中文摘要：

利用ISO＂生命周期评价原则与框架＂,提出了混合建模（PELCA）的生命周期分析方法,对城市垃圾厌氧发酵车用沼气燃料进行了生命周期能耗和环境排放分析,并对安阳市垃圾厌氧发酵车用沼气燃料进行了生命周期评价.结果表明：城市垃圾厌氧发酵的沼气完全满足国标对车用压缩天然气（CNG）燃料的要求.在城市垃圾厌氧发酵车用沼气燃料生命周期中,全球变暖对环境影响负荷贡献最大,气溶胶最小.车用沼气燃料生命周期环境影响负荷中,车辆运行阶段产生的环境影响最大,燃料阶段最小.城市垃圾厌氧发酵可以作为城市决策者处理垃圾方式的参考依据.

英文摘要：

By using ISO ＂life cycle assessment principles and framework＂, energy consumption and en- vironmental emissions of vehicle biogas life cycle for anaerobic fermentation of municipal waste are ana- lyzed. Life cycle analysis method based on PELCA （Hybrid Life Cycle Assessment）hybrid modeling is proposed, and vehicle biogas for anaerobic fermentation of municipal waste in Anyang city is evaluated with life cycle assessment. The results show that the biogas fully meets the requirements of vehicle CNG （Compressed Natural Gas）. In life cycle assessment of vehicle biogas, global warming is the largest contribution to the environmental impact load, and aerosol is the smallest. In environmental impact load of vehicle biogas fuel life cycle, the largest contribution to the environmental impact load is in vehicle operation phase, and the least is in fuel stage. The waste disposal methods for anaerobic fer- mentation of municipal waste could be used as reference information for urban policymakers.
