Abstract:
Pumping station is an important link in the process of transporting water in sewage system. Optimization of pump start-stop water levels can improve the capacity of water regulation and storage of the drainage network and the efficiency of the pump. Sewage pipeline network model of a typical industrial town H was built by using InfoWorks ICM. The measured data of two pumping stations were used for calibration and verification, and the Nash-Sutcliffe efficiency coefficient and the percentage standard deviation were used to evaluate the consistency between the simulation results and the measured data at the monitoring points. The results showed that the model was basically consistent with the actual situation of the sewage pipeline network in H town. On the basis of the credible model, according to analysis of the current operation of Yunnan pumping station, Zhenbei pumping station and C Bei pumping station in H town, improvement schemes for start-stop water levels of each pumping station were proposed. The model was used to simulate the scheme and the optimal scheme was finally obtained, which was as follows: the start water level of Yunnan pumping station was -2.40 m and its stop water level was not higher than -5.99 m; the start water level of Zhenbei pumping station was -1.30 m and its stop water level was not higher than -3.96 m; C Bei pumping station was still controlled by the current start and stop water levels of the pump. The results provide a basis for the subsequent optimal operation of the drainage system in the research area.
