Problems solved by technology

At present, the general prefabricated pumping stations on the market are only used for sewage lifting and discharge. This type of prefabricated pumping station is used in the process of lifting and discharging rural domestic sewage. When supporting small and medium-sized sewage treatment stations, due to the daily treatment The capacity is small, and the treatment time is long, and the discharge time of rural domestic sewage is relatively fixed and concentrated, so it will increase the treatment pressure of the sewage treatment station

Embodiment 1

[0023] Refer to attached Figure 1-2 , this embodiment provides a prefabricated pumping station capable of sewage pretreatment, including a pumping station main body 1 and a control cabinet 17, the two ends of the pumping station main body 1 are respectively provided with a water inlet 2 and a water outlet 3, and The top of the main body 1 of the pumping station is provided with a set of sight mirrors 21 and two sets of safety entrances 18. The setting of the sight mirrors 21 is convenient for observing the working state inside the main body of the pumping station 1. A safety grid 19 is detachably installed in the safety entrance 18. A ladder 22 can be provided below the safety entrance 18, and a manhole cover 20 is hinged above the safety grid 19. Through two groups of safety entrances 18, the inside of the pump station main body 1 can be entered, so as to facilitate maintenance of the equipment in the pump station main body 1.

[0024] In addition, the water outlet 3 communi...

Embodiment 2

[0030] Refer to attached image 3In order to prevent large-volume pollutants such as suspended solids from entering the membrane treatment area 7, this embodiment is improved on the basis of embodiment 1. Specifically, the sedimentation area 6 is provided with a barrier for intercepting dirt The dirt assembly, the water inlet 2 communicates with the sedimentation area 6 through the dirt block assembly. Wherein, the trash blocking assembly includes a basket grille 23 and a second guide rail 24, the basket grille 23 is slidably matched with the second guide rail 24, and the second guide rail 24 is installed above the water inlet 2 to facilitate Lift the basket grill 23 out for cleaning or maintenance. Through the setting of the basket grid 23, the suspended solids and large particle pollutants in the sewage can be intercepted to prevent large volume pollutants such as suspended solids from entering the membrane treatment area 7, thereby avoiding the adsorption of suspended soli...

Embodiment 1-2

[0031] In combination with Embodiment 1-2, the prefabricated pump station provided by the embodiment of the present invention, when in use, the sewage first flows in from the water inlet 2, and enters the sedimentation area 6 through the basket grid 23; then, the sewage continues to enter, When the water level in the sedimentation zone 6 was higher than the first dividing plate 4, the sewage could enter the membrane treatment zone 7; The sewage is purified; then, when the water level in the membrane treatment area 7 is higher than the second partition 5, the purified sewage can overflow from the second partition 5, and pass through the submersible pump 14 from the water outlet 3 discharge.

[0032] In summary, in the embodiment of the present invention, by setting the first partition 4 and the second partition 5 in the pump station main body 1, the precipitation zone 6 and the membrane treatment zone 7 can be formed in the pump station main body 1; in addition, the present inv...

Abstract

The invention discloses a prefabricated pumping station used for sewage pretreatment, and belongs to the field of sewage treatment. The prefabricated pumping station comprises a pumping station main body; the pumping station main body is provided with a water inlet and a water outlet; the water outlet is communicated with an immersible pump; a first separating plate and a second separating plate are arranged in the pumping station main body; a precipitation zone is formed between the first separating plate and the water inlet; a film processing zone is formed between the second separating plate and the first separating plate; the immersible pump is arranged between the second separating plate and the water outlet; a membrane assembly used for purifying sewage is arranged in the film processing zone. A plurality of groups of bio-membrane are arranged in the film processing zone, and an aeration pipe communicated with a blower is arranged below the bio-membrane, so that the aeration pipeand the bio-membrane are used for high efficiency purifying of sewage in the film processing zone, the content of pollutants in sewage discharged through the water outlet is reduced greatly, and sewage processing station processing burden is reduced.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a prefabricated pump station capable of performing sewage pretreatment. Background technique [0002] A pump station is a device and project that can provide hydraulic power and pneumatic power with a certain pressure and flow. At present, the general prefabricated pumping stations on the market are only used for sewage lifting and discharge. This type of prefabricated pumping station is used in the process of lifting and discharging rural domestic sewage. When supporting small and medium-sized sewage treatment stations, due to the daily treatment The capacity is small, and the treatment time is long, and the discharge time of rural domestic sewage is relatively fixed and concentrated, so it will increase the treatment pressure of the sewage treatment station. [0003] In this regard, there is an urgent need for a prefabricated pump station with sewage pretreatment function to ef...
