| 摘 要： | 本文以渤海湾为例，运用MIKE3 FM数值模拟软件，建立了天津港附近海域浓盐水排海三维盐度扩散模型，模拟了无扩散器、有扩散器（一字型、Y型、T型），以及不同端口间距和出口流速扩散器条件下浓盐水排海后盐升扩散分布情况。研究结果表明：扩散器能够显著增强浓盐水扩散稀释效果，对于研究海域3种形状扩散器扩散稀释效果相近；适宜的端口间距和出口流速设计将提升扩散器的扩散稀释效果。相关研究结论可为科学优化海水淡化浓盐水排海方式，推动海水淡化与海洋环境和谐可持续发展提供技术支撑。

| Abstract: | Taking Bohai Bay as an example, using MIKE3 FM numerical simulation software, a three-dimensional salinity diffusion model
for brine discharge to the sea near Tianjin Port was established. The salinity distribution of non-diffuser, I-shape, Y-shape, and T-shape
diffusers were simulated, and I-shape diffusers with different port distances and exit velocities were compared. The results showed that the
diffuser can significantly enhance the diffusion and dilution of brine, and the diffusion and dilution effect of three shapes diffusers were
similar for the study area. Appropriate port distance and exit velocity design will improve the diffusion and dilution effect of the diffuser.
The conclusions can provide technical support for scientific optimization of desalinization of concentrated brine to the sea and promote the
sustainable development of desalinization and marine environment. |
