摘　　要：重金属和多环芳烃(PAHs)常共存于土壤中形成复合污染。作为典型无机污染物和有机污染物的代表,淋洗法可同时有效去除这两类污染物,具有良好的发展前景。本文结合国内外的研究成果,从重金属和 PAHs 在环境中的行为着手,重点论述了常用淋洗剂的种类、去除机理和优缺点,分析了影响复合污染物去除效果的主要因素,并对今后该技术的发展方向进行了展望。As representatives of typical inorganic and organic pollutants, heavy metals and polycyclic aromatic hydrocarbons （PAHs） are coexisted regularly in soil. Leaching is considered as the most efficient and promising process in the remediation of the soil contaminated by these two types of pollutants. The domestic and foreign research results, and the behaviors of heavy metals and PAHs is the environment are introduced, and the commonly used agents, relevant action mechanisms, advantages and disadvantages, major factors affecting removal efficiency of leaching process are discussed in detail. The future development of leaching process is prospected.
