摘　　要：为了评估密集型村镇生活垃圾在不同处理模式下对环境的影响,以全生命周期评价方法作为研究手段,选取湖北麻城市的密集型村镇作为研究对象,对不同模式的处理过程中所产生的各类污染,按照全球变暖、酸化、富营养化、光化学臭氧合成、生态毒性5项环境影响类型进行环境影响潜值核算,并通过比较总环境影响潜值,给出了适宜的密集型村镇生活垃圾处理模式和建议。结果表明麻城市村镇生活垃圾处理的现有模式、二分类模式(人口密集区)、二分类模式(人口稀疏区)、三分类模式(人口密集区)和三分类模式(人口稀疏区)的环境影响潜值分别为4.75×10^(−2)、7.91×10^(−2)、1.50×10^(−2)、2.77×10^(−2)、1.54×10^(−2)。可以看出,对密集型村镇生活垃圾进行筛分减量、分类处理具有显著的节能减排效果,同时对环境更加友好且有助于降低经济成本。To evaluate the environmental impact of densely populated village and town domestic waste under different treatment modes,the full life cycle assessment approach was used as a research tool.The densely populated village and town of Macheng in Hubei Province was the focal point of the investigation.The various types of pollution generated during the treatment process under different modes were calculated for their potential environmental impact according to five environmental impact categories:global warming,acidification,eutrophication,photochemical ozone synthesis,and ecological toxicity.Finally,by comparing the total potential environmental impact under different modes,suitable densely populated village and town domestic waste treatment modes and suggestions were given.The results showed that the potential environmental impact of Macheng’s village and town domestic waste in the existing mode,two-category mode(populated area),two-category mode(sparsely populated area),three-category mode(populated area)and threecategory mode(sparsely populated area)were 4.75×10^(−2),7.91×10^(−2),1.50×10^(−2),2.77×10^(−2),and 1.54×10^(−2),respectively.It can be seen that screening and reducing densely populated village and town domestic waste has a significant effect on energy conservation and emission reduction while being more environmentally friendly and helping to reduce economic costs.
