Abstract
The functional relationship between the generation rate coefficient and temperature was developed for quantitative prediction of the temperature effect in this paper. The methane production of the landfill was predicted under the condition of the seasonal variation. The results showed that considering the temperature effect, the methane production is higher than the methane production without temperature effect of the 0.14×106 m3~0.28×106m3.With the depth increasing, the effect of the atmospheric temperature fluctuation on the temperature change of the landfill was weakened. The temperature has a significant effect on the methane production in the landfill. The temperature effect should be considered when simulate the long time effect of the landfill methane production.
Highlights
It is important to study the prediction of methane production in landfill for landfill gas reuse
The results showed that the refuse which was near the surface was influenced bigger by the outside temperature
The methane production was impacted by the variation of the temperature in landfill
Summary
It is important to study the prediction of methane production in landfill for landfill gas reuse. The methane generation in landfill was usually described by the experimental and numerical investigations. G. De Gioannis et al (2009) investigated the estimation of the variation of the potential gas generation capacity L0 by mechanical biological treatment of MSW[2]. In this paper, the gas generation rate model which considered the temperature effect was given, simulating the law of the gas production under the influence of temperature in different depths. The gas productions of methane under the consideration of the temperature effect or not were compared and analyzed.
