为了通过紫外线（UV）消毒获得隐孢子虫和贾第鞭毛虫对数灭活信用，长期2强化地表水处理规则（LT2ESWTR）将要求紫外线消毒 系统经过验证测试。在验证过程中，紫外线系统的剂量传递是根据通过紫外线反应器的流量、水的UVT和灯功率进行评估的， 使用测试微生物。进行验证的目的是为了建立产品的性能关系 以及制定剂量监测策略，以在线监测 紫外线反应器。为了应对LT2ESWTR，美国环境保护局（USEPA）正在开发紫外线消毒系统 提供紫外线（UVM）应用技术指南 公共供水系统饮用水消毒灯。UVDGM提供 根据 LT2ESWTR验证要求。 使用试验微生物在验证期间测得的剂量称为还原当量剂量（红色）。美国环保局开发了一种计算安全系数的方法，称为设备系数（EF），用于验证红色数据。EF解释了 与验证和剂量传递监测相关的偏差和随机误差。 EF用于定义水处理厂（WTP）达到目标病原体灭活要求所需的红色。 本文对使用UVDGM 2003年6月草案和2005年1月草案分析UV反应堆验证数据的UVDGM规定方法进行了全面回顾 修订本。该分析结合了设备系数（EF）计算的所有元素，并使用了在UV实验室进行的大规模UV反应器验证的真实示例 俄勒冈州波特兰的验证设施。包括3个参考文献、表格、图表。

To obtain Cryptosporidium and Giardia log inactivation credit using ultraviolet (UV) disinfection, the Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) will require that UV disinfection systems undergo validation testing. During validation, the dose delivery of a UV system is evaluated as a function of flowrate through the UV reactor, UVT of the water, and lamp power, using a test microbe. Validation is conducted in order to develop performance relationships for UV reactors as well as to develop dose monitoring strategies for on-line compliance monitoring of UV reactors. In anticipation of the LT2ESWTR, the US Environmental Protection Agency (USEPA) is developing the UV Disinfection Guidance Manual (UVDGM) to provide technical information on the application of ultraviolet light for the disinfection of drinking water by public water systems. The UVDGM provides guidance on recommended procedures for validating a UV reactor and data analysis, based on the LT2ESWTR validation requirements. The dose measured during validation using the test microbe is referred to as the Reduction Equivalent Dose (RED). USEPA has developed an approach for calculating a safety factor, known as the Equipment Factor (EF), which is applied to the validation RED data. The EF accounts for bias and random errors associated with validation and dose delivery monitoring. The EF is used to define the RED that is required at water treatment plants (WTP) to achieve the inactivation requirement for the target pathogen. This paper provides a comprehensive review of the UVDGM-prescribed methodology for analyzing UV reactor validation data using the UVDGM June 2003 Draft and January 2005 revisions thereof. The analysis incorporates all elements of the Equipment Factor (EF) calculations and using a real world example from a large-scale UV reactor validation conducted at the UV Validation Facility in Portland, Oregon.
