【摘要】：基于Mike21模型,建立了莱州湾附近海域的水动力计算模型,在对潍坊海化工业园区拟建排污口海域水动力计算结果验证正确的基础上,将水动力模型耦合物质输运模型,对工业园区拟建排污口排放污染物质的输移扩散进行数值模拟研究,研究结果显示:污水排海点拟建位置附近海域的水动力交换能力较差,在拟建污水排海点排放污水时,排放污染物的输移扩散造成较大面积的超标水域,影响的二类及三类海水水质功能区的最大面积分别为4.11km~2和2.36km~2,并影响附近3.07km~2水域底播养殖区。
[Abstract]:Based on the Mike21 model, the hydrodynamic calculation model of the sea area near Laizhou Bay is established. The hydrodynamic model is coupled with the mass transport model on the basis of verifying the hydrodynamic calculation results of the proposed sewage discharge outlet in Weifang Haihua Industrial Park. A numerical simulation study on the transport and diffusion of pollutants discharged from the proposed sewage outlet in an industrial park is carried out. The results show that the hydrodynamic exchange capacity of the sea near the proposed site of sewerage is poor, and the proposed sewerage point is used to discharge sewage. The transport and diffusion of pollutants resulted in a large area of water exceeding the standard. The maximum areas of the second and third types of seawater water quality functional zones were 4.11km~2 and 2.36 km2, respectively, and the bottom seeding culture areas in the nearby 3.07km~2 waters were also affected.
