填埋是城市固体废物处理的最常见方式之一。有机废物的降解会产生甲烷和其他填埋气体，大大加剧全球变暖。然而，在进入大气之前，部分产生的CH4在穿过垃圾填埋场覆盖层时会被氧化。本文研究了不同类型堆肥作为填埋场覆盖物时甲烷的氧化速率。研究了培养时间、含水率和温度对不同类型堆肥甲烷氧化能力的影响。结果表明，水分含量和温度对甲烷氧化的影响具有时间依赖性。最大的氧化速率观察到的水分含量范围从45%至110%（干重基础），而最佳温度范围从15至30摄氏度。(c)2005爱思唯尔有限公司保留所有权利。
Landfilling is one of the most common ways of municipal solid waste disposal. Degradation of organic waste produces CH4 and other landfill gases that significantly contribute to global warming. However, before entering the atmosphere, part of the produced CH4 can be oxidised while passing through the landfill cover. In the present Study, the oxidation rate of CH4 was Studied with various types of compost as possible landfill cover. The influence of incubation time, Moisture content and temperature on the CH4 oxidation capacity of different types of compost was examined. It was observed that the influence of moisture content and temperature on methane oxidation is time-dependent. Maximum oxidation rates were observed at moisture contents ranging from 45% to 110% (dry weight basis), while the optimum temperature ranged from 15 to 30 degrees C. (c) 2005 Elsevier Ltd.
