滏阳河东武仕水库至苏里桥段水质模型研究

Research on the Water Quality Model of Dong Wushi Reservoir to Suli Bridge,Fuyang River

近些年来,随着经济发展及工业化进程的加快,滏阳河水环境污染问题日趋严重。通过以氨氮、挥发酚主要污染物为例,根据河流水动力学特性及污染物输运特性,建立了滏阳河东武仕水库至苏里桥段的一维河流水质模型;并运用有限差分法对其求解。结果表明,运用该水质模型对包含马电闸上游桥、张庄桥、联纺桥、苏里桥四个断面在内的模拟河段的氨氮、挥发酚浓度进行模拟,得出的模拟值和实测值的相对误差较小。由此说明,滏阳河东武仕水库至苏里桥段的一维河流水质模型可较好地反映该模拟河段的水质变化状况,对滏阳河水污染的科学治理和水环境的保护与修复具有一定的指导意义。

With the economic development and the acceleration of industrialization process in recent years,the water contamination of Fuyang River becomes increasingly serious.According to the characteristics of river water dynamics and pollutant transport,ammonia nitrogen and volatile phenol,the main pollutants for example,one-dimensional river water quality model of Dong Wushi Reservoir to Suli Bridge,Fuyang River is established,which can be solved by the finite difference method.It turned out that using this water quality model to simulate the concentration of ammonia nitrogen and volatile phenol in the simulated reach which consists of Ma Dianzha Upstream Bridge,Zhangzhuang Bridge,Lianfang Bridge,Suli Bridge,the relative errors of simulative values and measured values are all relatively small.It implied that the one-dimensional river water quality model of Dong Wushi Reservoir to Suli Bridge,Fuyang River can better reflect the change in the simulated river water quality,which will be instructive to the scientific management of Fuyang Rver water contamination,as well as the protection and restoration of Fuyang River water environment
