摘  要：
[目的]研究不同处理技术的净化效果,探索因地制宜、应用高效的生态综合治理技术。[方法]以农村生活污水为研究对象,通过分析不同处理方式对污染物的净化效果,提出不同生物生态治理措施优化筛选的科学参考。[结果]沟塘内水生植物对TN、NH_4~+-N、TP均具有较好的去除效果,停留时间为90 d时平均去除率分别为77.8%、94.3%和78.0%,但对COD_(Mn)去除率仅在35%～40%。厌氧-缺氧-好氧-湿地组合处理工艺中A~2/O工艺段对TN、NH_4~+-N、TP和COD_(Mn)的平均去除率为23.4%、48.6%、56.3%和30.7%,人工湿地对污水中氮、磷均具有较好的去除效果,出水TN、NH_4~+-N浓度分别稳定在0.66和0.25 mg/L,TP浓度基本维持在0.03～0.15 mg/L,对COD_(Mn)的去除效果并不显著,各项污染物指标平均去除率依次为97.7%、89.0%、86.2%和53.1%。[结论]将生物方法和生态工程有机结合的组合处理技术能够达到稳定的脱氮除磷功效,在农村生活污水处理领域具有很高的推广应用价值。

摘  要：
[Objective]To study the purification effect of different treatments, and explore an efficient ecological comprehensive management technology in line with local conditions.[Method]Taking rural domestic sewage as the research object, this paper analyzed the purification effect of different treatment methods on pollutants, and put forward the scientific reference for optimizing and screening different biological ecological treatment measures.[Result]The aquatic plants in the ditch pond had good removal effects on TN,NH_4~+-N and TP.When the residence time was 90 d, the average removal rates were 77.8%,94.3% and 78.0%,respectively, but the removal rates of COD_(Mn) were only between 35% and 40%.The average removal rates of TN,NH_4~+-N,TP and COD_(Mn) in A~2/O process were 23.4%,48.6%,56.3% and 30.7%,respectively.The constructed wetland had a good removal effect on nitrogen and phosphorus in wastewater, the concentration of TN and NH_4~+-N in the effluent was stabilized at 0.66 and 0.25 mg/L,respectively, and TP concentration was basically maintained between 0.03-0.15 mg/L.The removal effect of COD_(Mn) was not significant, the average removal rates of TN,NH_4~+-N,TP and COD_(Mn) were 97.7%,89.0%,86.2% and 53.1%,respectively.[Conclusion]The combination of biological methods and ecological engineering can achieve a stable removal efficiency of nitrogen and phosphorus, which has high application value in the field of rural domestic sewage treatment.
