摘要利用反硝化滤池耦合生物膜电极反应器（Denitrification filter coupled biofilm-electrode reactor，DF-BER）实现生物深度脱氮过程，考察了不同进水水质条件下，外加不同电流强度对DF-BER的脱氮性能、出水有机物种类和浓度的影响.结果表明，DF-BER通过降解实际污水中原有难降解有机物来强化系统反硝化效果，电流强度为5mA时，与以模拟污水为进水相比，系统脱氮率提高14.7%.随着外加电流强度的增大，DF-BER的脱氮效果增强，实际污水出水中色氨酸类芳香族蛋白质含量降低，实际污水和模拟污水出水中均出现微生物代谢产物和腐殖酸积累现象.

Abstract：The denitrification filter coupled biofilm-electrode reactor (DF-BER) was employed to realize the biological deep nitrogen removal process. The effects of different currents on the nitrogen removal performance of DF-BER and the types and concentration of effluent organic matter were systematically investigated under conditions of different influent water quality. The results indicated that DF-BER strengthened the denitrification effect of the system via degrading the original refractory organic matter in the actual sewage. When the current was 5mA, the system denitrification rate increased by 14.7% compared with that of the simulated sewage as the influent. With the increase of the applied current, the nitrogen removal performance of DF-BER was significantly enhanced, and the content of the tryptophan aromatic protein in actual sewage effluent was greatly reduced. In the meantime, microbial metabolites and humic acid accumulation appeared in effluent from both actual sewage and simulated sewage.

Key words： denitrification filter coupled biofilm-electrode reactor three-dimensional electrode current intensity autotrophic denitrification actual sewage
