摘　　要：电渗法能量利用率低一直是制约其应用的主要问题之一。为了提高电能利用率、减小电极腐蚀,促进电渗法在实际工程中的应用,对造成电渗法能量消耗巨大的原因进行了探讨;基于电解水反应、界面电阻、土体含水量等指标,对反转电极、间歇通电、改变电极材料三种方法进行了比较,并提出优化方案。同时基于电化学理论阐述了三种方法提高电能利用率的原因,并为下一步的研究和改进给出建议。The low energy utilization of the electro-osmosis most is one of the major issues that limiting its practical applications.In order to improve the energy utilization rate,reduce the electrode corrosion and promote the application of the electroosmotic method in the practical engineering,this paper mainly discussed the causes of the huge energy consumption of the electroosmotic method.Based on the indexes of electrolyzed water reaction,interface resistance and soil water content,three methods of reversing electrode,intermittent energization and changing electrode materials were compared and the optimization scheme was put forward.At the same time,this paper explained the reasons why these three methods can improve the energy utilization rate based on the electrochemical theory.
