摘　　要：大峪镇薛寨村是济源市西部山区,村内没有生活污水处理设施,居民日常生活产生的污水多直接排放,对周边水域及地下水造成污染。鉴于此,在薛寨村建设了农村生活污水净化工程,该工程采用“化粪池+折流厌氧反应器+三级表流人工湿地”组合工艺,系统出水水质达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A标准。实践证明,该工艺具有较好的处理效果,排水可用于农灌。本工程提升了薛寨村的环境质量,对于增加区域生物多样性、生态系统稳定性和气候调节,具有重要意义。Xuezhai Village in Datun Town is a mountainous area in the west of Jiyuan City.There are no domestic sewage treatment facilities in the village,and the sewage produced by residents daily life is mostly discharged directly,causing pollution to surrounding waters and groundwater.Therefore,the rural domestic sewage purification project was built in Xuezhai Village.The project adopts the combined process of“septic tank+baffled anaerobic reactor+three-stage surface flow constructed wetland”,and the treated effluent can meet the requirements for the first A level standard specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918—2002).The practice proves that the process has better treatment effect,and rainage can be used for agricultural irrigation.This project improves the environmental quality of Xuezhai Village,which is of great significance for increasing regional biodiversity,ecosystem stability and climate regulation.
