摘　　要：阐述了上海市污水治理二期工程白龙港排放口水域的特殊条件,通过局部和整体模型试验,研究三通、喷头局部参数等对喷头阻力系数的影响。试验结果表明,控制三通及各上升管的局部阻力系数,可以实现上升管流量不均匀分配。The specical environemntal condition of Bailong Gang Outfall of Shanghai Sewage Project(phase-Ⅱ)——the largest sewage project in China so far is presented.Through physical model experiments,the T-junction and nozzle's effect on coefficient of spray nozzles was studied.The test results show that by controlling the T-junction and riser tube's resistance coefficients,the unbalanced riser flow distribution has been achieved.
