摘　　要：采用电极生物膜法处理含亚硝酸盐的废水.研究结果表明,电极生物膜法比单纯生物膜法反硝化效率高出40%;间歇式反应器比连续式反应器反硝化效率高出20%-30%;在m（C）/m（N）=1.5,I=40 mA,HRT=12 h的条件下,亚硝酸盐氮去除率最高可以达93%.Biofilm-electrode process is used in treatment of wastewater containing nitrite nitrogen.The research shows that the efficiency of biofilm-electrode process is 40% higher than that of the biofilm process without electrode;the efficiency of intermittent biofilm-electrode reactor is 20%-30% higher than that of continuous biofilm-electrode reactor;C/N ratio is 1.5,I of 40 mA,HRT of 12 h,the NO2^- —N removal efficiency is over 93%.
