摘要:: 多阴极室反硝化除磷产电装置中，将微生物燃料电池引入双污泥反硝化除磷工艺，以厌氧池作为微生物燃料电池的阳极室，以好氧池、二沉池、缺氧池和终沉池分别作为微生物燃料电池的阴极室。以模拟生活污水为处理对象，多阴极室反硝化除磷产电装置经过调控以后进入稳定运行状态，在60 d的测定周期中，对COD、NH₄⁺-N和PO₄^3--P的平均去除率分别为69.88%、62.31%和57.13%，最高去除率分别为80.44%、74.16%和64.86%，厌氧和好氧池、厌氧和二沉池、厌氧和缺氧池、厌氧和终沉池作为4组微生物燃料电池产生的电压和电流平均值分别为0.44、0.40、0.09、0.10 V和0.49、0.45、0.10、0.11 mA，最高电压分别达到了0.55、0.51、0.13、0.12 V。多阴极室反硝化除磷产电装置不仅增强了对生活污水中COD、NH₄⁺-N和PO₄^3--P的去除效果,而且提高了产电性能。

Abstract:: In a multicathode denitrifying phosphorus removal and electrogenesis device treating simulated domestic sewage, principle of microbial fuel cell was introduced into the double sludge denitrifying phosphorus removal process, the anaerobic tank was served as anode of the microbial fuel cell, and the aerobic tank, secondary sedimentation tank, anoxic tank and final sedimentation tank were used as the cathode of the microbial fuel cell. After 60 days of debugging and operation of the multi-cathode chamber denitrifying phosphorus removal and electrogenesis device, average removal rates of COD, NH⁺₄-N and PO^3-₄-P were 69.88%, 62.31% and 57.13%, respectively, and the maximum removal rates were 80.44%, 74.16% and 64.86%, respectively. The average voltages and currents generated by four groups of microbial fuel cells (anaerobic and aerobic tanks, anaerobic and secondary sedimentation tanks, anaerobic and anoxic tanks, anaerobic and final sedimentation tanks) were 0.44 V, 0.40 V, 0.09 V, 0.10 V and 0.49 mA, 0.45 mA, 0.10 mA, 0.11 mA, respectively, and the highest voltages were 0.55 V, 0.51 V, 0.13 V, 0.12 V, respectively. The multicathode chamber denitrifying phosphorus removal and electrogenesis device not only improved the removal efficiencies of COD, NH⁺₄-N and PO^3-₄-P of domestic sewage, but also enhanced the electricity production performance.
