摘要
近年来,由嗅味物质引发的水污染事件频发,高效去除水中嗅味物质已成为水处理行业面临的挑战之一.高级氧化工艺以其反应速率快和处理效果好,被广泛用于治理含嗅味物质的水体.文章首先阐述了水中嗅味物质的来源及特点,其后根据氧化降解水中嗅味物质过程中起主导作用的自由基种类,介绍了传统高级氧化和基于过硫酸盐的高级氧化工艺的优缺点,重点分析了基于不同活化方式的过硫酸盐高级氧化工艺的研究动态,并探讨了水中嗅味物质的降解特性和机理.最后对过硫酸盐高级氧化工艺去除嗅味物质的未来发展进行了总结和展望,以期为水中嗅味物质的深度处理提供一定的理论基础与技术参考.
Abstract
In recent years,the water pollution caused by taste and odor compounds has occurred frequently,and the efficient removal of taste and odor compounds in water has become one of the challenges for the water treatment industry.The advanced oxidation process(AOPs)is widely used to treat the water containing taste and odor compounds because of its fast reaction rate and good treatment effect.In this paper,the sources and characteristics of taste and odor compounds in water are described.Then the advantages and disadvantages of traditional AOPs and persulfate-based AOPs are respectively introduced,according to the dominating radicals species for the degradation of taste and odor compounds in water.Sequentially the research developments of persulfate-based AOPs based on different activation methods are analyzed specifically,and the degradation performance and mechanism of AOPs are discussed.Finally,the future development of persulfate-based AOPs for the removal of taste and odor compounds is summarized and prospected.It is expected to provide atheoretical basis and technical reference for the advanced treatment of taste and odor compounds in water.
