摘要针对油田采出污水外排的问题，开展了污水稀释聚合物驱油研究。
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
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
