Abstract

|
|
Stabilization of industrial wastes landfill was investigated, comparing landfill gases(LFG) which were generated from a land site with those from three sets of lysimeter. Lysimeter-packing wastes consisted of 7.2∼17.0 wt.% of combustible component and theoretical gas production rate with their elemental analysis was 0.31∼0.49 ㎥/kg-dry waste. Gas production rate(㎥/kg-dry waste) from lysimeter A, B and C was 0.0009, 0.014 and 0.0067, respectively, and different from each other according to the landfill period of wastes. Applying the Landfill Air Emissions Estimation model of EPA to the landfill site of this research, the production rate of CH_4 is 1.963 × 10 exp(7) ㎥/year in 1998 and reaches to maximum in 2000. Methane and carbon dioxide accounted for 0∼10.2% in gases discharged from gas discharge pipes in the landfill site and were not detected in efflux gases on the landfill surface.
