摘要
随着工业的发展,越来越多的新兴有机污染物进入水体环境,对人类健康和生态环境造成威胁。传统的过硫酸盐高级氧化技术存在应用成本较高、残留物生态毒性等问题,寻找低成本的环保替代品成为新的研究方向。亚硫酸盐本身是工业副产物,因其低成本且环保的优点被认为是过硫酸盐良好的替代品。该文从均相和非均相角度综述了近年来活化亚硫酸盐的研究进展,归纳了各种活化方式的优缺点,总结了亚硫酸盐处理水中新兴有机污染物的应用以及主要的影响因素,指出了现有成果在无机与有机污染物共氧化机制及有机污染物降解路径上的研究空白,均相与非均相活化材料在实际应用中的局限性。最后,提出未来的研究方向,应探索非均相活化材料的发展新趋势、实际废水处理和有机污染物的降解途径。
Along with industrial development,more and more emerging organic pollutants enter the water environment and pose a threat to human health and ecological environment.The traditional advanced persulfate oxidation technology has the problems of high application cost and residue ecotoxicity,thus finding new low-cost and environmentally friendly alternatives has become a new research direction.Sulfite itself is an industrial by-product and is considered a good alternative to persulfate due to its low cost and more environmentally friendly advantages.Here,the research progress on activated sulfites in recent years were reviewed from the perspective of homogeneous and heterogeneous phases,with the advantages and disadvantages of different activation modes introduced.The application of sulfites in the treatment of emerging organic pollutants in water as well as the main influencing factors was summarized.The existing research gaps in the co-oxidation mechanism of inorganic and organic pollutants,the degradation path of organic pollutants and the limitations of homogeneous and heterogeneous activated materials in practical applications were pointed out.Finally,the future research direction was discussed,suggesting exploration should be focused on the new trend of heterogeneous activated material development,the actual wastewater treatment and the degradation of organic pollutants.
