摘　　要：[目的]对山区生活污水进行无动力生物、生态处理。[方法]针对山区具有地势落差的特点,采用"厌氧+跌水充氧接触氧化+生态塘+人工湿地"组合工艺,研究山区生活污水中COD、NH4+-N、TN、TP的去除效果。[结果]组合工艺对生活污水中COD、NH4+-N、TN、TP有很好的去除效果,平均去除率分别达62%、96%、84%、87%以上,平均出水浓度分别为59、0.83、3.99、0.19 mg/L。该工艺在山区、丘陵地带依山而建,可以实现无动力消耗运转,特别适合在山区、丘陵地带推广使用。[结论]该研究为山区丘陵地带生活污水的处理提供了依据。[Objective] The study aimed to treat rural sewage in mountainous areas by using bio-ecological combined process without power.[Method] According to the characteristics of terrain gap in mountainous areas,the combined process of ＂anaerobic pond ＋ waterfall aeration contact oxidation ＋ ecological pond ＋ constructed wetland＂ was applied in the treatment of rural sewage in mountainous areas,and the removal effects of COD,NH4＋-N,TN and TP in rural sewage were studied.[Result] The combined process had good removal effects on COD,NH4＋-N,TN and TP in rural sewage,and the average removal rate reached above 62%,96%,84% and 87% respectively,while the average concentration in the effluent was 59,0.83,3.99 and 0.19 mg/L respectively.The combined process built in mountainous areas could run without power,and be popularized in mountainous areas suitably.[Conclusion] The research could provide references for the treatment of rural sewage in mountainous areas.
