石油类污染物在充填状灰岩裂隙中迁移规律研究

针对淄博市大武水源地的石油污染状况进行了动态模拟石油类污染物迁移特性的研究。内容包括用现场粘土充填灰岩石板缝测定弥散系数、吸附系数及其他有关参数，建立该系统在饱水条件下的迁移数学模型。研究表明静态吸附均遵循Ｌａｎｇｍｕｉｒ吸附模式，且吸附能力较小；静态吸附结果与动态参数比较吻合，可直接用于建立整体模型；水中的石油类污染物在地表以下迁移性很强，容易下渗进入潜水层。

Study on transport pattern of oil contaminants in the filled crevices of limestone

In accordance with the situation of oil pollution in Dawu water source district,Zibo City,a dynamically simulating study on transport performance of oil con-taminants has carried out. The study includes measuring diffusion coefficient,adsorption coefficient and another parameters of limestone crevice filled by spot clay and developing the mathematical diffusion model of this svstem under the condition of saturated with water. The study resuIts show that:the static adsorption with a small adsorption capaci-ty obeys the Langmuir adsorption model;measurements of the static adsorption fit with the dynamic parameters and can be directly used to establish comprehensive model;and oil contaminants in water have stronge transportability in underground and can permeate into groundwater with ease.
