摘　　要：论述了北方某镇采用无动力处理技术处理农村生活污水的方法,工艺流程为新型化粪池-人工湿地-氧化塘工艺。运行结果表明,工程出水中污染物日均浓度COD为35~55 mg/L、BOD5为10~20 mg/L、SS为5~18mg/L、氨氮为3~5 mg/L,均能达到《农田灌溉水质标准》（GB 5084-2005）中蔬菜a标准。处理后的出水用于周边农田灌溉,既治理了污染,又节约了资源,是绿色、低碳城镇建设的一个典范,非常适合北方乡镇新农村建设的生活污水处理和利用。Unpower treatment technology dealing with rural domestic sewage in a northern town was researched in the paper.The technique process was new septic tank-Wetland-oxidation pond.The operation results showed that the average concentrations of pollutants COD in water was 35~55 mg / L,BOD5 was 10~20 mg / L,SS was 5~18 mg / L,ammonia nitrogen was 3~5 mg / L,All reached vegetable a standard in the GB 5084-2005 irrigation water quality.Treated effluent could be used for irrigation of near farmland witch not only controled the pollution but also saved resources.It is a model for green-low carbon cities and towns and very suitable for the treatment and utilization of domestic sewage in new countryside construction of northern town.
