摘要:随着人类社会的不断向前发展,人们对生活和工作环境的要求逐步提高,近年来,国内城市生活垃圾产量日益剧增,根据我国生活生活垃圾的构成情况,以国内部分城市生活垃圾的燃烧处理为研究对象,结果表明,垃圾构成发生了很大变化,由于其中有机物、可燃物和可回收利用成分增加;垃圾热值也相应提高,部分城市生活垃圾的热值达到5000kJ/kg左右,而垃圾燃烧产生的高温烟气可作为热能回收利用,性能稳定的残渣可直接填埋或做建材用。

Abstract: with the continuous development of human society forward, people to the life and the work environment requirements gradually improve, in recent years, the domestic city life garbage output increasingly excursion, according to our country life garbage structure situation, with the domestic part of city life garbage burning treatment as the research object, and the results show that, the position changed, because anic matter, fuel and may be recycled ingredients increase; Waste calorific value also increase, part of city life garbage calorific value reached 5000 kj/kg or so, and garbage from the burning of high temperature flue gas can be used as heat energy recycling, performance and stability of residue can be directly landfill or do with building materials.
Keywords: city life garbage; position; Combustion; Calorific value.
0引言
为了能够经济的利用垃圾资源,实现垃圾的变废为宝,为社会提供可利用资源。从20世纪50年代的城市垃圾污染严重的时期到60年代中期,已经大体形成了填埋、焚化、堆肥等一系列处理方法。根据垃圾产生源不同,可将我国城市垃圾主要分为居民生活垃圾、街道保洁垃圾和集团(机关、学校、工厂和服务业)垃圾三大类。研究表明,我国城市生活垃圾的有机物含量近年呈逐年增加的
