Abstract: Through indoor simulation experiments, the methane oxidation properties of typical landfill cover materials were compared, and the impacts of cultivation temperature, moisture content, and inoculation measures on the methane oxidation performance were further analyzed. The results showed that the order of methane oxidation capacity was: aged refuse > aged cover soil > compost > new cover soil. Methane oxidation rate of cover materials was dramatically affected by moisture content, the degree of which was related with the physical properties of tested materials, and the optimum moisture content was about 25％. Meanwhile, with temperature rising, methane oxidation rate of tested materials increased first and then decreased, and the best cultivation temperature was about 25 ℃. In addition, the methane oxidation rate increased significantly after the new cover soil was inoculated with aged refuse, and the inoculation proportion was recommended as 1:10 (aged refuse : new cover soil, m/m).
