【摘要】 采用孔径为120 mm,40 mm和8 mm的三种手动筛,对生活垃圾筛分,并对筛分后生活垃圾分类.通过对其质量和含量的测定,得出如下结论:粒径大于120 mm范围内的生活垃圾中,有资源化潜力的组分为塑料、有机物、纸类、包装物及玻璃;粒径为40~120 mm范围内生活垃圾中,有资源化潜力的组分为有机物、塑料、玻璃、金属和包装物;粒径为8~40 mm范围内的生活垃圾,只要将玻璃分离开来,可以直接生物处理;而粒径小于8 mm的生活垃圾,可以直接生物处理.根据这个实验结果,为上海市生活垃圾制定了一条机械分选流程.更多还原

【Abstract】 The typical municipal solid wastes generated in Shanghai were sorted into three components using screeners with pore sizes of 120 mm,40 mm and 8 mm,and then classified further for each component.For the components over 120 mm in size,the recyclables are observed to be plastic,compostable organic matters,paper,packaging materials and glass.For the components with 40-120 mm in size,the recyclables include compostable organic matters,plastic,glass,metals,and packaging materials,while the components with 8-40 mm in size mainly comprise of compostable organic matters with little glass,The compostable organic matters predominate in the fractions below 8 mm in size and can be composted directly.The findings thus obtained are used for the design of mechanical separation of municipal solid wastes in Shanghai and some other cities in China.更多还原
