摘　　要：城市固体废弃物作为重要的碳源,其不同的处理方式碳排放量的差异显著。以东莞市某垃圾焚烧发电厂有限公司为例,分析比较了焚烧发电、卫生填埋、生物堆肥处理城市固体废弃物带来的碳排放量。结果表明,单位垃圾处理碳排放产生量分别为焚烧发电0.61t CO2/t(二期为0.10 t CO2/t),标准卫生填埋1.02 t CO2/t,生物堆肥0.10 t CO2/t,生物堆肥产生的碳排放量最少,其次为焚烧处理。此外,垃圾焚烧发电减排量最高,达38.0%;卫生填埋减排量达14.9%,但仍然具有较大的CO2排放量;生物堆肥产生的CO2(折算后)较焚烧发电和卫生填埋少。通过改进工艺和选择适宜的城市固废处理方式,可减少温室气体排放量。As important anthropogenic sources,different municipal solid waste（MSW） processing model will lead to carbon emission difference.With one waste incineration power generation plant in Dongguan City as an example,the carbon emission divergence from MSW processed by incineration power generation,sanitary landfill and biological treatment was analyzed.The results showed that carbon emission of incineration power generation,sanitary landfill and biological composting is 0.61（the second phase is 0.10 t CO2/ t）,1.02,0.10 t CO2/ t.Moreover,carbon emission reduction of incineration power generation is 38.0%,which is most significant,and that of sanitary landfill is 14.9% which was still with high carbon emission characteristic,carbon emission from biological treatment was the lowest.Improving the technique and selecting suitable MSW modes could reduce greenhouse gas emission.
