数学模型在水质预测中的应用

Application of mathematical model for water quality prediction

拟建石佛寺水库位于辽河干流，属大型水利工程。在水库及下游河道水质主要污染物预测中，首次采用一维多点源稀释自净数学模型和完全混合式数学模型，定性、定量地模拟预测水库建成后水质变化规律。本数学模型适合辽河水系特点。

Shifusi Reservoir is large hydraulic project planning construction at Liaohe River. In prediction of the water quality and major pollutant for the reservoir and downstream channel, a mathematical model of one-dimension, points source, diluting and self-cleaning, along with one of fully mixing type is used for the first time. The variation law of water quality is qualitatively and quantitatively simulated and predicted after the reservoir is built. The model is fit for the Liaohe river system and it is even more reasonable and applicable than before.
