1, the sewage pumping station is set in the sewage pipe system, used to pump up the city sewage pumping station. The function is to raise the height of the sewage, because the sewage pipe is not like the water supply pipe (tap water), and it has no pressure and gravity self flow of the sewage itself. Because the urban sewage interception network management area has a wide area of sewage and is far away from the sewage treatment plant. It is impossible to bury the pipe very deep, so it is necessary to set up the pumping station to elevate the height of the sewage.

2. It is a pumping station set up in the sewage treatment plant to improve the sewage. The function is to provide the flow power for the subsequent process. Generally speaking, the height of the sewage lifting is the height of the tail water discharged from the sewage treatment, and the head loss is subtracted and calculated by backward push. Health level self-priming pump

The design of the sewage pumping station mainly includes:

1, the selection of the pump;

2. Determine the volume and size of the pool.

3. Calculation of water pipe outlet pipe;

4, the layout of the pump house;

5, the building form of the pump house;

6. The selection and arrangement of lifting equipment;

7, the design of electrical equipment and automatic control equipment;

8. The design of the building, electric and structure of the pump house;

9. The determination of the construction method. The general provisions of the sewage pumping station will be discussed below.

1, the scale of the sewage pump station should be determined according to the far and near sewage quantity, and the design flow of the sewage pumping station is the same as the design flow of the inlet pipe.

2, it should be clear whether the sewage pump station is built or built in stages, which is permanent or semi permanent to determine its standards and facilities. According to the sewage pumping station upgrade after the water into the canals or into the treatment plant to the selected location of sewage pumping station.

In 3, drainage system, rainwater pumping station and sewage pumping station can be built in different positions in the hospital, also can build structures in a seat, but the sewage lifting pump, sump and pipeline should be self system.

Sump and machine 4, a sewage pumping station in same building, collecting tank and machine room with waterproof leakage is not permitted, separated by a partition, practice according to the structure design specification; sub built pool and machine to maintain a certain distance between the construction, in order to avoid the uneven settlement of the tank is set round, square multiple machines.

5. The structure of the pumping station is not allowed to infiltrate the ground water, and the waterproof measure of 0.5m of the groundwater level should be set up.

6, pay attention to reduce the impact on the surrounding environment. Combined with the local conditions, make the pumping station and residential buildings and other public buildings to maintain a certain distance. The pumping station must be greening in the hospital and build a partition wall in 4 weeks.
