摘　　要：采用电极生物膜法处理含硝酸盐氮的废水,结果表明:在碳氮质量比较低(m(C)/m(N)为1)的条件下,电极生物膜法比单纯生物膜法有更高的反硝化效率;无外加有机物(m(C)/m(N)为0)时,间歇式反应器比连续式反应器有更好的脱氮效果,更能有效地控制亚硝酸盐氮浓度。Biofilm-electrode process was used in treatment of wastewater containing nitrate nitrogen. The result shows that： biofilm-electrode process has higher efficiency of denitrification than single biofilm at low C/N ratio（m（C）/m（N） = 1 ）; with no organics addition （m（C）/m（N） = 0）, intermittent biofilm-electrode reactor has better effect of denitrifieation and better efficiency for controlling of concentration of nitrite nitrogen than continuous biofilm-electrode reactor.
