| 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,考察了填埋垃圾组成随填埋年份的变化规律.分选结果表明:在缺氧和避光的封场环境中,填埋垃圾中塑料、橡胶和化纤织物组分在未发生明显老化,经简单预处理后即可再生利用;以塑料为主的有机组分随填埋年份呈对数上升趋势,2010年将占填埋垃圾的50%以上.因此,焚烧和气化热处理工艺将是填埋垃圾资源化的理想选择之一.

| Abstract: | Refuse at Shanghai refuse landfill was excavated from the compartments closed from 1991 to 2004; and the composition of aged refuse was studied. The results show that plastic and rubber fractions were well preserved from photodegradation and oxygen aging in closed compartments, and can be recycled after simple pretreatment; the content of organic fraction, mainly including plastic fraction, increased logarithmically with placement time and will exceed inorganic fraction after 2010. Thus thermal treatment, such as incineration and hydrolysis, may be effective ways for the cycling of aged refuse. |
