摘　　要：采用地埋式一体化生物滤池工艺处理农村生活污水。该工艺通过设置前置缺氧池进行反硝化脱氮,通过拔风和溅水来强化充氧效果,实现了碳氧化及硝化。中试结果表明,该工艺对COD的平均去除率达63.1%,对NH4+-N的去除率为92.2%,对TN的去除率为68.6%,对TP的去除率为47.5%,出水水质达到了《城镇污水处理厂污染物排放标准》(GB18918—2002)的一级标准。该工艺具有节能、高效和简易的特点,适于在居住分散的农村地区推广。The buried integrated biofiher process was used to treat rural domestic sewage. The carbon oxidation and nitrification were carried out through denitrification in pre-anoxic pond and enhanced oxygenation by ventilating and splashing. The pilot test results show that the average removal rates of COD, NH4^＋ - N, TN and TP are 63.1%, 92.2%, 68.6% and 47.5% respectively. The effluent quality achieves the first class criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002）. The process has characteristics of energy-saving, high efficiency and simple operation, thus it is suitable to be generalized in rural areas inhabited dispersedly.
