摘要/Abstract

摘要： 水化学迁移率是反映污染质在水-土孔隙介质中迁移锋面速度的参数，参数值的大小与土壤介质性质、水流状态、污染物质的物理化学性质有关。利用淋滤土柱的动态平衡试验法，模拟自然降雨入渗条件下，石油类污染物在吉林油田区包气带土层中的迁移转化过程。试验结果表明，其水化学迁移过程可分为淋溶阶段、吸附阶段和平衡阶段;微生物分解作用比较弱；不同厚度土层的淋滤液浓度衰减曲线趋势极为相似。考虑室内实验与野外自然环境之间存在的尺度效应，合理确定了阻滞因子、水化学迁移率。

Abstract: Hydrochemical mobility is a parameter reflecting the velocity of the transference front sharp of pollutants in watersoil pore medium, which relates to the soil property, water flow state and physicochemical property of pollutants. The dynamic balance of the soil pillar leaching experiment is used in this article to simulate the transference and transformation of the oil pollutants in the aeration zone of Jilin oilfield under the conditions of natural rainfall infiltration. The results show that the hydrochemical transference can be divided into leaching stage, adsorption stage and equilibration stage. The microbe decomposition is very weak. The concentration attenuation curves of leaching liquid in differentthickness soil layers are quite similar. The scale effect has been considered between indoor experiments and natural environment to determine the retardation factor and the hydrochemical mobility properly.

Key words: oil pollutant, soil layer in aeration zone, hydrochemical mobility, scale effect
