以废治废：活化亚硫酸盐降解水中新兴有机污染物研究进展

Treating waste with waste: advances in activated sulfite treatment of emerging organic pollutants

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。而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，并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为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，为亚硫酸盐在水处理领域的应用提供理论支撑。

Abstract:

With the development of industry, more and more emerging organic pollutants are entering the water environment, posing a threat to human health and the ecological environment. The traditional advanced oxidation technology of persulfate has the problems of high application cost and ecotoxicity of residues, and finding new low-cost and environmentally friendly alternatives has become a new research direction. Sulfite itself is an industrial by-product that is considered a good alternative to persulfate due to its low cost and more environmentally friendly advantages. This paper reviews the research progress of activated sulfites in recent years from the perspective of homogeneous and non-homogeneous phases, summarizes the advantages and disadvantages of different activation modes, summarizes the application of sulfites in the treatment of emerging organic pollutants in water as well as the main factors influencing them, and points out the knowledge gaps in the existing research on the mechanism of co-oxidation between inorganic and organic pollutants and the pathway of organic pollutant degradation, and the homogeneous and non-homogeneous activation materials in practical applications. Looking forward, the research will focus on the development of new trends of non-homogeneous activation materials, practical wastewater treatment and exploration of organic pollutant degradation pathways to provide theoretical support for the application of sulfite in the field of water treatment.
