运用生命周期理论对目前绥德县生活垃圾产生量、组分以及卫生填埋处理现状进行较为系统的评价,并对绥德县生活垃圾运输过程中的能耗和进入填埋场后产生的填埋气体进行清单分析,通过计算填埋气体中各种气体的排放量得出其对环境的影响潜力,结果表明:绥德县生活垃圾卫生填埋场处理垃圾产生的主要污染气体为CH4和CO2,生活垃圾卫生填埋处理方式对温室效应产生的环境影响潜力为5.7×10-2kg/(人·a),酸化的环境影响潜力为2.1×10-3kg/(人·a),富营养化的环境影响潜力为1.7×10-3kg/(人·a).%Life cycle theory was used to systematically evaluate the current Suide county's domestic garbage output,composition and sanitary landfill treatment status.We made inventory analysis on energy consumption during transporting and gas generated after entering landfills in the process of landfill.The potential impact on the environment was obtained through calculating the emission of various landfill gases.The results showed that the main pollution gases were CH4 and CO2 which produced from domestic garbage sanitary landfill in Suide county.The environmental impact potential produced from garbage landfill disposal to greenhouse effect was 5.7 × 10-2 kg/(person·a),acidification was 2.1 × 10-3 kg/(person·a) and the eutrophication was 1.7 × 10-3 kg/(person·a).
