NOVELTY - Comprehensive treatment and utilization of leachate in dump site comprises setting a single or multiple circular regions in the refuse landfill; at the center of the circle, drilling a rich well, and drilling rich wells connected to the rich well at the center of the circle at its circumference; extracting the dump leachate from the rich well, pumping onto ground, filtering and removing particle impurities; concentrating filtrate and then doping into residua formed by burning the garbage as the raw material of light wall body material; and drying and burning the particle impurities.    USE - Method for comprehensive treatment and utilization of leachate in dump site (claimed).    ADVANTAGE - The method solves pollution of the leachate in the dump site and saves large investment of culture of the engineering bacteria; has simple mating of the device, energy saving, high in efficiency and low cost, which is applied to industrialization, automation, small investment and large effect result; and has environmental benefits, good application and popularization value. The dump site can be reutilized as the field in a short time.    DETAILED DESCRIPTION - Comprehensive treatment and utilization of leachate in dump site comprises setting a single or multiple circular regions in the refuse landfill, distance between the circular regions neighboring being 6-10 m; at the center of the circle, drilling a rich well whose depth is 60-80% that of the refuse landfill, and drilling rich wells connected to the rich well at the center of the circle at its circumference, the depths of the rich wells being 50-70% depth of the rich well at the center of the circle; extracting the dump leachate from the rich well, pumping onto the ground, filtering and removing the particle impurities; concentrating the filtrate and then doping into the residua formed by burning the garbage as the raw material of light wall body material; and drying and burning the particle impurities and obtaining the residua.
