Abstract: 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.
