大多数描述配水储罐中混合和水质的可用模型都是基于瞬时和完全混合的假设。描述配送储存设施内复杂内部混合和流动交换特征的重要物理过程通常被忽略。本文介绍了严格的、明确的配蓄水质数学模型的建立和验证。 这些模型基于储罐连续体的隔间表示，并根据质量平衡原理进行分析。这些模型提供了计算短期流入和流出事件（短路）的即时反应和长期使用的渐进反应（死区）的工具。对于每个多室模型，无论化学物质种类如何，都推导出一个单一的解决方案，唯一的区别是包含了一阶衰减常数，以解释氯的降解。 这些模型可以有效地用于模拟配水储罐的内部混合特性，以及通过精确测量浓度和流量数据校准参数常数后对水质的后续影响。

Most available models for describing the mixing and water quality in distribution storage tanks are predicated on the assumption of instantaneous and complete mixing. Important physical processes describing the complex internal mixing and flow interchange characteristics that occur within distribution storage facilities have generally been neglected. This paper presents the formulation and verification of rigorous, explicit mathematical models of distribution storage water quality. These models are based on a compartmental representation of the tank continuum and are formulated analytically from mass balance principles. The models provide the tools to calculate both immediate reactions to short-term inflow and outflow episodes (short-circuiting) and gradual response to long-term use (dead zones). A single solution was derived for each multi-compartment model regardless of chemical species with the only difference being the inclusion of a first-order decay constant to account for the degradation of chlorine. These models can be effectively used for simulating the inner mixing characteristics of distribution storage tanks and subsequent effects on water quality after calibration of parameter constants from accurate measurements of concentration and flow data.
