摘　　要：　碳、氮、磷比例失调(碳量偏低)城市污水的脱氮除磷一直是个难题,为此采用SBR法处理广州地区低碳城市污水,研究了生物除磷效果及其影响因素。结果表明,磷的出水浓度<0.5mg/L,并指出污泥龄及DO是影响除磷效果的关键因素。The disproportion of C,N and P (low carbon content) are always a puzzle for nitrogen and phosphorus removal from urban wastewater.Based on this,test was made on low carbon source urban wastewater treatment in Guangzhou region by using SBR process to investigate the effect and affecting factors of biological phosphorus removal.The result shows that phosphorus concentration in effluent is below 0.5 mg/L and the key factors affecting phosphorus removal are sludge age and DO.

关 键 词：低碳城市污水 SBR法 生物除磷
