恒定横流底部多孔排放近区污水稀释扩散效果因素研究
- Dilution and dispersion of the near field in constant horizontal flow and multi port bottom discharging
- 摘要：借助于人工模型试验,分析了恒定横流底部多孔排放时扩散器设计参数(射流角度、射流速度、喷口个数)、上升管间距)及环境参数(环境水深、环境流速)对污水近区稀释扩散效果的影响,实验结果表明,除了环境条件对污水稀释扩散效果影响明显之外,扩散器设计参数对污水的近区稀释扩散也有显著的影响,针对白龙港排放口水域,喷口射流角度宜控制在10°左右,喷口个数取16个。
- Abstract：Dilution and dispersion in constant horizontal flow and bottom multi port discharging was studied in accordance with the hydraulic model test.The influence of diffusion parameters (jet angle,jet velocity,number of nozzle,riser space) and environmental parameters (water depth,water velocity) on dilution were analyzed.The experimental results show that environmental parameters have prominent effects on wastewater dilution and dispersion,in addition to that,diffuser design parameters have significant influence on wastewater dilution and dispersion.For Bailonggang outfall zone,jet angel is 10° or so,nozzle number is 16 or so.
