标准摘要
[中文适用范围]： 本文件规定了对采用紫外线消毒技术 (UVBWMS) 的压载水管理系统 (BWMS) 的紫外线 (UV) 反应器设计进行计算建模的方法。 计算模型用于计算紫外线减少当量剂量 (RED) 并将缩放反应器的计算 RED 与其基础反应器进行比较。 RED 使用具有给定剂量反应的生物体来测定。 注：IMO 要求验证计算模型。 使用计算模型模拟物理紫外线反应器需要验证模型（即它按预期运行并反映正确的物理约束）和验证（即产生与经验数据一致的输出）。 根据本文件开发的模型旨在验证模拟但未经测试的按比例缩放的紫外线反应器的性能，其中模拟已通过产品线内基本模型紫外线反应器的测试数据进行了验证。 由于完整的 UV BWMS 通常采用过滤器等其他处理方法，因此本文档不考虑外部子系统性能变化对整体 BWMS 的影响。 [外文原描述]： This document specifies the methodology to conduct computational modelling of ultraviolet (UV) reactor designs for ballast water management systems (BWMS) that incorporate ultraviolet disinfection technology (UVBWMS). The computational modelling is used to calculate the UV reduction equivalent dose (RED) and to compare calculated REDs of the scaled reactor to its base reactor. REDs are determined using organisms with a given dose response. NOTE The IMO requires validation of the computational model. The simulation of a physical UV reactor using a computational model requires that the model be validated (i.e. it performs as intended and reflects the correct physical constraints) and verified (i.e. produces outputs consistent with empirical data). A model developed according to this document is intended to validate the performance of simulated but untested, scaled UV reactors, where the simulation has been verified with test data from base model UV reactors within the product line. As a complete UV BWMS typically incorporates other treatment methodologies such as filters, the impact of changes to external subsystem performance on the overall BWMS is not considered in this document.
