매립깊이에 따른 폐기물매립시설 안정화 평가

Abstract

In this study, the stabilization of the waste landfill in the sanitary landfill currently in operation was evaluated according to the landfill depth. The results of property survey of landfill waste ratio of soil is the highest according to the landfill depth, vinyls from 23.6 %~37.5 %, 22.4 %~23.3 %, 15.2 %~19.3 % and 15.8 %~13.2 % for each landfill depth. The ratio of C according to the landfill depth was the highest at 35.53 %, the landfill period 3~5 years, landfill depth 15 m and 5 m at 5~10 years and 10~15 years, showing a ration of 26.21 % and 18.29 %. The CH₄ concentration decreased depending on landfill period(3~5 years, 5~10 years, 10~15 years, more than 15 years), as investigated in 52.5 %, 38.3 %, 29.4 % and 20.1 %. Estimate the stabilization by landfill depth (5 m, 10 m and 15 m) according to organic matter and C/N ratio as a logarithmic function, about 40 years, 43.6 years and 36.6 years. Linear function was found to take 26 years, 26.6 years and 23.9 years.
