饮用水在蓄贮过程中二次污染数学模拟与应用研究

摘要

A concept of potential maximum generative capacity(Cmax) of pollutants in warer was proposed in construction of a dynamic mathematical model simulation the secondary opllution of drinking water in storage and transportation and CODmn was elected as indicator to estimate the secondary opllution of drinking water and to control the water quality.The parameters of the model hace been approved by experimental research. The maximum retention time (Tlim) in water reservoir(or tank)decided by the model might be helpfol to avoed the secondary pollution in water teservoir design.%建立了饮用水在蓄贮过程中二次污染水质变化动力学模式，提出水中污染物最大生成潜能概念Cmax，并将CODMn作为饮用水二次污染水质评价和控制指标，且通过试验对模型中的参数进行了估计。应用模型确定了水在水池(箱)中的极限停留时间Tlim可作为防治二次污染水池(箱)设计和选型参考依据。
