摘要
借助于水工模型试验 ,分析了上海市污水治理二期工程长江口潜没多孔排放时扩散器设计参数 (射流角度、喷口水平方位角、喷口个数、喷口布置排数、喷口上加导流管、上升管间距 )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 ,针对白龙港排放口水域 ,喷口射流角度宜控制污水排放在 0°或 5°左右 ,喷口个数取不多于 16个 ,水深处分二排布置 。
The study on dilution and dispersion at Changjiang Estuary was carried out in this paper according to the hydraulic model tests. The influence of diffuser parameters (e.q. jet angle, port horizontal angle, number of nozzle, port arrangement, leading tube on the port, riser space) on dilution was analyzed. The experimental results show that design parameters of diffuser have very important influence on wastewater dilution and dispersion at the near field. For Bailonggang outfall, jet angle was controlled to be 0 degree or 5 degree, nozzle number is no more than 16, which were arranged in two rows in deep water, one row in shallow water.
