| 摘 要： | 城市生活垃圾的工程性质对填埋场设计、建设及管理有一定的影响.为研究城市生活垃圾的粒径大小及组成情况,运用120mm、80mm、40mm和8mm孔径的手动筛对城市生活垃圾进行筛分实验,实验结果表明：城市生活垃圾在80mm筛上的筛余量最多,在40mm筛上的生活垃圾种类较多,组成较为复杂.城市生活垃圾的细度模数为2.71,不均匀系数和曲率系数分别为0.45和1.36,表明城市生活垃圾的级配不良.为实现生活垃圾的分类,建议根据不同粒径采用不同的分选技术.

| Abstract: | The engineering character of household garbage in cities has an impact on the design,the construction and the management of landfill sites.By using 4 screens with apertures 120mm,80mm,40mm and 8mm respectively,the screening experiment is carried out in order to find out the grain size and substance variety of the household waste.The result shows that the weight of screen residue on the screen of 80mm is most and the variety on the screen of 40mm is complex.The fineness modulus is 2.71,and the asymmetry and ... |
