摘　　要：基于水工模型试验,以惠州大亚湾污水深海排放工程为例,分析了大水深条件下污水扩散器设计参数(扩散器长度、喷口射流角度、水平方位角)对污水近区稀释扩散效果的影响。实验结果表明:扩散器设计参数对污水的近区稀释扩散有显著的影响。针对大亚湾污水深海排放工程排放口水域水深条件较大的情况,喷口射流角度可以适当增大,宜控制污水排放在20°左右,水平方位角在90°左右,既能够保证污水的充分稀释混合,也能够避免污水的过早升顶和集聚。证明了在大水深条件下污水扩散器选取大角度喷口的方案是可行的。The sewage diffusion effect under deep water was carried out between different diffuser design parameters based on the hydraulic model test, and Huizhou Dayawan sewage marine disposal project was taken as an example. The experimental results show that the design parameters are significant for sewage diffusion at the near field. For Dayawan project, jet angle is controlled to be 20°, and horizontal angle is controlled to be 90°. It can not only ensure the sewage dilution and mixing, but also avoid the premature convergence and sewage lifting. It is feasible for selecting large angle nozzle under deep water.
