Problems solved by technology

[0004] Because the lifting pump room and the water distribution well occupy a large area, the construction cost of the pump room in practical application is high; and because the check valve or flap valve at the water pump outlet is often broken, which seriously affects the operation of the sewage treatment plant. Normal operation, and the resistance of the check valve or flapper is relatively large, which indirectly increases the lifting head of the sewage in daily use, resulting in high daily maintenance costs

Embodiment

[0029] Such as Figure 1 to Figure 4 As shown, the intensive pump house with lifting and water distribution functions is used to lift the sewage treated by the secondary settling tank, including the water inlet area 1 connected to the water inlet pipe 8, and the sewage is obtained from the water inlet pipe 8, and the water outlet pipe 9 Connect, and discharge the water outlet area 3 of sewage by means of outlet pipe 9;

[0030] The water outlet area 3 is set directly above the water inlet area 1; the side of the water outlet area 3 and the water inlet area 1 is provided with a lifting area 2;

[0031] Several submersible lift pumps at the bottom of some water pump wells 21 at the lower part of the lifting area 2 pump the sewage in the water inlet area 1 to the lifting area 2, and raise the water level of the sewage in the lifting area 2, so that the sewage overflows to the water outlet area 3;

[0032] The water inlet of each submersible lift pump is connected with the water ...

Abstract

The invention discloses an intensive pump house with lifting and water distributing functions. The intensive pump house with the lifting and water distributing functions comprises a water inlet area and a water outlet area; the water outlet area is arranged over the water inlet area; a lifting area is arranged on the side faces of the water outlet area and the water inlet area; sewage in the waterinlet area is pumped to the lifting area through a plurality of submersible lifting pumps arranged at the bottoms of a plurality of water pump wells located on the lower portion of the lifting area,the water level of the sewage is lifted in the lifting area, and the sewage overflows to the water outlet area; a water inlet of each submersible lifting pump communicates with a water pump water inlet canal located under the lifting area, and then the sewage in the water pump water inlet canal is lifted to the lifting area; one end of the water pump water inlet canal is connected with the bottomof the water inlet area, and the other end of the water pump water inlet canal is connected with the bottom of the lifting area; and the portion, close to the upper end, of the lifting area communicates with the portion, close to the upper end, of the water outlet area, and a water pump water outlet weir is formed by the side wall shared by the lifting area and the water outlet area. According tothe intensive pump house with the lifting and water distributing functions, the sewage lifting pump house behind a secondary sedimentation tank is improved, and on the premise that the lifting effectis guaranteed, the structure is simplified, and the building and maintaining cost is reduced.

Description

technical field [0001] The invention relates to the technical field of sewage transportation, in particular to an intensive pump house with lifting and water distribution functions. Background technique [0002] In existing sewage treatment plants, in order to avoid excessive burial of sewage treatment structures, it is usually necessary to set up a lifting pump room behind the secondary settling tank to lift the sewage treated by the secondary settling tank before entering the subsequent advanced treatment structures. [0003] In the prior art, the lifting pump room is generally provided with a water inlet area, a water pump lifting area, and a water outlet area according to the direction of water flow, and the water pump outlet of the water pump lifting area is generally provided with a check valve or a flap valve, which is used for pump maintenance. In order to ensure the uniformity of water inflow to the subsequent advanced treatment structures, it is necessary to set up...
