Abstract One of the most important problems concerning contaminant transport in the ground is the problem related to the definition of parameters characterizing the adsorption capacity of ground for the chosen contaminants relocating with groundwater. In this paper, for chloride and sulfate indicators relocating in sandy ground, the numerical values of retardation factors (Ra) (treated as average values) and pore groundwater velocities with adsorption (ux/Ra) (in micro-pore ground spaces) are taken into consideration. Based on 2D transport equation the maximal dimensionless concentration values (C*max c) in the chosen ground cross-sections were calculated. All the presented numerical calculations are related to the unpublished measurement series which was marked in this paper as: October 1982. For this measurement series the calculated concentration values are compared to the measured concentration ones (C*max m) given recently to the author of this paper. In final part of this paper the parameters characterizing adsorption capacity (Ra, ux/Ra) are also compared to the same parameters calculated for the two earlier measurement series. Such comparison also allowed for the estimation of a gradual in time depletion of adsorption capacity for the chosen sandy ground.

所选沙地对随地下水迁移的污染物的吸附能力

摘要 关于污染物在地下迁移的最重要问题之一是与表征地面对随地下水迁移的选定污染物的吸附能力的参数定义相关的问题。本文对砂质地基中迁移的氯化物和硫酸盐指示剂，取阻滞因子(Ra)(取平均值)和吸附孔隙地下水流速(ux/Ra)(在微孔隙地面空间中)的数值考虑在内。基于二维传输方程，计算了所选地面横截面中的最大无量纲浓度值 (C*max c)。所有提出的数值计算都与未发表的测量系列有关，在本文中标记为：1982 年 10 月。对于该测量系列，将计算出的浓度值与最近提供给本文作者的测量浓度值 (C*max m) 进行比较。在本文的最后部分，表征吸附容量的参数 (Ra、ux/Ra) 也与为两个较早的测量系列计算的相同参数进行了比较。这种比较还允许估计所选沙地的吸附能力随时间逐渐耗尽。
