四川省城市生活垃圾的组成及特性

Characteristic and Composition of Municipal Solid Waste in Sichuan Province

对四川省典型城市生活垃圾的组成、元素分析及热值等实验结果进行分析,结果表明:典型城市生活垃圾具有厨余含量高(57.4%～66.1%)、渣土含量少(1.9%～11.7%)的特点;四川省城市生活垃圾热值介于4 200～5 500 kJ/kg之间,且大部分处在4 800～5 500 kJ/kg之间;攀枝花、绵阳和成都市金牛区城市生活垃圾热值较高,适合采用焚烧法,内江和遂宁的城市生活垃圾热值偏低,宜采用填埋的方法。

An analysis is made of the composition ,elemental analyses and caloric value of municipal solid waste（MSW） of typical cities in Sichuan province. The results show that the food waste content of MSW in Sichuan province between 57.4% -66. 1% , and debris content between 1.9%-11.7% ;The caloric value of MSW between 4 200-5 500 kJ/kg, and the majority of them is between 4 800-5 500 kJ/kg. MSW of Panzhihua, Mianyang, Jinniu district which have relatively high caloric value are more proper disposed by incineration; MSW of Neijiang, Suining which have relatively low caloric value are more proper disposed by landfill.
