紫外消毒系统有效辐射剂量测试方法研究进展

近年来,紫外消毒技术在水处理领域的应用越来越广泛,然而关于其辐射剂量的测试方法在国内外的发展还较为缓慢,特别是目前国内还没有机构能够采用标准的生物剂量法来对紫外消毒系统内部的有效辐射剂量进行验证. 因此介绍了国际上几种主要的紫外剂量测试方法,包括生物剂量法、化学法和模型计算法,并分析了各自的优缺点和应用中存在的问题,同时探讨了几种新开发的测试方法及其应用前景,以期为紫外消毒技术在水处理领域的推广应用提供支持.

Research progress on the effective dose measurement methods for UV disinfection facilities

In recent years, ultraviolet (UV) exposure has been increasingly applied in disinfecting drinking water and wastewater. However, the progress on the measurement methods for the effective UV dose is limited both in China and abroad. In particular, there is no organization in China that can provide the effective dose validation to UV disinfection systems by use of the standard biodosimetry at current. In this paper, the main validation methods, including biodosimetry, chemical actinometry, and mathematical model calculation, are introduced with comparative discussion of their respective pros and cons in application. Moreover, several recently-developed validation methods are presented with their application perspectives envisioned. This work is expected to support the application and dissemination of UV disinfection technology in water and wastewater treatment.
