| 摘 要： | 对我国309个地级城市的蒸发量和降水量数据进行了收集和分析,得出不同区域蒸降比的分布规律,并据此得出不同蒸降比条件下各地区垃圾填埋场渗滤液处理工艺选择的基本思路。即:蒸降比>2.0时,推荐采用渗滤液循环回灌处理工艺而实现渗滤液不外排或减少外排量;当蒸降比为1.5～2.0时,可采用回灌与其他技术相结合的处理工艺;当蒸降比<1.5时,不推荐采用回灌技术。如此以期达到降低我国渗滤液管理和处理难度,节约投资和运行成本的目的。

| Abstract: | The evaporation and precipitation data in 309 prefecture-level cities in China were collected and analyzed,and the distribution regularities of evaporation-precipitation ratios in different regions were obtained.Based on the summarized results,the basic idea of process selection for leachate treatment in municipal solid waste landfill sites in regions with different evaporation-precipitation ratios was proposed.When the evaporation-precipitation ratio is more than 2.0,leachate recirculation is recommended t... |
