摘要: 填埋是国内外城市生活垃圾处理的一种主要方式.垃圾填埋场是温室气体氧化亚氮(N2O)和甲烷(CH4)的重要排放源.作为一种高效痕量的温室气体,N2O具有极高的潜在增温效应,其每分子潜在的增温作用是二氧化碳(CO2)的296倍.而且N2O能在大气中长期稳定存在,对臭氧层具有较强的破坏作用.本文针对垃圾填埋场N2O排放的控制研究,概述了垃圾填埋处理过程中主要排放源的N2O排放及其影响因素,提出了现阶段适应我国垃圾填埋场N2O排放控制的一系列措施,并展望了垃圾填埋场温室气体N2O排放控制理论和技术的研究方向.

Abstract: Landfill is one of the main approaches for municipal solid waste treatment, and landfill site is a main emission source of greenhouse gases nitrous oxide (N2O) and methane (CH4). As a high-efficient trace greenhouse gas, N2O has a very high warming potential, with a warming capacity 296 times of CO2, and has a long-term stability in atmosphere, giving greater damage to the ozone layer. Aiming at the researches in the control of N2O emission from municipal solid waste landfill sites, this paper summarized the characteristics and related affecting factors of the N2O emission from the landfill sites, and put forward a series of the measures adaptable to the N2O emission control of  present municipal solid waste landfill sites in China. Some further research focuses on the control of N2O emission from the landfill sites were also presented.

Key words: municipal solid waste landfill site, N2O emission, greenhouse gas.
