What is a comprehensive pumping station?

With the continuous improvement of people's living standards and production methods, the consumption of water resources is also increasing, which is followed by the problems of water pollution and large amount of sewage discharge, which poses new challenges to the operation capacity of urban sewage treatment systems.

1. What is a comprehensive pumping station? The design idea of integrated pumping station is to make the water source get enough potential energy from the pump, thus greatly improving the efficiency of sewage treatment. This kind of pumping station has been used in China for ten years, and its technical application has reached a quite mature level.

Invest time and funds in continuous research and development, improve the technical content of integrated pumping stations and the overall operating efficiency of the system, improve the urban sewage treatment capacity to a new level, and provide a clean water environment for urban residents and ecological environment.

Second, the application principle of integrated pumping station The application principle of integrated pumping station is that sewage (waste water) from cities or factories is sent to treatment equipment, solid impurities contained in sewage (waste water) are crushed into fine particles through the high-speed rotating grating inside the integrated pumping station, and then the impurities are taken out from the water outlet at the bottom of the integrated pumping station to prevent impurities from depositing and accumulating at the bottom of the integrated pumping station, which can effectively prevent the integrated pumping station from being blocked and affect the sewage (waste water) treatment effect.

When the pressure value of tap water P 1 is lower than the pressure value P2 set by the integrated pumping station, the microcomputer of the integrated pumping station will automatically control the variable frequency pump to run at a stable speed. The lower the pressure value of tap water P 1, the higher the speed of variable frequency pump in comprehensive pumping station, so as to achieve enough kinetic energy to treat sewage (wastewater).

The integrated pumping station has the advantages of light weight, low cost, large volume, good fluidity, self-cleaning function and no blockage. Its service life is more than twice that of other sewage treatment equipment, and it can be used for more than 30 years with reasonable maintenance. It is suitable for urban drainage, flood control and emergency rescue, sewage treatment and other places where it is impossible to discharge (waste) water by itself.

Third, considering the design of the comprehensive pumping station 1, the layout planning needs to be scientific and reasonable, and attention should be paid to the combination of drainage and irrigation, automatic drainage and water lifting, so as to achieve the integrated design of the gate and station system, improve the compactness of the structure and reduce the land occupation.

2. The integrated design of pumping station should ensure sufficient lift, and the pump selection should be carried out according to the design to ensure the sewage discharge requirements; If the cost conditions permit, the newer the pump components, the better, and the pump type with mature technology can be selected; In the trial operation stage, the pump type can be used, and the overall principle is to ensure the efficient operation of the system.

3. Designers should determine the pump model according to the actual situation of urban sewage and the application target of comprehensive pumping station.

4. It is best to design an integrated pumping station in the form of front water intake, so that all pumps can fully and symmetrically feed water; If the site condition cannot be positive, it must be horizontal; It is necessary to extend the distance between the water pump and the water inlet as much as possible to ensure smooth diversion.

5. When designing the outlet of the integrated pumping station, it is necessary to avoid sharp turns as much as possible to prevent the super impact force caused by high backwater and too fast water flow from damaging the system function.

Fourth, summarize the importance of water resources to people, whether it is life or production. At present, sewage treatment has become one of the important issues of widespread concern in society. Therefore, in order to further improve the effect and efficiency of urban sewage treatment, the most critical thing is to rationally optimize and improve the urban sewage treatment system.
