摘　　要：紫外线(UV)消毒作为绿色、高效、无次生环境风险的物理消毒技术,已被广泛应用于不同水的消毒中。然而UV技术在我国推广过快,故存在从业者对关键原理和方法缺乏了解的情况,导致UV消毒可靠性不佳。介绍了UV消毒可靠性的关键因素UV辐射剂量的基本概念以及实验室和工程反应器中的剂量概念,进而综述了目前分别基于物理、化学和生物方法的光学检测器法、化学感光剂法和生物剂量法,对比阐述各方法的优缺点、应用方法和实际应用场景。同时探讨了目前UV水消毒剂量应用过程中存在的基本概念未普及、测试方法应用不准确以及长期监控手段不完善3个主要问题,为UV水消毒技术可靠性保障提供参考。UV disinfection is a green,efficient,and environmentally safe method widely used for water treatment.However,its rapid adoption in China has led to a lack of understanding among practitioners,resulting in poor reliability.This study introduced the key concept of UV fluence and its application in both laboratory and engineering settings.It also reviewed optical detector methods,chemical actinometer methods,and biological dosimeter methods,comparing their advantages,disadvantages,and practical applications.Additionally,it discussed three main issues in UV disinfection:Lack of widespread understanding,inaccuracies in testing methods,and deficiencies in long-term monitoring.These insights aimed to enhance the reliability of UV disinfection in water treatment,and providing a comprehensive perspective for practitioners.
