摘　　要：通过在露天试验场建立地下渗滤系统试验装置,研究了西安地区地下渗滤系统处理生活污水的效果。试验所采用的水力负荷为2.4 cm/d。研究结果表明,系统在运行30天后达到熟化,熟化后该系统对COD、总氮以及氨氮的平均去除率分别为91.4%、29.5%和98.6%;出水COD、总氮以及氨氮的平均浓度为16.8 mg/L3、2.78 mg/L和0.41 mg/L;不同时段COD和氨氮的出水浓度起伏不定,但总的趋势是下降的,系统对当天COD和氨氮的系统去除率分别为89.0%和93.6%。所以,地下渗滤系统在西安地区处理生活污水效果良好。This paper deals with the effect of Subsurface Wastewater Infiltration System for Domestic Sewage Treatment in Xi＇ an through the establishment of subsurface infiltration system testing device in the open testing field. The hydraulic capacity adopted in the experiment is 2.4 cm/d. The results of study indicate that the system reached the mature after 30 days. The average removal efficiencies in COD, total phosphorus and NH4^＋-N is 91.4%, 29.5% and 98.6%, with average effluent concentrations of COD, total phosphorus and NH4^＋-N being 16.8 mg/L, 32.78 mg/L, 0. 41 mg/L. In different time sections, the effluent concentrations of COD and NH4^＋-N was under fluctuation, but the general trend was on the decline. The average removal efficiencies of COD and NH4^＋-N by the system in the current clay were 89.0% and 93.6%. As a result, the effect of subsurface wastewater infiltration system to dispose the domestic sewage was excellent.
