摘　　要：对上海城市生活垃圾的组成、燃烧特性、元素分析及热值等试验结果的分析表明：粒径为40～120mm的垃圾含量最大，试验的平均质量分数约为43．5％；其次是粒径为8～40mm的垃圾，平均质量分数约为34．9％；粒径大于120mm的约为15．7％，小于8mm的约为5．8％．有机物质量分数高，约占65％，且含水率高，热值低，不适合焚烧；可燃物（塑料、纸类、纺织物、包装物、木块）质量分数约为30％，含水率较低，热值高，适合焚烧．由此说明，上海城市生活垃圾的处理不宜采用单一的方式，必须综合处理以利于垃圾资源化．An analysis is made of the composition, combustion characteristic and caloric value of municipal solid waste （MSW） in Shanghai. The experiment results show that, in MSW of Shanghai, the percent of refuse with size range from 40 to 120 mm, size range from 8 to 40 mm, size 〉120 mm and size 〈8 mm is 43.5%, 34.9%, 15.7% and 5.8%, respectively. Of the 12 kinds of matter in Shanghai MSW, the organics is about 65% and combustible （plastics, papers, textile, packing, block） about 30%. Organics is unsuitable for incineration treatment because of higher moisture and lower caloric value. The combustible is suitable for incineration treatment because of lower moisture and higher caloric value. Comprehensive treatment for Shanghai MSW is proposed.
