柴河水库水质水量耦合调度模型及求解

Coupled water quality-quantity dispatching model for Chaihe Reservoir and its solution

针对柴河水库作为铁岭市重要水源地受到的污染,综合考虑柴河水库目前水量调度情况及库中TP(总磷)、TN(总氮)在水库中的最大日负荷作用,建立了柴河水库水质水量耦合调度模型,并利用MATLAB进行了求解。结果表明柴河水库利用该模型进行调度即能满足对铁岭市需水量的要求,也能保证出库水质标准。此调度模型能有效地改善水库水环境质量,可供其他水库水质水量耦合调度作参考。

In accordance with the pollution of Chaihe Reservoir——the important water source for Tieling City,a coupled water quality-quantity dispatching model for Caihe Reservoir is established herein under the comprehensive consideration of the status of the water dispatching of the reservoir and the maximum loads of TP and TN in the reservoir,and then it is solved with MATLAB.The result shows that not only the requirement from the water demand of the city can be met,but the water quality standard of the outlet water from the reservoir can also be ensured,if the reservoir is dispatched with this model.Generally,the water quality of the reservoir can be effectively improved by this model,and then a relevant reference can be provided by it for the coupled water quality-quantity dispatching of the other reservoirs as well.
