【摘要】 本文综述了30多年来国内外石油污染土壤的生物修复的进展,并介绍了国内外在修复石油污染土壤方面的生物修复工艺:原位生物修复和异位生物修复。原位修复有原位地耕法和土壤气相抽提;异位修复有土壤耕作发、堆放法、堆肥法和反应器法。文章还就今后的研究方向作了阐述,指出生物修复方法作为一种费用低、效果好、对环境影响低、无二次污染的方法,是今后治理石油对土壤污染的最可行的方法。更多还原

【Abstract】 The paper summarizes the development of bioremediation of oil-contaminated soil home and abroad in the last three decades,introduces the bioremediation process for oil-contaminated soil including bioremediation in situ and ex situ.Bioremediation in situ includes land cultivation in situ and soil vapor extraction;bioremediation ex situ includes land cultivation,bio-pile,composting and bioreactor.Some suggestions are proposed for future development.This paper indicates that the bioremediation is the most feasible way to treat oil-contaminated soil in the future due to its low cost,good effect,little environmental influence and no secondary pollution.更多还原
