摘要
随着我国工业化进程的不断加速提质,重金属污染引起的环境风险日益凸显,其中Cr(Ⅵ)污染颇具代表性。本文围绕电子供给的不同方式,分别从输入能量和投加物质两个角度,系统梳理了近年来高效还原水中Cr(Ⅵ)技术的研发进展。指出:探索不同工艺形式的组合以降低运行成本和二次污染风险,以及以光催化、电催化和活性氢化学还原为代表的高效、清洁的还原技术,可作为未来研发的方向。
With the acceleration of industrialization in China,the environmental risks caused by heavy metal pollution have become increasingly prominent.Among them,the pollution of Cr(Ⅵ)is quite representative.Focusing on different ways of electronic supply and from the perspective of energy input and material addition,the research progress on technology for high efficiency reduction of Cr(Ⅵ)in water is systematically reviewed over the recent years.It is pointed out that the direction of future research may be exploring the combination of different process forms to reduce operation cost and secondary pollution risk,as well as efficient and clean reduction technologies represented by photocatalysis,electrocatalysis and active hydrogen reduction.
