摘    要:通过Batch法研究了土壤吸附苯胺的动力学特征;通过土柱试验模拟了苯胺在土壤中的扩散,同样通过土柱试验研究了两种应急处置方法。试验结果表明,土壤吸附苯胺的反应呈现快速反应和慢速反应两个阶段,以快速吸附反应为主;苯胺在土壤中的扩散浓度与扩散深度的关系可用指数方程表征。通过动力学吸附试验和苯胺在土壤中的迁移试验的结果,确定了挖掘距表面层50ram的污染土壤和在污染表面撒粉末活性炭吸附两种有效的应急处置方法。

关 键 词:苯胺污染  土壤  应急处置  模拟  实验  研究

Abstract:The dynamics of soil adsorption characteristics of aniline has been studied by Batch method. In the col- umn tests, the diffusion of aniline in the soils was simulated and the two emergency treatment methods were studied as well. The results show that the adsorption of aniline experienced two stages, that is, fast adsorption and slow ad- sorption, but mainly the former. The concentration and depth of the aniline migrating in the soils could be ex- pressed by an exponential equation. The experiments of adsorption dynamics and migration show that there are two efficient emergency treatment methods, that is, digging up the 50mm - thick layer of the contaminated soil below the surface and spraying the powder of the activated carbon on the contaminated surface.
Keywords:aniline pollution  soil  emergency treatment  simulation  experiment  study
