摘要
原位化学氧化在去除一些难以生物降解的污染物(如三氯乙烯)方面有着简单、快捷、彻底的优点,文章综述了2种环境友好的氧化剂过氧化氢和过硫酸钠在修复地下水污染的进展。主要从2方面进行文献的追溯跟踪,总结归纳:一方面是过氧化氢和过硫酸钠催化活化产生自由基的机理;另一方面是影响这2种氧化剂去除地下水氯代烃等有机污染的主要因素。最后提出了这2种氧化剂联合氧化的机理研究及应用上存在的问题和展望,为今后的研究工作提供了切入点和参考。
In situ chemical oxidation used in the removal of difficult biodegradable pollutants such as tnchloroethylene has the advantages of simple, quick and complete, so this paper reviews the progress of two environmental friendly oxidants including hydrogen peroxide and sodium persulfate to clean-up groundwater pollution. The mechanism of hydrogen peroxide and sodium persulfate catalytic activation to generate free radicals as well as main affecting factors of the two oxidants on removing chlorinated hydrocarbons organic contamination in groundwater were reviewed and summarized. Finally, the problems and prospects about the mechanism and the application of both oxidants using together were proposed, which would provide a starting point and reference for future research.
