Characteristics and regulations of sewage pumping station

Characteristics and regulations of sewage pumping station
(1) Features: Sewage pumping station is characterized by continuous water, water is small, but the change is large; the amount of debris in water, the impact of the surrounding environment pollution. So the sewage pumping station should be used for sewage pumps and cleaning capacity of the grille decontamination machine, the pool should have enough capacity storage capacity, the pump running for a long time, should consider the standby pump; pump design should be minimized Environmental pollution, the station to provide better management, maintenance conditions.
(2) General provisions:
1) should be based on far and near the amount of sewage to determine the size of sewage pumping stations. Pump station design flow should be the same as the design flow of the inlet pipe.
2) should be clear whether the pump station is built, or in phases, is permanent or semi-permanent, to determine its standards and facilities. And according to the sewage pumping through the pumping station, the water canal, or into the treatment plant to select the appropriate pump station location.
3) In the shunt drainage system, the rainwater pumping station and the sewage pump house can be built in different positions in the pumping station, but also can be built in a structure, but the water pump, the pool and the pipeline should be self-contained
4) When the sump and the machine of the sewage pumping station are to be built in the same structure, the water collecting pool and the machine shall be separated by a waterproof partition, and the leakage shall not be allowed. According to the structural design specification, the water collecting pool and the machine To maintain a certain construction distance, to avoid uneven settlement, which collectively use a circular pool, the machine between the use of square.
5) The underground structure of the pumping station does not allow the infiltration of groundwater, should be set up more than the groundwater level p.5m waterproof measures, see the "water supply and drainage engineering structural design specifications}} GBJ fs9 - $ 4}.
6) pay attention to reduce the impact on the surrounding environment, combined with local conditions, so that the pump station and residential housing and public buildings to maintain a certain distance, the hospital must strengthen the green, as far as possible garden garden, surrounded by isolation.
