| 摘 要： | 用若干土柱模拟试验研究了垃圾渗滤液有机污染组分在不同岩性、不同厚度包气带介质中的运移规律,并计算了有机污染组分在包气带中运移的有关水化学迁移参数(阻滞因子R和水化学迁移率E).结果表明,有机污染组分在不同岩性介质中的R值顺序为:粘土＞亚粘土＞砂土,在相同岩性中随着厚度的增加R呈正相关增大.从而为评价和预测垃圾场对地质环境影响提供技术参数,并为垃圾场的选址提供理论依据.

| Abstract: | The transport law of leachate pollutant COD in different lithology and thickness vadose zones was studied , and some concerned hydrochemical transport parameters(retardation factor R and the rate of hydrochemical transport E)of COD in vadose zones was also calculated. The results showed that R of COD in different lithology is from higher to lower in the sequence of clay, subclay, and sand soil; and that R is increased by positive correlation with the increase of thickness in the same lithology. These provided technological parameters for evaluating and forecasting the geological environmental effects of landfills, and also provided theoretic basis for selecting addresses of landfills. |
