摘　　要：为克服传统曝气生物滤池工艺生物除磷效果差的缺点,开发了厌氧好氧交替BAF生物除磷工艺。在厌氧好氧交替曝气时间为12h,水力停留时间为1.4～2.9h的条件下,考察了该工艺处理生活污水的效果。结果表明,该工艺对COD和总磷的平均去除率分别可达91.89%和77.89%,总磷的去除率最高可达87.92%;对总氮和氨氮的平均去除率不理想,分别只有34.7%和41.6%。该工艺表现出良好的去除COD和除磷性能。In order to overcome the shortcoming of the traditional biological filter on biological phosphorus removal capacity, the biological phosphorus removal crafts of the alternate anaerobic/aerobic biological aerated filter was developed recently. When the altemate aeration of aerobic/anaerobic is 12h and hydraulic retention time（HRT）is 1.4-2.9 h, the effect of this craft processing domestic wasterwater was investigated. The results shown that COD, TP average removal efficiency are up to 91.89%, 77.89%, total phosphorus removal can reach up 87.92%; but TN and NH4^- -N average removal efficiency are only 34.71% and 41.57% respectively. This craft displays good performance about COD and TP removal.
