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。该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 land-treatment-system with slow rate xs mainly usea to treat sewage and make use of water resources. The hydraulic load of this kind of system is low. A kind of improved method that added a drainage system at lm depth in soil was introduced in this paper to enhance the system hydraulic load. Experimental results indicated that the disposal effect of contaminations of improved land-treatment-system with slow rate run well and that the discharged water quality treated by the system was satisfied and could meet the standard of surface water quality standard Ⅱ except total nitrogen index.
