摘　　要：为了探究上海城市生活垃圾资源化模式，试验采用方孔径为120、40、8mm的3种手动筛，对垃圾进行筛分，并对筛分后不同粒径的垃圾进行了分类．结果表明：粒径为40～120mm的垃圾含量最大，试验的平均百分比约为43.5％；其次是粒径为8～40mm的垃圾，平均百分比约为34．9％；粒径〉120mm的约为15．7％；粒径〈8mm的约占5．8％．随着粒径的变小，可生物降解有机物含量增加，塑料含量降低．12类垃圾中，可堆肥的有机垃圾约占65％；可焚烧垃圾（塑料、纸类、纺织物、包装物、木块和部分余下物），约占30％；可回收二次利用的垃圾（玻璃、铁金属和非铁金属），约占2．5％；有毒有害垃圾约占0．39％；剩余的无机垃圾量不足3％．试马命结果表明，此方式为上海提供了一个牛活垃圾集中分选资源化模式．In order to explore municipal solid waste（MSW）resource reuse mode in Shanghai, the MSW was screened by 3 kinds of handing screens with square apertures 120mm, 40mm and 8mm respectively. The different sizes of MSW was sorted into organics, plastics, paper, textile, packing, glass, iron, nonferrous metal, blocks, minerals, poisonous and harmful refuse and so on. The results of experiments indicated that, in MSW of Shanghai, the percentages of refuse with size ranges from 40 to 120 mm, size ranges from 8 to 40 mm, sizes 120 mm and sizes 〈8 mm are 43.5%, 34. 9%, 15.7% and 5.8% respectively. In the 12 kinds of matter in Shanghai MSW, refuse for compost （organics） is 65%; refuse for conflagration （plastics, paper, textile, packing, block） 30%, refuse for reuse （glass, iron, nonferrous metal） 2.5%; poisonous and harmful refuse 0. 39%. According to the above-mentioned test results, MSW centralized separation and resource reuse mode suitable for Shanghai was suggested. It will provide basis for the further development of reuse of MSW in Shanghai in the near future.
