摘　　要：采用电极生物膜法研究处理含硝酸盐氮的地下水。结果表明,温度过低或过高,对反硝化细菌的活性都有一定抑制;m(C)/m(N)为1时能实现总氮与总碳的同时去除,与理论计算的最经济m(C)/m(N)为1.07相近;电流的刺激作用可以提高异养反硝化菌的脱氮效率,其脱氮率和电流之间有大的关系,同时硝酸盐氮的负荷越大,电流要求越高;HRT越长,硝酸盐的去除率越高。The treatment of NO3^--N in Groundwater by a biofilm-electrode reactor demonstrated that whatever the temperature is excessive low or excessive high, the bacteria of denitrification will be controlled; when the m（C）/m（N）=1, and is lower than the theoretic value （1.07）. The current experiment confirmed that the current could improve the efficiency of the nitrate removal ratio, and the nitrate＇s eliminating ratio relates to the current, 1; The nitrate＇s eliminating ratio will be improved when the HRT is longer
