摘要
根据台州市河网地区水体的水动力、水质特性及污染负荷,利用MIKE-11软件,建立了河网一维水动力和水质耦合模型。利用实测水位、NH3-N、COD质量浓度进行了参数的率定和验证。在水动力水质模型的计算结果的基础上,计算水环境容量及其现状入河污染物负荷,构建了台州市区河道污染物负荷历时曲线,计算出COD和NH3-N在各个流量历时区域内的削减量和削减率,旨在为平原河网地区水环境保护和水资源管理提供依据。
Based on the hydrodynamic and water quality characteristics, and pollutant load of the river networks in Taizhou City, the software MIKE-11 was adopted to establish a one-dimensional hydrodynamic and water quality coupling model. The model＇ s parameters were calibrated and verified in terms of the measured water level, NH3-N, and COD concentrations in the river networks. On the basis of the model, the water environmental capacity and the pollutant load were calculated. In addition, the pollutant load duration curve for the rivers in Taizhou City was built. The reduction amounts and reduction rates of NH3-N and COD in all flow duration regions were calculated. This study aims to provide a basis for water environmental protection and water resources management in plain river networks.
