| 摘 要： | 通过环境水槽实验获取了COD和NH3-N衰减系数与流速效应之间的定量关系式,建立了反应污染物衰减与流速动态变化的二维水流水质数学模型。以广东省飞来峡水利枢纽库区为例,利用二维水流水质数学模型和常规的完全混合模型对库区COD和NH3-N纳污能力进行了计算。结果表明:前者计算的纳污能力大于后者,其计算出的主流区纳污能力为库湾区的8.4倍左右。分析认为二维水流水质数学模型计算结果更符合实际。

| Abstract: | Quantitative relation has gained through the environmental water tank experiment between degradation coefficient of COD and NH3-N and the velocity effect, and a 2-D hydrodynamic and water quality coupling model has been established. Taking the Feilaixia reservoir water carrying capacity calculation as a study case, the reservoir water carrying capacity of COD and NH3-N has been calculated by 2-D hydrodynamic and water quality coupling model. The results show that the water carrying capacity calculated by 2-D hydrodynamic and water quality coupling model are more than complete mixing model. Moreover, the water carrying capacity of mainstream area 8.4 times is larger than reservoir bay. It is shown that the 2-D water quality mathematical model is much feasible. |
