    摘要:

    为改善台州城区水生态环境,确定对台州城区生态补水的规模,应用MIKE 11水环境模型软件建立河网水量水质耦合模型,研究河网水动力变化对水质改善的影响,对模型进行率定、验证,并预测8种不同工况条件引水后的水质状况,以水环境质量改善后降低的污水处理费用作为经济效益指标,以泵站运行费用作为成本指标,计算引水流量与工程净效益之间的定量关系,最后分析得到最佳引水流量,旨在为确定、优化台州市区生态补水流量、治理城市水污染问题提供决策依据。

    Abstract:

    In order to improve the water ecological environment of Taizhou urban area, and determine the scale of ecological water supplement in the area, the water environment MIKE 11 software was used to establish a river water quantity and quality coupling model to study the influence of hydrodynamic change on water quality improvement. And then the model was calibrated and verified. The situation of water quality after water diversion of eight kinds of different working conditions was predicted. Taking the reduced wastewater treatment costs after the quality of water was improved as the economic benefits indicators, and pump operating costs as the cost index, the quantitative relationship between the flow of water diversion and the net benefit of the project was calculated, and the optimal flow of water diversion was obtained. The aim of this study is to provide a scientific basis for determining and optimizing ecological water supplement and the control of water pollution in Taizhou urban area.
