填埋气体由甲烷（CH 4）和（CO2）以约（60% - 40%）的比例组成，由此甲烷对温室效应的影响比二氧化碳高约25倍。垃圾填埋场覆盖层中发生的细菌甲烷氧化有助于减少垃圾填埋场的气候活性排放。这一贡献提出了一个理论和数值方法来模拟细菌甲烷氧化的耦合过程。介绍了一种基于多孔介质理论和混合物理论的等温两相模型以及耦合有限元计算概念。（© 2013 Wiley‐VCH Verlag GmbH & Co. KGaA，魏因海姆）
Landfill gas is composed of methane (CH4) and (CO2) at a ratio of about (60% – 40%), whereby the impact of methane on the greenhouse effect is about 25 times higher than that of carbon dioxide. Bacterial methane oxidation, taking place in the landfill cover layer, helps to reduce the climate active emissions from landfill sites. This contribution presents a theoretical and numerical approach to model the coupled processes of bacterial methane oxidation. An isothermal biphasic model based on the Theory of Porous Media (TPM) and Mixture Theory is introduced as well as the coupled finite element (FE) calculation concept.
