【摘要】 目前,重庆市主城区生活垃圾以填埋方式为主,二次污染严重,采用"三化"方式处理生活垃圾势在必行。通过对主城区垃圾不同地点进行的生活垃圾取样,分析了垃圾的理化性质。实验结果表明:重庆市主城区生活垃圾组分以厨余垃圾为主,易燃烧的塑料、纸张含量较低;含水率高,可燃分和灰分较低,垃圾的热值基本满足燃烧要求;垃圾元素中C、H、O含量较高,并含有一定N、S和Cl。高含量的厨余垃圾,是影响垃圾焚烧质量的主要因素。若采取有效的措施,提高垃圾的热值,可采用焚烧方式处理部分生活垃圾。更多还原

【Abstract】 Currently, municipal solid waste(MSW) is mainly disposed by landfill in the urban zone of Chongqing. Because this disposal results in serious secondary pollution, it is imperative to be dispose of by the way of reduction, resource and harmlessness. The MSW is sampled in different places, and characteristics are investigated. The experimental result indicates that in the urban zone of Chongqing the garbage is mainly composed of MSW, the calorific value of MSW is suitable for incineration in despite its high water content, low combustibility and ash content. The content of C, H and O is high and the solid waste contains a few N, S and Cl. The high content of garbage is influencing factor for incineration. If some effective measures are taken to increase the calorific value of MSW, part of the MSW can disposed by incinerating.更多还原
