土壤铬污染生物修复研究现状

Research Status of Bioremediation of Chromium Contaminated Soil

论述了铬污染土壤生物修复(包括植物修复、微生物修复及植物与微生物联合修复)的研究现状,之后介绍了不同修复方式的优势及局限性。此外,还重点阐述了典型修复植物李氏禾(Leersia hexandra Swartz)和其他修复植物,以及微生物修复方式中生物吸附和生物还原。最后对土壤铬污染生物修复前景进行了展望。

The research status of bioremediation of chromium-contaminated soil was discussed, including phytoremediation, microbial remediation and plant-microbe remediation, and then the advantages and limitations of different remediation methods were introduced. In addition, the typical restoration plant of Leersia hexandra Swartz and other restoration plants, as well as the microbial restoration methods including the biosorption and bioreduction, were also discussed. Finally, the development trend of bioremediation of chromium contaminated soil was prospected.
