首都地区（CRD）向维多利亚市和 周边地区。维多利亚是加拿大不列颠哥伦比亚省的省会，人口超过100万 310,000. 在过去几年中，CRD一直在计划升级其 氯胺化处理设施。计划阶段包括调查各种 过滤和消毒策略。最终，CRD通过了一项包含 将紫外线（UV）消毒与氯化和氯胺化相结合，对其水进行消毒 治疗改善项目。 在2002年至2004年间，CRD安装了580毫升/天的紫外线发生器 消毒系统。该系统被改造成现有的供水系统和 2004年3月委托。这篇论文描述了这个项目，这个项目 以及设计团队面临的一些挑战，包括:紫外线透射率；水力学；还有，控制。包括7个参考文献、表格、图表。

The Capital Regional District (CRD) supplies water to the City of Victoria and the surrounding area. Victoria is the provincial capital of British Columbia, Canada, and has a population of over 310,000. Over the past several years, the CRD has been planning upgrades to its chloramination treatment facilities. The planning stage involved investigating various filtration and disinfection strategies. Ultimately the CRD adopted a plan incorporating the use of ultraviolet (UV) disinfection combined with chlorination and chloramination for its water treatment improvement project. Between 2002 and 2004, the CRD has implemented the installation of a 580 ML/d UV disinfection system. The system was retrofitted into the existing water system and commissioned in March 2004. This paper describes the project, the project implementation, and some of the challenges that faced the design team, which included: UV transmittance; hydraulics; and, control. Includes 7 references, table, figures.
