大型污水输送系统的水力模拟模型

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 ,采用的水力模型可以很好地体现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 ,为了提高大流量下整个系统的输送能力 ,SA和M2泵站之间的管线调储能力可充分利用。

Hydraulic simulation model of large-scale sewerage conveyance system

The Hydraulic characteristics of Second Shanghai Sewerage Main Conveyor were 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 hydraulic 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 before M2 Pumping Station. 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 M2 Pumping Station is preferred.
