摘要
在今后较长一段时期内,我国城市生活垃圾的处置仍将以填埋法为主。面对新建填埋场的困难日益增加,对现有填埋场的矿化垃圾进行开采和资源化利用,可有效地扩大填埋容量,延长填埋场使用年限。开采出的矿化垃圾,可从中回收大量废旧有用物资,可用作填埋场日覆盖材料、种植和绿化用营养土,可加工成建筑材料,可用作生物反应床填料有效地处理渗滤液、生活污水、禽畜废水、难降解废水和废气。本文介绍了矿化垃圾的定义、性质、开采和综合利用的途径,总结了相关研究和应用进展。
Sanitary landfill has been and still will be the main method of the municipal solid wastes both nowadays and in a long period of future in China. Since the construction of new landfills is becoming more and more difficult, it is feasible to excavate and utilize the aged refuse in landfills, which can greatly enlarge the landfill capacity and extend the service longevity of the landfill. Considerable useful materials can be reclaimed from the aged refuse. The excavated aged refuse can be used as daily cover material, the nutrimental soil, processed construction material, and the packing material for biofilters to effectively treat various waste waters such as landfill leachate, sewerage, livestock and poultry waste water, refractory waste water, and waste gases. This paper discusses the concept, properties, excavation and comprehensive utilization of the aged refuse, reviewing the progress in relevant study and applications.
