微生物修复石油烃土壤污染技术研究进展

Advances in bioremediation of hydrocarbon-contaminated soil

随着人民生活水平的提高,环境保护问题愈发受到人们重视。其中石油烃的土壤污染因其持续时间长、污染去除难度大而受到广泛关注。在各类修复技术中,原位微生物修复强化技术因其成本较低、环境影响小、无二次污染、可原位修复的特点成为了当前的技术热门。文中综述了生物投加法、生物刺激法、联合修复法等原位微生物修复技术,并介绍了一些典型工程案例,为原位微生物修复强化技术的选择及工程应用提供了参考,并对未来原位微生物修复强化技术的研究重点进行了展望。

With continuous improvement of people’s living standards,great efforts have been paid to environmental protection.Among those environmental issues,soil contamination by petroleum hydrocarbons has received widespread concerns due to the persistence and the degradation difficulty of the pollutants.Among the various remediation technologies,in-situ microbial remediation enhancement technologies have become the current hotspot because of its low cost,environmental friendliness,and in-situ availability.This review summarizes several in-situ microbial remediation technologies such as bioaugmentation,biostimulation,and integrated remediation,as well as their engineering applications,providing references for the selection of in-situ bioremediation technologies in engineering applications.Moreover,this review discusses future research directions in this area.
