生活垃圾生物处理包括卫生填埋和高温堆肥，均产生大量温室气体，其中甲烷是重要组成。如果控制不当，会以无组织排放形式污染环境。本项目以《基于氮素损失原位控制的堆肥中GHG形成机理及减排研究》和《基于 N 素损失原位控制的厨余垃圾堆肥过程中臭气产生规律和控制机理》两个基金为基础，遵循原位控制与减排新理念，进行基于甲烷氧化菌构建的覆盖材料为基础的，填埋场甲烷氧化覆盖材料甲烷去除过程及影响因素研究，明确覆盖材料的物理结构特性与甲烷或氧气等气体扩散的内在联系，分析碳、氮、其他化学物质以及外援性微生物对材料中甲烷氧化类微生物种群结构及甲烷生物去除关键酶的影响，阐明材料中甲烷氧化菌系的结构特性及其甲烷处理能力的关系，在上述基础上，提出堆肥及填埋场甲烷氧化覆盖材料的选择机制及性能强化机制，在低耗、经济的条件下进一步优化生活垃圾生物处理过程甲烷减排技术。

The bio-treatment methods of MSW include sanitary landfill and composting, however, the two methods both produce a great deal of greenhouse gas, and methane is the most important one. Once without the proper disposal, the methane emission would be out of order, and polluted environment seriously. This research was based on the two funds, which were < The research of GHG Formation Mechanism and Reduction Based on In-Situ Control of Nitrogen Loss in Composting> and <The Produce Principle and Control Mechanism of Odor Based on In-Situ Control of Nitrogen Loss in Kitchen Waste Composting>, and followed the new concept of in-situ control and reduction, and then processing the research of removing methane from methane oxidation cover material as well what were the effective factors in this process on the basis of methane oxidation bacteria building the structure of cover material, determining the physical characteristics of cover material and the inner connection of methane and oxygen diffusion, analyzing how carbon, nitrogen and other chemical substances and Inoculating Microbes affected the process of methane oxidizing microbes and methane species wiping out critical enzyme, clarifying the relation of methane oxidation bacteria structural characteristics and methane disposal capability in cover material, at last, proposing how to select and Strengthen Functional mechanism of methane oxidation material and optimizing the methane reduction technical in condition of economical and low consumption on in-situ MSW landfill.
