| Abstract: | Based on the passive air venting system developed in previous research, an up-scaled simulated system (2.4m×0.85m×3.6m) combined breathing biocover with semi-aerobic landfill was constructed. Its effect on methane oxidation capability was investigated. The results showed that the lowest O2 level kept more than 15% in the whole biocover layer (40cm) during the fast degradation phase of waste. Correspondingly, CH4 in the surface area of the biocover layer cannot be detected. Compared to the traditional cover layer, the highest CH4 concentration can be reduced by 76.5% with the introduction of the breathing biocover. Oxygen supply by thermal motive changed the distribution of CH4 and CO2 inside the cover layer. The study verified the hypothesis that methane emission can be reduced by enhancing activity of methanotrophs through supplying sufficient O2 in the cover layer. |
