There is a barrier between reservoir and atmospheric water of basin margin forming reducing environment with low sulphate which is favorable to methane bacteria activity.
储层与盆地边缘大气水渗滤带隔绝,形成了低硫酸盐的还原环境,有利于甲烷菌活动。
The organic material will be anaerobic decomposed by methane bacteria when municipal solid waste (MSW) is processing in landfills, thus methane will be emitted to the atmosphere.
