Do you know the general rules of the sewage pumping station?

The sewage pumping station is an important part of the sewage system, which is characterized by continuous flow, small water flow, but the change range is big. Therefore, the design of the sump to have enough storage capacity, and should be considered in addition to the design of the standby pump to reduce the pollution of the environment, the station to provide better conditions, maintenance management. In this article, the small series will introduce the general provisions of the sewage pumping station, as follows:
Self-priming sewage pump
General provisions:
1) should be based on the amount of sewage in the near future, to determine the scale of sewage pump station. The design flow rate of the pump station should be the same as the design flow of the water inlet pipe;
2) it should be clear whether the pumping station was built, or phased, is a permanent or semi permanent, in order to determine its standards and facilities. According to the sewage pumping station rises, people water canals, or into the treatment plant to select the suitable position of pumping station;
3) in the drainage system, rainwater pumping station and sewage pumping station can be divided into different built in pumping station in the hospital, also can build structures in a seat, but water pump, tank and piping should be set as a system;
4) sump and machine between the sewage pumping station to build in the same structure, a water collecting tank and machine room should be separated by waterproof wall, leakage is not permitted, practice according to the structure design specification; sump and machine construction to maintain a certain distance from the construction, avoid the uneven settlement of the pool the circular machines use square;
5) pump station underground structures do not allow groundwater seepage, should be provided with a high water level p.5m of the waterproof measures, practices, see "water supply and drainage engineering design code} FS9 GBJ - $4};
6) pay attention to reduce the impact on the surrounding environment, combined with local conditions, the pumping station and residential houses and public buildings to maintain a certain distance, the hospital must strengthen the green, as far as possible the courtyard garden, built around the isolation zone.
