摘　　要：为解决电化学水处理技术中提高电催化效率和延长电极寿命的问题,在综合以上两方面国内外的研究成果及解决途径的基础上,指出DSA电极因其高的稳定性,且可通过设计制备-定结构的表面涂层而获得具有不同结构的阳极材料;DSA电极用于有机物氧化降解存在直接和间接电化学氧化两种过程,而涂层表面结构中氧空位浓度与电极性质密切相关.The characteristics, principle and application of electrochemical technology and the current efficiency and the service life of the electrodes are reviewed. A kind of electrodes with high catalytic efficiency, dimensionally stable anodes (DSA) and its application in organic wastewater treatment are discussed with pathway of degradation suggested for some organics, such as aromatic compounds, and the preparation of DSA anodes was discussed as well.
