A modified anaerobic-anoxic-oxic (AAO) reactor embedding electrolysis was constructed for treatment of low carbon/nitrogen (C/N) wastewater. The effect of different current conditions on the performance of reactor was investigated in this study. When the current ranged from 0 mA to 200 mA, the removal efficiency of total nitrogen (TN) increased from 61.25% (0 mA) to 75.60% (200 mA), and that of total phosphorus (TP) increased from 72.24% (0 mA) to 93.93% (200 mA). In addition, the removal efficiencies of chemical oxygen demand (COD) and NH-N were not affected. The results indicated that AAO reactor coupling electrolysis was an effective way to strengthen the removal of nitrogen and phosphorus for treatment of low C/N wastewater.
构建了一种改良的厌氧-缺氧-好氧（AAO）反应器并嵌入电解工艺，用于处理低碳氮比（C/N）废水。本研究考察了不同电流条件对反应器性能的影响。当电流从 0 mA 增加到 200 mA 时，总氮（TN）的去除效率从 61.25%（0 mA）提高到 75.60%（200 mA），总磷（TP）的去除效率从 72.24%（0 mA）提高到 93.93%（200 mA）。此外，COD 和 NH-N 的去除效率不受影响。结果表明，AAO 反应器耦合电解是强化低碳氮比废水脱氮除磷的有效方法。
