摘要: 为解决高寒地区农牧民定居点生活污水处理存在水质浓度低、运行费用高和无专业运营管理人员等问题,笔者拟采用土地渗滤系统进行高寒地区农牧民定居点生活污水处理试验,分析不同条件时的去除效率,确定最佳工艺运行参数。试验结果表明,高寒地区地下渗滤系统最佳工艺参数:填料配比为1:2,表层土厚度为15 cm,水力负荷为7 cm/d。地下渗滤系统对生活污水中的污染物具有较好的去除效率,出水能够达到城镇污水排放一级A标准。

Abstract: The paper aims to solve the problems in disposing domestic sewage at farmers and herdsmen settlement, such as low water quality concentration, high cost and no professional manager and so on, land filtration system was intended to do experiment in living sewage treatment in alpine region, analyzed the removal efficiency at different conditions and determined optimum operating parameters. Experimental results showed that: the best process parameters in subsurface infiltration system were: the ratio of filler was 1:2, the surface soil thickness was 15 cm, hydraulic load was 7 cm/d. Subsurface wastewater infiltration system has good efficiency in removing pollutants in sewage and the effluent water can reach A standard urban sewage discharge standard level.
