THE CONSTRUCTION METHOD FOR VENTILATION RECLAIMED INSTITUTION OF LANDFILL USING AIRDOME

摘要

A construction method for using the aerobic landfill an of air dome to pad is arranged to cut away leachate by rainwater by the air dome being mounted in landfill liner, it prevents from generating foul smell and scatters dust, it passes through one pressure fan of installation and the deaeration pipe in landfill liner, promote incipient stability by decomposing waste material aerobicly, waste processing cost is reduced by one leaching liquid pipe of installation and a leachate sump and grazioso makes a scene and pass through with open arms the germination condition environment-of fixed plant in the presence of all. A construction method for using the aerobic landfill an of air dome to pad includes the following steps:: excavating a landfill site and forms an inclination angle of filling (1); Due to the leachate sump of the landfill site of excavation, device non-woven fabrics, a bentonite pad, a cut film and a geocomposite installation underground water on base in order, the road surface of rubble on bottom (3) and road surface bentonite mixtures soil, then tamps; It is mounted on the road surface of a cut film on bottom, a geocomposite and a leaching liquid pipe and rubble; Execute perforation processing landfill site, device anchor, installation one air dome film (4) and cable, one gate of installation, a draught fan and a generator and the outside air for being sent in air dome uses draught fan; Leachate removal conduit and a leachate sump are quickly installed to discharge leachate; It connects a deaeration pipe and air is instructed in the air dome to outside to a ventilation blower and as a passage of air and exhaust gas; Waste material is accumulated in landfill site and rise sends air in deaeration pipe positioned at the leachate removal facility and one pressure fan of installation of the lowermost part of landfill liner and buries the waste gas filled out to controlling; Aerobic landfill liner is covered with a degassing layer in order, a cutoff layer, cut film, a drain layer, a layer of plants and a lattice block arrangement of reinforcement lawn outstanding.
