大型污水输送系统的水力模拟模型

A Hydrawlic Simulation Model for Large-Scale Sewerage Conveyance Sytem

利用 infoWorks 软件模拟了上海市污水治理二期工程的水力学特征。根据实际运行数据校正了阻力系数,并对模型进行了客观验证。结果表明:采用的水力模型良好地体现出上海市污水治理二期工程污水输送系统的运行状况。采用自动水泵运行顺序可以获得比手动控制更稳定的水位。非满流存在于 M2泵站前的某些管段中。为了提高整个系统的大流量输送能力,SA 和 SB 泵站之间的管线调储能力可充分利用。

The Hydraulic characteristics of Second Shanghai Sewerage Main Conveyor was simulated by using Infoworks.The resistance coefficients were calibrated,and the output was validated based on operative data.The result demonstrates that the operation of this large-scale sewerage conveyance system can be properly forecasted by this hy- draulic simulation model.More stable water levels can be achieved by using the automatic pump operative sequence rather than manual control.Partial flow conditions exist in some sections of main conveyor in before M2 Pumping Sta- tion.In order to enhance the transportation capacity of the whole system in high flow condition,full utilization of the storage capability of the main conveyor between SA and SB Pumping Station is preferred.
