摘　　要：传统的污水处理厂以去除BOD5、SS为目标,除磷能力较差。为此,开展了潜流碎石床湿地去除二级生化处理出水中磷的研究。结果表明,当进水TP为1.80 mg/L时出水为0.27mg/L,去除率为85%。与此同时,对BOD5、COD、SS、NH3-N等也有一定程度的去除,出水水质基本满足《生活杂用水水质标准》(CJ/T 48—1999)。In conventional wastewater treatment plant, the purpose is mainly the removal of BOD5 and SS, with poor capacity in phosphorus removal. Therefore, the study was made on the use of subsurface crushed stone wetland for phosphorus removal from the effluent of secondary bio-chemical treatment process. The result indicates that the effluent TP is 0.27 mg/L at influent TP of 1.80 mg/L with removal rate of 85%. Meanwhile, some BOD5, COD, SS, NH3 - N can also be removed. The effluent quality basically meets the Miscellaneous Domestic Wastewater Quality Standard （ CJ/T 48-1999）.
