摘要
为推动资源回收后的再度利用并提升资源利用效率,以某地区年处理量为5万t的分拣中心为研究对象,开展“一袋式”回收试验,对可回收物的种类和比例进行分类与分析,并构建计算模型,对其经济性和环境影响进行综合评估,探讨城市生活垃圾分类回收的可行性和效益。结果显示,城市垃圾分类回收能够明显减少大气污染物的排放,特别是颗粒物(PM)、二氧化硫(SO_(2))、氮氧化物(NO_(X))、氯化氢(HCl)、二氧化碳(CO_(2))和二噁英(dioxin)的排放。垃圾分类回收有助于环境保护,能够通过资源再利用提高资源利用效率。
To promote the reuse of recycled resources and improve the efficiency of resource utilization,taking a sorting center with an annual processing capacity of 50,000 tons in a certain area as the research object,a'one-bag'recycling experiment was carried out.The types and proportions of recyclables were classified and analyzed,and a calculation model was constructed to conduct a comprehensive assessment of their economy and environmental impact.To explore the feasibility and benefits of urban domestic waste classification and recycling.The results show that urban waste classification and recycling can significantly reduce the emissions of air pollutants,especially particulate matter(PM),sulfur dioxide(SO_(2)),nitrogen oxides(NO_(X)),hydrogen chloride(HCl),carbon dioxide(CO_(2)),and dioxin.Garbage classification and recycling contribute to environmental protection and can enhance the efficiency of resource utilization through resource reuse.
