摘要
铁具有活泼的化学性,不仅可以通过化学反应直接降解有毒有害物质,而且可以通过氧化还原过程为微生物提供电子供体,提高微生物的功能活性,从而促进毒害物质的降解转化。近年来,铁介质驱动下的污染治理技术取得了一定的进展。在分析铁介质改善废水可生物降解性的作用原理的基础上,重点综述并讨论了铁介质与微生物共驱动的废水生化处理技术的发展,并对其所面临的问题和挑战进行展望。
Zero-valent iron (ZVI) is an element of active chemical property. It will react with the toxic and harmful pollutants through the directly chemical reaction, and also act as the electron donor for microbial respiration through the redox process. ZVI can improve the function of the microbes and promote the transformation of the toxic pollutants. In recent years, some developments have been made in ZVl-driven wastewater biotreatmcnt technologies. The mechanisms underlying the improvement of the biodegradability of wastewater by ZVI were analyzed. The progress as well as the problems and challenges of the wastewater treatment technologies co-driven by ZVI and microorganisms were reviewed and discussed.
