摘要

PURPOSE: To provide a leachate treatment method which stores leachate generated from waste landfill in a leachate amount control facility by using a leachate recovery facility and recirculates the leachate in the leachate amount control facility into the landfill, thereby increases moisture content in the landfill to promote biodegradation of leachate by microorganisms. CONSTITUTION: The method for treating leachate generated from a waste landfill(1) comprises: a step(a) of installing a leachate recovery facility(2) for recovering leachate generated from the waste landfill, a leachate amount control facility(3) for controlling an amount of the recovered leachate and a leachate recirculation facility(5) for recirculating leachate of the leachate amount control facility into the waste landfill; a step(b) of purifying leachate by recirculating leachate stored in the leachate amount control facility into the waste landfill by the leachate recirculation facility; a step(c) of forming a vegetation soil layer(13) on an area distanced from the waste landfill in a prescribed distance, and planting vegetation for evapotranspiration(16) on the surface of the vegetation soil layer; and a step(d) of injecting leachate purified in the step(b) into the vegetation soil layer so that the action of evapotranspiration is performed by vegetation on the surface of the vegetation soil layer.
