摘　　要：针对农村分散污水水质稳定、水量少、处理难度较小等特点,结合农村地区经济发展和管理的实际,设计制造并运行生物接触氧化-潜流人工湿地小型一体化处理设备进行处理生活污水的试验研究,通过改变水力停留时间和曝气周期,考察组合工艺对于污水中COD、氨氮、总磷的处理效果。结果表明,当水力停留时间1 d,曝气周期1. 5 h,对COD、氨氮、总磷的平均去除率分别为90%,85%,63%,出水能达到一级A排放标准。The scattered sewage quality in rural areas is stable,less water and less difficult to handle and so on,combined with the reality of economic development and management in rural areas,designed and manufactured biological contact oxidation-subsurface flow constructed wetland combination process of small integrated processing equipment for the treatment of domestic sewage test study.Concentrated inspection of the combined process for the sewage COD,ammonia nitrogen,total phosphorus treatment effect.Respectively,changed the influent flow and aeration cycle.The results showed that when the HRT is 1 d,the aeration period 1.5 h,COD,ammonia nitrogen,total phosphorus removal rate were 90%,85%and 63%.The effluent can partly reach the level of A emission standards.
