基于差分方程的河流污染估算动态模型研究

Dynamic Estimation Model of River Pollution Based on Differential Equations

采用"分区"的思想来计算河水的污染浓度,建立河流污染估算差分方程动态模型,并用该方法来估算采取不同污染标准时的不同的污染限额;估算河流污染到达稳定状态时所需的时间。最后用模型对黄浦江作了数值计算。

A ＂division＂ method is used to estimate the pollution of rivers, established the dynamic estimation model of river pollution based on differential equations. The method was used to estimate the different pollution standards at the different pollution limits; estimate river pollution stable condition and the time required. Finally, numerical calculations are made for the Huangpu River as an example.
