摘　　要：【目的】随着水体富营养化日益严重,饮用水中藻源性嗅味问题逐渐凸显,影响饮用水品质并对供水安全造成威胁。文章旨在综述典型藻源性嗅味物质及其主要去除工艺的现状,以有效识别水中的嗅味物质的来源并高效控制饮用水中的嗅味,从而提高饮用水品质,为供水行业的水质管理提供借鉴意义。【方法】文章首先概述了主要藻源性嗅味物质,包括2-甲基异莰醇(2-MIB)、土臭素(GSM)等的嗅味特点、理化性质和产生环境。其次,对活性炭吸附、传统氧化、高级氧化和光催化氧化等去嗅工艺的降解原理和前沿研究进展进行了系统梳理与比较,重点分析其去除机制、优缺点和适用条件。【结果】研究表明,活性炭吸附对2-MIB和GSM等嗅味物质有较好去除效果,但成本较高;氯氧化和高锰酸钾对藻类失活效果好,但会释放胞内嗅味物质;臭氧和高级氧化工艺(如紫外/过氧化氢、紫外/氯等)对多种嗅味物质有效,但易产生副产物。光催化氧化因其高效性与无污染潜力被认为是未来发展的重要方向。【结论】目前,单一工艺难以全面去除嗅味,组合工艺展示出更佳效果。未来研究应聚焦多工艺组合优化,提升去除效率,控制副产物生成,为水厂提供更科学的技术选择,保障饮用水的安全与质量。[Objective]With the increasing issue of water eutrophication,various odor substances produced by algae pose significant challenges to drinking water quality and safety.This paper aims to review the main types of algae-derived odorants and the latest advancements in removal processes to effectively identify the source of odorants in water and efficiently control odors in drinking water,so as to improve the quality of drinking water,and provide reference for water quality management in water supply industry.[Methods]The study provides an overview of the physicochemical properties and sources of key algae-derived odorants,such as 2-methylisoborneol(2-MIB)and geosmin(GSM).It then systematically compares removal processes,including activated carbon adsorption,conventional oxidation,advanced oxidation and photocatalytic oxidation,focusing on removal mechanisms,advantages,and limitations.[Results]Findings indicate that activated carbon adsorption can effectively remove 2-MIB and GSM,but it is costly;chlorine and potassium permanganate are effective in deactivating algae but may release intracellular odorants;ozone and advanced oxidation processes(e.g.ultraviolet/hydrogen peroxide,ultraviolet/chlorine)show broad efficacy in removing various odorants but may produce by-products.Photocatalytic oxidation,with its high efficiency and pollution-free potential,is highlighted as a promising future solution.[Conclusion]Single processes struggle to fully remove odorants,while combined processes offer superior result.Future research should focus on optimizing multi-process combinations to improve removal efficiency and control by-product formation,providing more reliable technical options for water treatment plants to ensure drinking water safety and quality.
