title: [Dynamic variation of landfill gas production under different landfill treatment].
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.
