| 摘 要： | 在上海老港生活垃圾填埋场，对1991-2004年间填埋垃圾进行了小规模开采和手工分选，考察了填埋垃圾的组成随填埋年份的变化规律，对填埋垃圾的资源化价值进行了初步评价．分选结果表明：矿化垃圾中可资源化组分主要为生物活性渣土和塑料，14年平均含量分别为50．2％和25.5％．填埋垃圾组成随填埋年份呈明显的对数变化，生物活性渣土含量逐年下降，塑料含量则保持不断上升趋势、这说明矿化垃圾具有较高的资源化价值，是一种有待开采利用的资源、

| Abstract: | Refuse at Shanghai Refuse Landfill was excavated from the compartments closed from 1991 to 2004 and its recoverables were separated and weighted. The relationship between the quantity of various recoverables and its placement time was studied. The results show that the fines fractions with 4 cm in size and plastic account for around 50.2 % and 25.5 % in the excavated refuse respectively. A logarithmic relationship is established between placement and fraction contents. The contents of plastic increase with placement time while those of finer ad refuse decrease. It is predicted that plastic would be the main fraction in the refuse placed after 2007. The aged refuse is considered to be a recyclable resource. |
