摘　　要：近年来,污染地块的原位加热处理技术(ISTT)因其修复效率高、修复周期短、适用范围广以及可以达到极低的修复目标等优点得到快速发展及广泛应用。原位加热强化与土壤气相抽提(SVE)、地下水抽出-处理(P&T)以及微生物修复等技术的联合应用为含非水相液体(NAPLs)、均质化较差以及渗透性低的污染地块快速修复提供了可能。然而,国内原位加热处理技术的研究及应用仍处于起步阶段,急需系统的基础研究及应用研究。本文系统介绍了4类常用原位加热技术,综述国内外污染地块原位加热处理技术的研究现状,并结合我国污染地块的特点探讨国内污染地块原位加热处理技术研究开发需求。指出国内应同等重视原位加热技术及抽出蒸汽和液体处理技术的研究,开发高效、廉价、快速、便捷以及环境友好的原位加热处理技术及配套的集成化、模块化及智能化修复设备。In recent years,in-situ thermal treatment(ISTT)for contaminated site remediation has beendeveloped rapidly and applied widely because of its high remedial efficiency,short period ofremediation time,wide application scope and very low remediation targets.Usually,in-situ thermaltechnologies are used in conjunction with soil vapor extraction(SVE),pump and treatment(P&T)andbiodegradation.These combined technologies are available for addressing recalcitrant contaminatedsites,which are source zones with non-aqueous phase liquids(NAPLs)heterogeneity and lowpermeability.However,the research and application of ISTT technologies are still at the initial stageand it is an urgent need for systematically basic and applied research in China.This paper focuses onintroduction to four frequently used thermal technologies and reviews the current research status ofISTT domestically and internationally.Besides,it is also discussed demands for research anddevelopment of ISTT in China based on the features of Chinese contaminated sites.It is concluded thatequal attention needs to be paid to the research of in-situ thermal technologies and treatmenttechnologies for vapor/liquid extraction.China should develop efficient,low-cost,rapid,convenientand environmentally friendly in-situ thermal treatment technologies and supporting equipment with integrated,modular and intelligent features.
