lmproved Semi-Aerobic Stabilization landfill Method with Expansion of aerobic area by Multi-point Surfacewater and leachate Switching Drainage System

摘要

PURPOSE: An expanded semi-aerobic landfill method by multi-point surface water and leachate switching drainage system which can drop the water level of leachate by performing the functions of exclusion of surface water and leachate by turns and can decompose and stabilize wastes by increasing aerobic area in landfill site. CONSTITUTION: The equipment comprises a small end(51) which is inclined to bank(55), a rainwater drainage(61) for creating waterway at the upper part of small end, a securing means for inner space for the flow of fluid and the inflow/outflow of air, a drainage pipe(71) which is connected with rainwater drainage. The securing means for inner space is composed of perforated pipe(81) and one or more sorts of gravel or broken stone(91) are covered at the upper part of the securing means for inner space.
