| 摘 要： | 本文定量地研究了北方河流封冻期BOD-DO的动态变化规律。提出了一种描述这一动态变化规律的数学模型形式,并且根据在图们江上收集到的实测数据,利用参数估计方法确定了模型中的耗氧系数K_1、复氧系数K_2和BOD沉淀-再悬浮系数K_3.通过实测数据对该模型进行检验的结果证明,它能较好地反映封冻期河流中的BOD-DO动态,可以做为这一时期水质预测与控制的基础。 用数学模型来描述封冻期河流中BOD-DO的变化规律尚属初次,所提出的模型结构形式仍有待于进一步完善。

| Abstract: | BOD-DO dynamics for rivers in Northern China during freeze season were investigated. One type of mathematical model which can be used to describe the dynamics was proposed and parameters:deoxygenation rate K1, reaeration rate K2, BOD-DO sedimentation and resuspension rate K3, were determined by a parameter estimation method using the field data based on the Tumen River. Validation of the model shows that the model can describe BOD-DO dynamics better during that season and therefore can be used with the purpose of prediction and control of the Tumen River quality. |
