【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。更多还原

【Abstract】 We performed hydrodynamic numerical simulations in Laizhou Bay using the MIKE 21 and coupled the well simulated hydrodynamic model with the mass transport model.We studied the transmissions and diffusions of the pollutants discharged from the sewage outlet which was planned to be set in Weifang Haihua Industrial Park.The results showed that:the hydrodynamic exchanging capacity was relatively weak in the marine environment around the proposed location,leading to the poor dispersion of pollutants.A large area of water was affected by the high concentration of pollutants exceeding the range of the second and third type standard for functional zone.Moreover,there was 3.07km~2 of bottom sowing culture zone affected by the discharge of sewage.It was no longer suitable for mariculture in these regions which were suggested to be migrated or disqualified.更多还原
