摘要
通过室内土柱实验研究了锶在不同润湿性介质中的迁移规律和特征,并采用CXTFIT 2.1软件对实验结果进行了拟合,通过实验数据计算了延迟因子。结果表明:在疏水介质中,锶的穿透速度较快,利用平衡CDE方程或两区模型来模拟锶在三种润湿性不同的石英砂柱中的迁移均是可行的,但两区模型的模拟效果更好。
The transport laws and features of strontium in media with different surface wettability were proceeded by column experiments.The experimental results were fitted by CXTFIT2.1 software,and retard factor was also calculated.The results have shown that the penetrating velocity of strontium was higher in hydrophobic media.Both the equilibrium CDE model and the two-region model could fit the experimental data of Br in sand media with different wettability well,and the two-region model is better for the fitting of strontium in the surface-modified sand column.
