摘要
通过数学模拟及实验研究,给出二次污染水质模型参数反应动力学速率常数k、CODMn最大生成潜能ρmax的估计值,分析了水在管网流动的过程中污染物迁移转化过程,提出不同管材的极限水力停留时间,为输配水管网系统安全运营提供技术依据.
The esthnated data of secondary polluted drinking water quality model parameters-k, ρmax which represent the constant dynamic reaction rate and of the maximum CODMn produced capacity, are given through mathematical simulation and experimentation. The pollution transferring and moving courses of the flowing water in pipeline network are analyzed. The limited hydraulic retention time of different pipelines is put forward, which gives the technological basis for the safe works of the water transport and distribution systems.
