摘要
中国的土壤污染现状不容乐观,石油污染造成的环境问题正逐渐引起人们的重视。近年来由于具备修复成本低、无二次污染等特点,生物修复技术越来越多的应用于土壤石油污染的修复。文章就石油污染物的主要污染途径、污染机理和主要的修复技术进行综述,着重对生物通风、投菌法、生物喷射、土地耕作、生物堆、生物反应器等生物修复技术进行综合阐述,重点介绍了不同生物修复技术的修复原理、适用条件、研究进展。结合目前的研究现状和工程应用对今后土壤石油污染的生物修复技术发展进行了展望。
Soil contamination is one of the most important environmental problems in China,which caused by oil pollution has been gradually attracted people's attention in recent years.Bioremediation has been applied to repair oil-contaminated soil more and more often due to its cost-effective,no secondary pollution,etc.This review summarized the main contamination pathways,mechanisms and remedial technologies of oil-contaminated soil,and focused on the statement of bioremediations such as bioventing,bioangmentation,biosparging,land farming,biopile,bioreactor,etc.Repaired mechanisms,application conditions and research progresses of different bioremediations have been made a detailed introduction.Besides,prospect of the development of bioremediations for oil-contaminated soil alsohas been given combined with the present research status and technical applications.
