    摘要:

    沿海地区污染物排放对近海水环境影响较大。本文通过建立平面二维水动力模型和污染物扩散模型,以江苏沿岸主要污染物氨氮为例,对王港河口地区水动力条件和污染物扩散进行了模拟。模拟结果显示,在污染物排放点水深小于10m时,涨潮时排放污染物的扩散、稀释作用较落潮时排放更明显,10m水深以上排放点可以不考虑涨落潮影响;受大丰港等沿岸建筑物的影响屏蔽作用,1m水深位置涨潮时排污污染物滞留最明显;随着排污位置水深增加,污染物扩散效果明显,在水深10m位置扩散作用有明显增强。模拟得出在考虑污染物影响范围的条件下,排污位置点选择10m附近较合理。

    Abstract:

    Coastal pollutant discharge has great influence on near sea water environment.In this paper, through the establishment of two-dimensional hydrodynamic model and pollutant diffusion model,take Jiangsu coast’s main pollutants of ammonia for example, the Wang-gang estuary area hydrodynamic condition and pollutant diffusion was simulated. The simulation results show that when the water depth of pollutant discharge point is less than 10m, the diffusion and dilution of pollutants at high tide are more obvious than When the ebb tide.The pollutant discharge point above 10m depth can ignore the influence of fluctuation tide.Affected by the shielding effect of dafeng port, the pollutant emission was most obvious when the water depth of pollutant discharge point is 1m at high tide. With the increase of the depth at the discharge location, the pollutant diffusion effect is obvious, and the diffusion effect at the depth of 10m is obviously enhanced. The simulation results show that it is reasonable to choose the location near 10m when considering the influence range of pollutants.
