摘　　要：考察了硝化菌添加A2/O系统的脱氮除磷效果及其特性。稳定运行时,系统对TCOD、SCOD、NH4+-N和PO43--P的平均去除率分别为77.58%、77%、95%和90.3%。实验结果表明,硝化菌添加对中试A2/O系统的硝化具有明显的强化效果,并且在短污泥龄和较小好氧池HRT条件下,生物添加A2/O系统实现了良好的硝化性能。The nitrogen and phosphorus removal effect and characteristics of A^2/O system with bio-augmentation were investigated. When A^2/O system operates steadily, the average removal rates of TCOD, SCOD, NH4^＋-N and PO4^3＋-P are 77.58%, 77%, 95% and 90.3%. The experiment result shows that, bio-angmentation for nitrification of AVO system had obvious strengthens effect. Under the low sludge age and little HRT of oxic plot, A^2/O system with bio-augmantation accomplished good performance of nitrification.
