Dynamic variation of landfill gas production under different landfill treatment

Abstract

Abstract: Based on the landfill principles,large scale installations of anaerobic and semi-aerobic landfills were established,with the concentrations of CH₄,O₂ and CO₂ detected regularly.The results showed that the average CH₄ concentration in semi-aerobic and anaerobic landfill installations was 7%～13% and 35%～50%,respectively,indicating the better effect of semi-aerobic landfill in reducing CH₄ production.The CH₄ and O₂ concentrations in the two landfill installations all presented obvious spatial layer effect,i.e.,under-layer > middle layer> upper layer for CH₄,while upper layer > middle level > under-layer for O₂.

Key words: Semi-aerobic, Municipal solid waste, Landfill gas, Methane
