摘　　要：将土壤污染物分为非卤代VOCs、卤代VOCs、非卤代SVOCs、无机物等8大类型,并在分析污染土壤原位修复和异位修复两种方式不同特点的基础上,根据各种修复技术的不同作用原理,较为全面地介绍了目前国内外各种物理/化学修复的技术原理、适用性、局限性、实施时间及处理成本等,具体包括化学淋洗、蒸汽抽提、强化破裂、空气喷射、可渗透反应墙、固化/稳定化、电动学、物理分离、热解吸、玻璃化等修复技术。针对几种常见的土壤污染类型,列举了一些可行的组合修复工艺。Soil contaminants are classified into 8 groups here, such as nomhalonated volatile organic carbons （VOCs）, halonated volatile organic carbons （VOCs）, non-halonated semi volatile organic carbons （SVOCs）, inorganlcs, etc. After presenting the advantages and disadvantages of both in-situ and ex-situ remediations, the mechanism, applicability and limitations of various treatment technologies of physical/chemical remediation are discussed in considerable details. Technologies such as soil washing, soil vapor extraction, permeable reactive wall, stabilization/ solidification, thermal desorption, vitrification, etc. are all included here. A number of treatment trains are listed for some common contamination sites.
