摘要

电极生物膜法反硝化是一种新型的将电化学法与生物膜法相结合的生物反硝化方法.特别在缺乏碳源时,该法为反硝化提供了一种新的途径.结合国内外对电极生物膜法反硝化的研究发展,系统介绍了电极生物膜法反硝化工艺的影响因素,同时指出该工艺在电极材料的选择、反应器构型设计、电化学和生物膜协同作用的原理与条件优化方面存在的问题和今后的研究发展趋势.%Biofilm-electrode denitrification is a novel method which combines electrochemical method with biofilm process. It provides a new approach,especially when there is lack of carbon source for denitrification. According to the development of research on denitrification by biofilm-electrode reactor in China and aboard,the factors influencing denitrification by biofilm-electrode reactor are introduced systematically. At the same time,the problems existed in the aspects, such as the selection of electrode materials in this process, the design of reactor configuration, and the principle and condition optimization of the synergistic effect between electrochemistry and bio-film,as well as the trend of future research development, are put forward.
