摘　　要：碳量偏低对城市污水进行脱氮除磷来说比较困难。研究采用化学磷回收辅助A2O工艺处理低碳城市污水,考察生物除磷效果及其影响因素。试验结果表明:磷的出水浓度可以达到0.5 mg/L以下,且可以实现磷的回收;HRT、SRT和DO是影响除磷效果的关键因素。Low-carbon content is always a difficult problem for nitrogen and phosphorus removal from urban wastewater. In this paper, the test was made on low-carbon urban wastewater treatment by using A2 O process （combined with chemical phosphorus recovery） to investigate the effect and affecting factors of biological phosphorus removal. The result showed that phosphorus concentration in effluent was below 0. 5 mg/L and the P in influent could be recovered; the key factors affecting phosphorus removal were HRT, SRT and DO.
