摘　　要：异化铁还原过程广泛存在于富含Fe(Ⅲ)的厌氧环境中,是去除重金属、芳香族、有机氯等污染物的重要方式.由于异化铁还原菌独特的生理生化特征,其对有毒污染物耐受性强,在工业水处理领域具有广阔的应用前景.介绍了异化铁还原过程的电子传递机制,探讨了其对典型污染物去除机理,综述了其在工业水处理领域的应用及技术联用进展.提出未来研究应集中于改进异化铁还原过程的电子传递效率、开发耦合新型技术来充分挖掘异化铁还原在工业水处理领域的巨大应用潜力.Dissimilatory iron reduction(DIR)is widely distributed in anaerobic environments containing Fe(Ⅲ),playing an important role in degradation of pollutants(e.g.heavy metals,aro-matics,organochlorines,etc).The special biochemical characteristics of DIR bacteria grant them strong resistance to toxic pollutants,making them promising for industrial water treatment.This paper introduced the biochemical process of DIR,discussed its removal mechanism of typical pollu-tants,summarized and look forward to its application and technology coupling in industrial water treatment.It is suggested that future research should focus on improving the electron transfer efficiency and developing new technologies to couple DIR with other materials to fully exploit its potential in environmental applications.
