污水排海扩散器优化设计

Optimal Design of Marine Outfall Diffuser

结合上海市污水治理二期工程，介绍排海工程中扩散器水力计算的新方法，通过控制扩散器三通及喷头局部阻力系数，使各上升管出流量不均匀分配，数学模型计算结果与物理模型实测值非常吻合。

This paper presented a new hydraulic calculation method for marine outfall diffuser used in the second phase sewage disposal project in Shanghai.By controlling the minor losses coefficient of T-junction and nozzled,the uneven distribution of flow among the risers of the diffuser was achieved.The predicted values of a mathematical model were in good agreement with the results of physical model test. \ \
