石油污染土壤微生物联合修复技术研究进展

石油是一种具有生物毒性的复杂有机物,土壤中石油烃的过量积累会给生态环境和人类健康造成严重威胁。微生物联合修复技术因处理成本低、环境影响小、无二次污染等优点,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。

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

Petroleum is a kind of complex organic matter with biological toxicity. Excessive accumulation of petroleum hydrocarbons in the soil will pose a serious threat to the ecological environment and human health. Microbial combined remediation technology has become a hot research topic due to its advantages such as low treatment cost, small environmental impact and no secondary pollution, etc., and it is more efficient and less time-consuming than microbial remediation or phytoremediation. This article introduces four microbial combined repair techniques: plant-microbial combined remediation, electro-microbial remediation, Oxidation -microbial combined remediation and surfactant-enhanced microbial remediation. The mechanism, application range and process parameters of bioremediation are briefly described, which provided a reference for the selection of bioremediation technology. And the future research emphases of bioremediation are prospected.
