摘要
通过对水库恒定时间连续污染源输移扩散特征的分析 ,在其简化条件下求得一维水质模型方程的解析解。结合河道型水库断面几何参数的沿程变化规律 ,给出了 2座水库沿程BOD5浓度分布 ,并分别将解析计算结果与相应水库的一维水质数值模型预测值进行比较 ,沿程BOD5浓度分布吻合良好。
With analysis of transport diffusion characteristics of constant and continuous pollutants of reservoir,the analytical solution of one dimensional water quality model equation under simplified conditions in given.Combine with the changing laws of river shape reservoir's cross section geometric parameter,the BOD 5 concentration distributions of two reservoirs are offered.By comparing the analytical calculation results with the prediction values of one dimensional numerical model of two corresponding reservoirs,it can be found that the BOD 5 concentration distributions along the river are quite identical.
