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.
