| 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圹水,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.

| Abstract: | 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 A2O 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. |
