- Abstract:
- For the design of sewage pumping station and pipe network project outside Tianshi University in Tianjin, the following conditions need to be considered: the elevation of the sewage pipeline at the end of the three water collection ranges cannot be connected, the construction area of the pumping station is limited, and the sewage volume changes greatly. After the comparison and selection on the proposed plans, several integrated prefabricated pumping stations are used in parallel to lift sewage to sewage treatment plant. For the design on the control of the pumping station, pressure sensors are set at the outlet and intersection of the pumping station to realize the coordination control of frequency conversion submersible sewage pumps. It overcomes the problem of pressure imbalance in the pressure sewage pipe network, and smoothly realizes the purpose of simultaneously discharging sewage from multiple areas.
