垃圾填埋场腾发覆盖研究进展

Research Progress of Landfill Evapotranspiration Cover

目前国外最新的渗沥液控制理念是通过覆盖层土壤蒸发和植物蒸腾来调节降水入渗,最大限度地降低渗沥液排放量,达到控制污染的效果.综述国内外有关腾发覆盖理论的研究现状,对其入渗作用机理、水量平衡模型、数值模型以及研究方法等方面的最新研究成果进行分析,提出了未来腾发覆盖理论研究的方向和重点,为该项技术的发展与应用提供参考.

The latest foreign leachate control philosophy is to regulate the infiltration of precipitation by overburden soil evaporation and plant transpiration （ET Cover）, so that leachate emissions can be minimized to achieve the goal of pollution control. The domestic and foreign research on evapotranspiration cover theory is summarized; the water balance model, numerical models and research methods are analyzed, and theoretical research direction and focus of evapotranspiration cover in the future are proposed.
