摘　　要：对南方地区垃圾渗滤液、粪便污水和城市污水水质特点进行调查分析,结果表明,混合污水主要高浓度污染物为氨氮和有机物。采用倒置A2/O工艺对混合污水进行处理,试验结果表明:采用倒置A2/O工艺,控制垃圾渗滤液、粪便污水与城市污水混合比,污染物去除效果较好,出水CODCr、NH3—N和TN可以达到《城镇污水处理厂污染物排放标准》(GB18918—2002)一级排放标准。Based on the water quality of landfill leachate,night soil sewage,and municipal wastewater in south China,it was found that the high concentration pollutants in mixed wastewater are mainly composed of NH3—N and organic matter. The inverted A2/O process was used to treat mixed wastewater. The results showed：if the inverted A2/O process was employed and the mixture ratio of landfill leachate,night soil sewage,and municipal wastewater was also controlled,the CODCr,NH3—N,and TN in effluent will satisfy the first calss of Discharge standard of pollutants for municipal wastewater treatment plant（GB 18918—2002）.
