摘要
针对我国某地乙烯厂含油污水渗漏污染含微裂隙土层并致使地下水源受到油类污染的实际情况，在对土层物理性质和水力学性质研究的基础上，进行了原状土柱含油污水淋滤试验。研究证实了土层残油对地下水源污染的严重性和长久性。并在我国首次选择水力冲洗和表活剂冲洗两种技术对土层残油的去除效果进行初步研究，结果表明了表活剂水溶液冲洗效果优于水力冲洗的效果。
Undisturbed experiments on soil physical and hydrodynamic characteristics were conducted on micro-fractured clay soil on site of an ethylene work in China. The results confirm the serious and permanent groundwater pollution by soil residual oil. Two techologies of waterwashing and surfactant-washing were chosen to remove the residual oil in the soil, and the results indicate that the removal efficiency of surfactant (AES) solution is better than that of clean water.The ion-remidiation emchanics of water-washing and surfactant-washing from clay soil was clarified.
