摘要
综述了污染土壤修复过程中常见的不同种类氯代有机物的高级化学氧化技术,如芬顿氧化、过硫酸盐氧化、高锰酸盐氧化、臭氧氧化及生物化学联合氧化技术等.分析了各氧化技术的降解机理、可降解的污染物种类、适用条件以及实验室小试、中试等不同规模的研究实例及进展,展望了今后几个值得关注的研究方向,以期可以在未来的土壤修复工程中起到参考、借鉴和指导作用.
A review is provided on a variety of approaches to soil remediation by advanced chemical oxidation technologies, which are wildly used in chlorhydrocarbon contaminated sites. These approaches include Fenton reaction, persulfate oxidation, permangant oxidation, ozone oxidation, physical chemical and biological remediation and so forth. The degradation mechanisms, types of degradable contaminants, oxidant applicability, and mulitiple scale pilot studies are also analyzed. Besides, research direction in future study are proposed after sorting out excellent work done in the past, which might provide some guidance for site remediation when encountering those contaminants in the future.
