Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0011] exist figure 1 In, is the structure schematic diagram of this device, which is a kind of sewage treatment lifting pump station, which consists of sewage pipe (1), water inlet pipe (2), lift check valve (3), pipe 1 (4), filter guide Flow device (5), water outlet pipe (6), backwash pipe (7), submersible pump (8) and water tank (9), in which filter diversion device (5), water outlet pipe (6), backwash pipe ( 7) and submersible pump (8) in the water tank (9). The sewage enters from the pipe 1 (4), flows through the lifting check valve (3), the water inlet pipe (2), enters the filter diversion device (5) from the water inlet (5-3), and the filter screen (5-1 ) for solid-liquid separation of sewage, solids and impurities are blocked and deposited at the bottom of the filter diversion device (5), and the filtered sewage is discharged into the water ta...

Abstract

The invention discloses a lift pump station for sewage treatment. The lift pump station is mainly used for lifting sewage. In the device, a filtering and flow guiding device firstly filters the domestic sewage for solid-liquid separation, and it is avoided that because the domestic sewage directly flows through a pump, solid impurities in the sewage block the pump, and the pump can not operate normally. Solids and the impurities after filtering are precipitated at the bottom of the filtering and flow guiding device, the filtered sewage enters a water tank, and when the sewage in the water tank reaches a certain height, submerged type sewage pumps are started. At the moment, the sewage enters the filtering and flow guiding device again to clean a filter net in an all-around mode. The solids and impurities which are filtered and precipitated before are discharged from the pump station together with the sewage. Flow-guiding plates enable the sewage to clean the filter net in the more all-around mode, the filter net can not be blocked, and resistance of pipelines is reduced. The discharged sewage is prevented from flowing back to the water inlet pipeline to the maximum degree due to two non-return devices, and therefore the lift pump station can be safer. An even-mixing nozzle in a water outlet is used for flushing precipitates in the water tank, and then the precipitates are discharged through the pump.

Description

technical field [0001] The invention relates to a sewage treatment lifting pump station, which belongs to the field of environmental protection. Background technique [0002] The crisis of water resources has become the focus of global attention. Cherishing water conservation and recycling water resources have become a common consensus. In the process of water recycling, filtration is a commonly used technology for water treatment. Because some sewage filters are easy to cause debris to block the filter screen, the backwashing device is relatively complicated, and backwashing needs to consume a lot of clean water and electric energy. Contents of the invention [0003] The content of the present invention is: to overcome the above-mentioned deficiencies, to invent a sewage treatment lifting pump that does not need to use new cleaning water, but filters on the basis of sewage, cleans the filter net with filtered water, and lifts sewage to a high place stand. [0004] The t...
