微生物协同Fe0氧化的环境修复作用研究进展

Advance in the integrated microbial-Fe0 treatment processes for environmental remediation—A review

摘要:

摘要: 零价铁(Fe0)具有高效还原转化多种污染物的能力，但不能实现污染物的矿化作用。微生物与Fe0 的协同作用过程，以微生物为主导，Fe0 起促进作用，可有效提高多种污染物的降解效率，实现污染物的彻底脱毒与无害化，因此利用微生物协同Fe0 氧化进行环境修复具有广阔的应用前景。本文从微生物协同Fe0 氧化的作用机理、菌种多样性及其在环境修复中的应用等研究进展进行综述，提出微生物协同Fe0 氧化的环境修复研究中存在的主要问题和重点研究方向，以期在更全面、深入地认识这一过程的基础上，充分发挥其在环境修复中的作用。

Abstract: Zero-valent iron ( Fe0 ) is very effective for the transformation of a wide variety of common environmental contaminants． No contaminant mineralization happened only by Fe0 corrosion，but the pollutants would be completely detoxified and degraded by the integrated microbial-Fe0 treatment，which represent a new generation of environmental remediation technologies． In this paper，the mechanism，microbial diversity and application of the integrated microbial-Fe0 treatment processes were reviewed．In addition，we also discussed the main problems and challenges in this filed．
