摘要
近几年来,随着工农业生产的巨大发展和人口的急剧膨胀,垃圾的产生量越来越多。我国垃圾平均增长率达9%以上,超过世界平均增长率(8.42%)。因此垃圾处理是个亟待解决的问题。目前处理城市垃圾固体废弃物的常用方法是填埋法,而垃圾的堆放对周围的环境造成了影响,尤其是对水环境影响更大。很多堆放场产生的垃圾渗滤液严重地污染了地下水质。作者从微生物的角度、土水势的角度和水在多孔介质中渗流的角度,提出了处理垃圾填埋场渗滤液的方法。
In the last few years, with the great development of Industry and agriculture and rapid expansion of population, garbage has produced more and more, In our country, the average rate of garbage increase reaches more than 9%, which exceeds world average rate （8.42%）. Correspondingly, garbage disposal is a problem needing to be handled immediately. In most cities of China, garbage is disposes by means of landfill. However, the heap of garbage has done harm to the surrounding environment, especially the water environment, Many landfills have produced leathate, which severely polluted the quality of underground water. The auther of this paper proposes leachate disposal measurements of landfill from the microbial perspective, soil-water potential perspective and water＇s flowing in porous media perspective, deserving the attention from engineering.
