摘要
为更好践行和实施北京市垃圾分类要求,选取北京市典型单位和典型地区的垃圾进行采样,分析不同功能区生活垃圾物理组成及特征差异。聚类分析结果表明:典型单位中的地铁站、大型超市、办公区、文教区、体育馆以及典型地区中的商业区、事业文教区和道路的生活垃圾聚类为两类,特点为可回收垃圾含量较多,可大类粗分为可回收垃圾和不可回收垃圾;典型单位的居民区、旅游景点、广场、饭店以及典型地区的农村、平房区、高档住宅区、双气区、旅游区和广场区的生活垃圾聚类为3类,特点是厨余垃圾含量较多,可大类粗分为厨余垃圾、可回收垃圾以及其他垃圾。因此,将厨余垃圾与可回收垃圾进行有效利用,可最大程度上实现生活垃圾的减量化和资源化。
In order to better practice and implement Beijing municipal waste classification requirements,waste samples from typical institutions and areas in Beijing were selected,in order to analyze the physical composition and characteristics difference of MSW in different functional areas.The results of cluster analysis showed that the MSW from subway station,hypermarket,office area,culture and education area and gymnasium in typical units,and the MSW from business district,business culture and education areas as well as roads in typical areas clustered in two types,characterized by more recyclable waste content,which could be approximately classified into recyclable and non-recyclable waste.The residential areas,tourist attractions,squares,hotels in typical units and rural areas,cottage areas,high-end residential areas,gas and heating areas,tourist areas and square areas in typical areas clustered in three types,characterized by a large amount of kitchen waste,which could be roughly divided into kitchen waste,recyclable waste and other waste.Therefore,the effective utilization of kitchen waste and recyclable waste could achieve the reduction and recycling of MSW to the greatest extent.
