旧金山公用事业委员会计划扩大其可持续发展能力。 Sunol Valley水处理厂（SVWTP）从120 mgd降至160 mgd，以满足 其43亿美元水系统改进计划的服务目标。工厂的关键部件 扩建项目包括建造一个新的氯气接触罐（CCT）和一个新的1750万加仑处理过的氯气罐 蓄水池（TWR）。CCT的目的是确保在较高的工厂流量下进行充分消毒 并通过控制接触水的时间来减少消毒副产物的形成 含有游离氯。CCT的规模需要最小化，以最大限度地降低施工成本，这 分析用于确定在满足消毒要求的情况下，它可能会有多小。 这个 TWR的规模是通过对需求模式的分析确定的。来自SVWTP的处理水 将在CCT和TWR之间进行氯胺化。与TWR相关的问题包括: 入口和出口，这也会影响建筑成本，并将停滞区最小化，这将 可能有助于硝化并导致氯胺残留的损失。本文综述了国内外研究现状 计算流体动力学（CFD）建模的结果，用于预测管道的水力特性 提议的CCT和TWR。包括4个参考文献、表格和图表。

The San Francisco Public Utilities Commission (SFPUC) plans to expand the sustainable capacity of its Sunol Valley Water Treatment Plant (SVWTP) from 120 mgd to 160 mgd in order to meet the level of service goals of its $4.3 billion Water System Improvement Program. Key components of the plant expansion are construction of a new chlorine contact tank (CCT) and a new 17.5 million gallon treated water reservoir (TWR). The purpose of the CCT is to ensure adequate disinfection at higher plant flows and to minimize disinfection byproduct formation by controlling the time in which the water is in contact with free chlorine. The size of the CCT needs to be minimized to minimize construction costs, and this analysis was used to determine how small it could be while still meeting disinfection requirements. The size of the TWR was determined by an analysis of demand patterns. The treated water from the SVWTP will be chloraminated between the CCT and the TWR. Issues related to the TWR were configuration of the inlet and outlet, which also impact construction costs, and minimization of stagnant zones, which could contribute to nitrification and resultant loss of chloramine residual. This paper summarizes the results of computational fluid dynamics (CFD) modeling to predict the hydraulic characteristics of the proposed CCT and TWR. Includes 4 references, tables, figures.
