石油污染土壤的生物修复技术研究进展

Research Progress of Bioremediation for Petroleum-Contaminated Soil

随着石油工业的不断发展,石油污染土壤的治理问题已经成为当今研究者关注的焦点问题。相比于物理方法和化学技术,生物技术因为其高效、无毒,且对环境不产生明显的干扰而被广泛应用于原位和异位修复油污土壤。生物修复技术主要包括植物修复、微生物修复、植物-微生物联合修复等方法,通过对这些技术的优缺点进行比较,展望了今后土壤石油污染修复的发展趋势和研究重点。

As the development of petroleum industry,the treatment of hydrocarbon-contaminated soil is concerned by researchers.Bioremediation technology was widely applied in in-situ and ex-situ operation because of the advantage of high efficient,no toxicity and no significant disturb on the ambient environment.Merits and faults were judged by compared these technologies,the trend and oudooks of hydrocarbon contaminated soil remediation were provided.
