摘　　要：以江西某地原化工企业污染地块为修复对象,介绍了组合修复技术在大型有机污染场地的应用情况。该场地污染物主要为石油烃、苯、苯酚类和多环芳烃类化合物,主要采用常温热解析技术、化学氧化技术、异位热脱附技术的组合技术对不同污染程度的地块进行分类治理修复。采用组合修复技术后,可实现修复后土壤中相关有机污染物浓度降到修复目标值以下,该组合修复技术可广泛应用于国内污染土壤修复。This paper introduces the application of combined remediation technology in large-scale organic contaminated site,taking the contaminated site of a local chemical industry enterprise in Jiangxi province as the remediation object.The major pollutants at the site were petroleum hydrocarbons,benzene,phenols and Polycyclic aromatic hydrocarbon compounds,the combined technologies of ambient temperature thermal analysis,chemical oxidation and ectopic thermal desorption were used to treat and restore the plots with different pollution levels.The combined remediation technology can reduce the concentration of related organic pollutants in the contaminated soil to below the remediation target.The combined remediation technology can be widely used in the remediation of contaminated soil in China.
