基于MIKE21的渤海湾海水淡化浓盐水排海盐度场分布研究

Study on the salinity distribution of brine discharge from seawater desalination plant in the Bohai Bay based on MIKE21

运用MIKE21模型搭建计算网格,选取合适的计算参数,对渤海湾典型潮期、不同规模和位置海水淡化工程浓盐水排海后的盐度场分布进行了初步的模拟研究,计算了盐度升高面积。结果表明,合理选择海水淡化工程浓盐水排放口位置和排放时期,可以避免和减少浓盐水排放对海洋环境的影响。

The paper simulates the distribution of brine discharge from seawater desalination plants of different scales and locations in the Bohai Bay during different tidal-seasons by constructing the computing grid and selecting appropriate calculation parameters based on MIKE21. The results show that the reasonable selection of the brine outlet and discharge time by seawater desalination plants can avoid and reduce their significant effect on the marine environment.
