PURPOSE: An aerobic landfill method without leaking leachate using natural wind is provide, which is characterized in that the method can maintain aerobic condition by supplying natural wind in inner landfill and can make a stabilization period decreased. Also, the method can prevent leachate from leaking by using the collecting and draining system of leachate. The methane gas generated from anaerobic landfill is stronger twenty one times than CO2 on greenhouse effect, but aerobic landfill demands high cost in comparison with anaerobic landfill. CONSTITUTION: The system consists of the follow parts: a collecting and draining layer for leachate(1), a manifold pipe using with holes to collect and drain leachate(2), a gas collecting pipe(3), a treatment plant for leachate(5), a final soil cover layer(6), an air-supply pipe(8), a vertical air-supply pipe(9), a leachate collecting well(10), an air blower(11) and a direction control impeller(13). The device has advantages of air supply regardless of direction, a powerless blower and the treatment of leachate in landfill by recirculating through the gas collecting pipe(3). |
