摘要
以漠大线沿线地区的泥炭质黏土和风化砂混粉质黏土为研究对象,采用箱体动态模拟法和球体积预测模型,研究了林源俄油在土壤中的迁移规律。结果表明:在组分纷杂的土壤体系中,原油在垂直向上方向迁移速率最小,在其他方向的迁移规律不明显。采用振荡平衡法,探讨了2种土壤对原油的吸附性能。结果表明:2种土壤吸附原油的过程遵循Lagergren二级动力学方程,土壤吸附原油的平衡吸附量大小关系为:泥炭质黏土>风化砂混粉质黏土。
Migration patterns of crude oil in the peat clay and the sand mixed silty clay along the China-Russia oil pipeline were determined by using the integral sphere model and the box body dynamic simulation method. The results showed that migration velocity of crude oil in the vertical upward direction was the minimum while migration regularity was not obvious in the others direction. The equilibrium method had been applied to discuss the performance of two kinds of soil adsorption on crude oil. The adsorption processes of crude oil in two soil samples were both consistent with the pseudo second order type adsorption kinetics.The equilibrium adsorption quantity of the crude oil in soil decreased in the following order： peat clay sand mixed silty clay.
