本研究首先建立了二维水动力学模型和污染物输运模型。实验验证了模型的可行性。通过水动力学模型和污染物扩散模型，对渤海湾污染物扩散进行了数值模拟。得到了污染物排放的扩散特性。同时，从化学需氧量、亚硝酸盐氮、总磷含量、重金属含量等方面分析了浅水水质现状。
In this study, a two-dimensional hydrodynamic modeling and pollutant transport model were firstly established. The experiments verify the feasibility of the models. Through the hydrodynamic and the pollutant diffusion model, the numerical simulation of the pollutant diffusion in Bohai Bay is simulated. The diffusion characteristics of pollutant emission were obtained. At the same time, we analyzed the present situation of shallow water quality from chemical oxygen demand, nitrite nitrogen, total phosphorus content, and heavy metal content.
