包气带-地下水石油烃污染及其原位生物修复潜力表征

摘要

包气带-地下水石油烃污染是全球普遍存在的环境问题,原位生物修复可同时有效修复包气带和地下水,对有效控制石油烃污染有重要意义.介绍了石油烃的组成、危害与分布形态,分析了石油烃原位生物修复过程,指出了通用型生物传感器可用于检测石油烃生物可利用性、表征石油烃生物修复潜力,并在总结研究进展的基础上,展望了深入的探索方向.%Petroleum hydrocarbon pollution in the vadose-groundwater system has become a globally ubiquitous environmental problem,in-situ bioremediation can successfully remediate the vadose and groundwater at the same time,which has great significance to control the pollution of petroleum hydrocarbon effectively.Introduction of the composition,including dangers and distribution of petroleum hydrocarbon,was presented,the process of petroleum hydrocarbon bioremediation was analyzed,in addition,the bioavailability of petroleum hydrocarbon and the poten-tial of its bioremediation,which could be detected and characterized by the universal biosensor,were also pointed out.At last,the further exploration directions were prospected on the basis of summarizing the research progress.
