苏州河水质模型

 

(1)水动力模型:

                        

式中,A为过水断面面积;Q为流量;u为断面时均流速;agaraw分别是纵向重力加速度,阻力作用项和风引起的纵向作用项。

(2)水质模型:

           

式中,C5C1C6分别是CBODNH3-NDO的浓度(mg.L-1);Cs为饱和溶解氧浓度(mg.L-1);k2为大气复氧系数;kdkn分别是含碳有机物和含氮有机物的氧化速率(d-1);Vs3为水体中有机物的沉降速率(m.d-1;SOD为底泥沉积物耗氧(g.m-2.d-1;fD5fD1分别是溶解态含碳有机物占总的含碳有机物和溶解态含氮有机物占总的含氮有机物的比例;Ex为综合扩散系数(m2.s-1);D为水深(m);u为河流纵向流速(m.s-1)。
