MIKE11模型在台州市区河网纳污能力计算中的应用

Evaluation of Assimilative Capacity in River Network Based on MIKE11

应用MIKE11模型模拟台州市区河道水质,计算了河道水环境容量,并以流域污染物总量控制为核心,根据收集的水文和水质数据构建台州市区河道COD与NH3-N的负荷历时曲线,计算最大日负荷与多年平均允许负荷,并在污染源之间、不同水文年进行污染负荷分配.建议今要收集更多的实测样本资料,并在构建负荷历时曲线模型时单独处理河岸污染源涉及范围.

The model of MIKE11 is applied to simulate the river water quality in urban Taizhou,and its assimilative capacity is also calculated. The load duration curve of COD and NH3-N in urban rivers is constructed based on the selected data on hydrology and water quality in Taizhou,taking the basin pollutant control as the core. The maximum daily load and average allowable load are calculated,and the pollution load distribution is also discussed in pollution sources,and different hydrological years. Suggestions are recommended in this paper,asking for more observed data,and clear scope in separate treatment of river pollution sources when constructing the load duration curve model.
