述了电絮凝反应过程中影响电极钝化的主要因素以及消除电极钝化方法的研究进展,最后进行了简要的总结与展望。Electrocoagulation was widely used in the treatment of wastewater.The characteristics of short time consumption,small footprint,and high processing efficiency made its application prospects broad.However,the electrode surface was prone to passivation during the electro-coagulation process,which hindered the flocculation reaction,increased energy consumption,and reduced the efficiency of its application.The article reviewed the main factors affecting electrode passivation during the electrocoagulation reaction and the progress of research on methods to eliminate electrode passivation.Finally,a brief summary and expectation were discussed.
