摘　　要：我国城市生活垃圾中有机物含量,特别是食品垃圾含量高,垃圾在填埋后会产生大量填埋气(LandfillGas)。甲烷是垃圾填埋场释气的主要成分之一,其温室效应作用是CO2的20倍以上。甲烷可以通过多种途径消耗,但通过土壤进行氧化仍是其最为主要和有效的消耗方式。目前国内对这方面的研究比较少。文章主要分析了氧化的机理和土壤温度、含水率、厚度以及含氮量对氧化过程的影响;介绍了国际上在氧化产物上的最新发现,从而为如何调控填埋场覆盖层条件以降低甲烷排放提供一种依据并为氧化产物的研究提供新思路。The content of organic matter in MSW, They will produce a great amount of landfill gases. especially in food waste, is very rich in China. CH4 is the main component. Its green house effect is over 20 times of CO2. CH4 can be consumed by many ways, but methane oxidation in soil is the most important and effective way. Now there are few researches on it in China. This text mainly analyses the mechanism of methane oxidation and influence factors such as temperature, humidity, thickness and nitrogen content in soil, and introduces some new discovers overseas. It will be used as reference for reducing the CH4 emission by controlling the conditions of the landfill soil cover, and will provide a new solution for methane oxidation.
