摘　　要：电凝聚法是一种对环境二次污染很小的废水处理技术,具有广阔的应用前景。但是,因其电化学过程中可溶性铝或铁阳极的钝化现象而限制了其高效低能耗应用。从电凝聚电极过程的分析入手,讨论了电极钝化的本质原因及消除电极钝化的措施,并介绍了笔者采用自行研制的交变脉冲电凝聚专用电源,彻底消除电极钝化方面的研究进展。＂Electric agglomerate method＂ is a technology of wastewater treatment with little secondary pollution and a wide application prospect. However, Its high efficiency and low energy cost application is limited as the dissoluble aluminium exits and the iron anode is passivated in the course of electrochemistry .This paper analyzes the process of electric agglomerate, discusses the essential reason why electrode is passivated and provides the measures how to avoid electrode being passivated.At the same time, the author indicates the research development of how to use the altemating current pulse electrical source （home - made special for electric agglomerate）to avoid electrode being passivated completely.
