摘　　要：表面活性剂冲洗法是一种治理土壤与地下水非水相流体(NAPLs)污染的有效技术。在简要介绍表面活性剂冲洗法去除作用机理的基础上,总结了近些年来与表面活性剂冲洗法多相流相关的国内外试验研究和模型研究成果,主要包括表面活性剂作用所引起的混溶驱替和不混溶驱替多相流问题,并指出目前研究中存在的问题和进一步探讨的方向。Surfactant flushing has been proposed as an effective method for the treatment of soil and groundwater polluted by nonqueous phase liquids （NAPLs）. In this paper, removal mechanisms of soil flushing with surfactant are presented in brief; then advances and achievements of experimental study and model simulation on muhiphase flow related to NAPLs recovery by soil flushing both in China and abroad are introduced and reviewed, chiefly including miscible displacement and immiscible displacement in the case of surfactant. At the same time, some problems existing in current study and issues needed to be further approached are presented.
