摘　　要：以河砂、粉煤灰、钢渣和煤渣为渗滤介质,模拟研究了人工快速地下渗滤系统在不同水力负荷条件下对农村生活污水中主要污染组分的处理效果。结果表明,系统对污染物的平均去除率随水力负荷的增加呈现先升高后下降的趋势;在水力负荷为1.6 m/d时,系统对污染物的平均去除效果最佳,对总磷、氨氮和COD的去除率分别为66.73%-90.06%、26.04%-89.32%和11.76%-91.51%。River sand,fly ash,steel slag and coal cinder were chosen as infiltration medium to simulate the artificial fast subsurface infiltration system under three different hydraulic loading conditions,and then the removal effect of pollutants from rural sewage by this system was investigated. The results showed that the average removal rate of pollutants increased first and then decreased with the hydraulic loading increasing; when the hydraulic loading was 1.6 m/d,the average removal rate of all pollutants was the best,and the removal rate of the TP,NH3-N and COD was 66.73%-90.06%,26.04%-89.32% and 11.76%-91.51%,respectively.
