摘要: 简要介绍了疏水性有机污染物(HOCs)在土壤环境中积累产生的危害及应用生物表面活性剂(BS)修复HOCs污染土壤的优势。阐明了BS修复HOCs污染土壤的主要机理:BS对HOCs的增溶作用、BS促进土壤中HOCs的解吸、BS促进土壤中HOCs的生物降解。分析了BS的种类及含量、污染土壤对BS的吸附、土壤本身的理化性质等因素对土壤生物修复的影响。探讨了HOCs污染土壤生物修复的发展方向及应用前景。

Abstract: In this paper, the hazards of hydrophobic organic contaminants (HOCs) accumulation in soil environment and the advantages of applying biosurfactants in the remediation of HOCs-contaminated soil were briefly introduced, the main remediation mechanism of biosurfactants, i.e., promoting the dissolution, desorption, and biodegradation of HOCs was elucidated, and the effects of the type and concentration of biosurfactants and the physical and chemical properties of soils on the remediation were analyzed. The prospects of the application and development of biosurfactants in the remediation of HOCscontaminated soil were also discussed.
