摘　　要：传统的污水慢速渗滤土地处理系统以污水的深度处理和利用为主要目标,水力负荷较小。试验对传统的土地处理系统进行改进,在土壤1 m深处设置排水系统,增大系统水力负荷。试验结果表明,在大水力负荷情况下,改进的污水慢速渗滤土地处理系统对污染物有较好地去除效果,出水水质优良。除总氮外各指标浓度均满足《地面水环境Ⅲ类水域水质标准》要求。Traditional slow rate land treatment system was mainly used to treat sewage and make use of water resource, so hydraulic load of this kind of system was low. A kind of improved method that added a drainage system at lm depth of land was introduced in this paper to enhance hydraulic load. Experimental results indicated that the disposal effect of contaminations of improved slow rate land treatment system was fine and that water quality discharged from system was fine and satisfied with the standard listed in Ⅲ surface water quality standard except total nitrogen index.
