摘要 为研发适用于我国农村的分散式污水处理装置,采用厌氧+跌水曝气+人工湿地组合工艺对农村生活污水进行处理,考察组合工艺对COD、TN、TP、NH4+-N、SS 5个常规指标的去除效果及对各指标的沿程去除情况。结果表明,组合工艺对COD、TN、TP、NH4+-N和SS的平均去除率分别为74.5%、 57.2%、 59.5%、 59.00%和91.6%。人工湿地对COD、TN、TP和NH4+-N的去除率最大,分别为31.0%、36.7%、43.9%和30.0%;而厌氧反应池对SS去除贡献率最大,为40.3%。该组合工艺处理农村生活污水具有良好的处理效果,且装置运行能耗低,利于推广应用。 To develop the decentralized sewage treatment devices suitable for rural areas in China, a combined process of anaerobic tank,drop-aeration and constructed wetland was developed to treat the rural domestic sewage. The removal rates of five conventional indexes(COD, TN, TP, NH4+-N and SS) and their changes along the process were studied. The results showed that their removal rates were 74.5%, 57.2%, 59.5%, 59.00% and91.6%, respectively. The constructed wetland had the highest removal rates of COD, TN, TP and NH4+-N, which were 31.0%, 36.7%, 43.9% and 30.0%, respectively, while anaerobic tank had the largest SS removal rate of 40.3%. The combined process has a good performance on the rural domestic sewage treatment with low energy consumption, which is conducive to its popularization and application.
