摘　　要：采用生物生态技术处理农村生活污水,将“化粪池+调节池+跌水复氧+水平潜流人工湿地+稳定塘”组合工艺应用于河南省灵宝市某村生活污水处理。连续运行中发现,该工艺具有较好的处理效果,COD、NH_(3)-N、TP等主要指标的平均去除率分别为72.8%、58.2%、55.1%,出水水质满足《河南省农村生活污水处理设施水污染物排放标准》(DB 41/1820-2019)二级标准,经处理的污水进入稳定塘暂存,并进行资源化利用不外排。本工程可为相似区域农村生活污水处理的技术选择和运行提供参考。Bio-ecological technology is used to treat rural domestic sewage and applied to a village in Lingbao City,Henan Province.A combined process of“septic tank+regulating tank+falling water reaeration+horizontal subsurface constructed wetland+stabilisation pond”is adopted.The practice shows that the process has good treatment eff ect in 90 days of consecutive operation,and the average removal rates of COD,ammonia-nitrogen and total phosphorus are 72.8%,58.2%and 55.1%,respectively,whilst the system effl uent meets the requirement of Class II specifi ed in Henan Provincial local standard:《Standard for water pollutant discharge from rural domestic sewage treatment facilities》(DB 41/1820-2019).After treatment,the effl uent will enter the stabilisation pond for temporary storage and be resourcefully utilised afterwards.This project could provide a reference for the technical choice and operation of rural domestic sewage treatment in similar areas.
