石油污染土壤微生物联合修复技术研究进展

Progress in Research on Microbial Combined Remediation of Oil-contaminated Soil

微生物联合修复技术处理成本低、环境影响小、无二次污染,且较微生物修复或植物修复效率更高,耗时更短,成为当前的研究热点。文章介绍了植物-微生物联合修复、电动-微生物联合修复、氧化-微生物联合修复和表面活性剂强化微生物修复四种联合修复技术,简要阐述了修复机理、适用范围和工艺参数,为生物修复技术的选择提供了参考,并对以后生物修复的研究重点进行了展望。

Microbial combined remediation technology has become a hot topic due to its advantages such as low treatment cost,minor environmental impact and no secondary pollution,etc.,and it is more efficient and less time-consuming than microbial remediation or phytoremediation.This article introduced four microbial combined remediation techniques:plant-microbial combined remediation,electromicrobial remediation,oxidation-microbial combined remediation and surfactant-enhanced microbial remediation.The mechanism,application range and process parameters of bioremediation were briefly described,which provided a reference for the selection of bioremediation technology.And the future research emphasis of bioremediation were prospected.
