气味化合物在饮用水源中构成了重大挑战，抵抗常规处理方法。为了解决这一问题，臭氧和基于臭氧的高级氧化工艺（AOP）由于其高氧化能力而得到广泛使用。本研究旨在全面评估直接臭氧化工艺和臭氧型高级氧化工艺的氧化效果、反应机理和潜在风险，以去除饮用水源中的各种气味化合物为目标。本文综述了典型恶臭化合物与臭氧的反应机理，并对各种高级氧化工艺的优缺点进行了深入的比较。运行参数，包括pH值，反应温度，理化水质，臭氧剂量，进行了分析，以了解其对臭氧去除恶臭化合物的影响。此外，我们简要介绍了实用的饮用水联合处理，包括臭氧和其他工艺。最后，我们提出的基本要求，因素和未来的研究努力，在开发先进的臭氧化技术，有效的气味化合物去除的挑战。总的来说，这项全面的研究为进一步推进饮用水处理战略奠定了基础，以确保向公众提供安全无异味的水。
Odor compounds pose a significant challenge in drinking water sources, resisting conventional treatment methods. To tackle this issue, ozone and ozone-based advanced oxidation processes (AOPs) have gained widespread use due to their high oxidation capacity. This study aims to comprehensively assess the oxidation effects, reaction mechanisms, and potential risks associated with direct ozonation processes and ozone-based AOPs, targeting the removal of diverse odor compounds found in drinking water sources. Our review sheds light on the reaction mechanisms between typical odor compounds and ozone, while an in-depth discussion compares the advantages and disadvantages of various AOPs. Operating parameters, including the pH, reaction temperature, physicochemical water quality, and ozone dose, are analyzed to understand their effect on odor compound removal by ozone. Furthermore, we briefly introduce practical combined drinking water treatments that incorporate ozone and other processes. Finally, we present the essential requirements, factors, and challenges for future research endeavors in developing advanced ozonation technologies for efficient odor compound removal. Overall, this comprehensive study lays the foundation for further advancements in drinking water treatment strategies to ensure the delivery of safe and odor-free water to the public.
