摘　　要：采用UniFed SBR工艺实验装置处理实际生活污水,分析了进水C/P质量比对UniFed SBR工艺性能的影响。结果表明,控制充水比为33%、进水C/N比在6左右,当C/P比≥33时,可以实现磷的100%去除,出水中检测不到PO34-浓度;当C/P比<33时,磷的去除率随C/P比的增加而线性提高。进水C/P比的变化,对总氮和COD的去除影响较小,平均去除率分别为84%和94.5%。UniFed SBR process is used to treat wastewater in this study, and the effects of influent C/P ratio on its performance is investigated. The results show that when the volume exchange ratio and influent C/N ratio are fixed to 33 % and 6 respectively,and C/P ratio is higher than 33,the phosphorous removal efficiency can maintain 100% and PO4^3- cannot be detected in the effluent. When C/P ratio is lower than 33, the phosphorous removal efficiency increases as C/P ratio increases linearly. However, TN and COD removal are hardly affected by feed C/P ratio. The average removal efficiencies of TN and COD can be 84 % and 94.5 %, respectively.
