摘　　要：为了研究改良型土壤渗滤系统对某农家乐污水的净化效果,通过对传统土壤渗滤系统的改进设计,取得了较好的处理效果,化学需氧量(COD)、氨氮(NH_4^+-N)、总氮(TN)和总磷(TP)的平均去除率分别达到82.41%、91.06%、80.12%和88.59%,砂滤池出水悬浮固体(SS)的平均去除率达到了85.15%。其克服了传统土壤渗滤系统易堵塞、处理负荷低、脱氮效果差和不易反冲洗等缺陷,对于该地区农家乐生活污水治理具有推广应用价值。This study examined the purifying effect on farmhouse wastewater of a modified soil infiltration system by improving the design of a traditional soil infiltration system. The average removal rates of COD,NH_4-＋-N,TN,and TP were 82. 41%,91. 06%,80. 12%,and 88. 59%,respectively,and the average removal rate of a sand filter on SS was 85. 15%. The modified system surpasses the traditional soil infiltration system because the former＇s ease in plugging,low processing load,poor nitrogen,and difficulty in backwashing. The modified system can be widely used and applied to the region＇s rural sewage treatment.
