The biological nitrogen and phosphorus removal was investigated in two anaerobic-anoxic-aerobic sequencing batch reactors (SBRs), which were fed with synthetic and municipal wastewater, respectively. The operating cycle of (AO)3 SBR was 1.5 h anaerobic --> 1 h aerobic --> 1 h anoxic -->20 min aerobic --> l h anoxic --> 20 min aerobic. The removal efficiency of COD, total nitrogen and total phosphorus for synthetic wastewater was 88%, 89%, 99%, respectively, while it was 85%, 75% , 99.5% for municipal wastewater. Furthermore, it was observed that though there were much differences in polyhydroxyalkanoates (PHAs) accumulation and phosphorous release in the anaerobic stage between two SBRs, the ratio of the anoxic energy production efficiency to the aerobic one was close to each other (49% versus 50%).
在两个厌氧-缺氧-好氧序批式反应器（SBR）中研究了生物脱氮除磷效果，这两个反应器分别采用合成废水和城市污水作为进水。(AO)3 SBR的运行周期为1.5小时厌氧→1小时好氧→1小时缺氧→20分钟好氧→1小时缺氧→20分钟好氧。合成废水的COD、总氮和总磷去除效率分别为88%、89%、99%，而城市污水的去除效率分别为85%、75%、99.5%。此外，观察到尽管两个SBR在厌氧阶段的聚羟基脂肪酸酯（PHA）积累和磷释放存在很大差异，但缺氧阶段与好氧阶段的能量产生效率之比彼此接近（49%对50%）。
