| 摘 要： | 我国生活垃圾分类运输能耗高的问题一直未能根本解决。对该环节开展能耗分析是综合评价垃圾分类环境、经济效益的基础，也可为我国城市垃圾分类运输系统设计提供依据。基于分类垃圾性质与产生特征，结合运输车辆运行规律，构建了以居民区、办公区/商业区及学校为主要业态的3类典型城市区域分类垃圾直接运输，以及一级转运运输场景，并对各场景综合能耗进行核算。结果表明:不同典型城市区域生活垃圾分类运输单位能耗差异不显著直运0.11~0.12 kgce/（t·km），转运0.06~0.08 kgce/（t·km）]，分类运输较混合运输能耗增加77%~116%（直运）和25%~42%（一级转运），而转运操作对运输能耗的降低与运输距离负相关。对各垃圾组分而言，厨余垃圾运输能耗直运0.09~0.10 kgce/（t·km），转运0.05~0.07 kgce/（t·km）]略低于其他垃圾和可回收物直运0.11~0.13 kgce/（t·km），转运0.07~0.08 kgce/（t·km）]，而有害垃圾运输能耗最高直运0.21~0.30 kgce/（t·km），转运0.13~0.20 kgce/（t·km）]。

| Abstract: | Although lots of energy was consumed in municipal solid waste (MSW) classification transportation, little researches were focused on this process. The energy consumption analysis is not only the basis of the comprehensive evaluation of the environment and economic benefits of MSW classification, but also the basis for the designing of MSW classification and transportation systems. In this study, three typical scenarios (residential area, office/business area, and school area) of MSW classified transportation were developed and the energy consumption in each scenario was calculated. The results showed that:there was no significant difference in energy consumption in these three MSW classified transportation scenarios. Compared with the mixed MSW transportation, the energy consumption of classified transportation increased by 77%~116% (direct transportation) and 25%~42% (single stage transshipment), and the reduction of transportation energy consumption caused by transshipment was negatively related to the transportation distance. For each waste component, the energy consumption ascending order in transportation was food waste0.09~0.10 kgce/(t·km) by direct transportation, 0.05~0.07 kgce/(t·km) by transshipment], residual waste or recyclables0.11~0.13 kgce/(t·km) by direct transportation, 0.07~0.08 kgce/(t·km) by transshipment], and hazardous waste0.21~0.30 kgce/(t·km) by direct transportation, 0.13~0.20 kgce/(t·km) by transshipment]. |
