摘　　要：当前,我国城市化不断发展,许多近郊的工业企业都进行了搬迁或停产,遗留了大量受污染的土地。目前国内外应用于污染场地修复的技术较多,采用科学方法选取经济、高效、技术可行的修复技术尤为重要。以苏南某市某有机污染地块为例,采用TOPSIS法根据污染物特征、修复目标及污染地块现状等因素,结合以往类似修复工程的经验进行评估,确定最优修复方案。研究结果表明,低温解吸与最佳修复技术相对接近度最高。对轻度污染土壤,推荐采用原地异位化学氧化技术;对重度污染土壤,采用低温解吸改良预处理后再进行热脱附处理。该研究不仅为地块后续修复管理工作提供了依据,同时也可作为工程案例,为相同类型的污染地块修复方案的制定提供参考。At present,with the continuous development of urbanization in China,many industrial enterprises in the suburbs have been relocated or stopped production,leaving a lot of polluted land.At present,there are many technologies applied to the remediation of polluted sites both domestically and internationally.It is particularly important to use scientific methods to select economical,efficient,and technically feasible remediation technologies.Taking an organic polluted land in southern Jiangsu Province as the research object,the TOPSIS method was used to evaluate and determine the optimal remediation plan based on factors such as pollutant characteristics,remediation goals,and the current status of the contaminated plot,combined with previous experience in similar remediation projects.The results indicate that low temperature desorption has the highest relative closeness to the optimal remediation technique.It is recommended to use in-situ chemical oxidation technology for mildly polluted soil,and low temperature desorption improvement pretreatment followed by thermal desorption treatment for heavily polluted soil.This study not only provides a basis for subsequent remediation management of land parcels,but also serves as a reference for the development of remediation plans for similar types of polluted land parcels as an engineering case.
