摘要
湖北某山区农村生活污水成分简单、污染物浓度低,根据当地地势及生态环境,适于采用人工湿地结合厌氧和跌水接触氧化的复合处理工艺。通过改造原有池塘、利用自然斜坡优化设计了厌氧池、跌水接触氧化池和潜流人工湿地,出水水质优于GB 18918—2002《城镇污水处理厂污染物排放标准》一级B类排放标准。运行结果表明:人工湿地组合工艺处理效率高,投资少,运行维护简单,可作为山区农村生活污水处理的重要方法。
A combined process involving anaerobic,waterfall aeration contact oxidation and constructed subsurface flow wetland system was suitable for treatment of a mountain area rural domestic sewage characterized by simple composition and low pollutant concentration, according to local terrain and ecological environment. The anaerobic pool, waterfall aeration contact oxidation tank and constructed subsurface flow wetland were optimizationally designed by transforming the original pond and using the natural slope. The effluent quality was better than the level B discharge standard demand of ＂Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant＂ （GB 18918-2002）. The operation results showed that the combined process has high treatment efficiency, low investment, simple operation and maintenance, which can be an important option for rural domestic sewage treatment.
