Description

Sedimentation and aeration integrated device

technical field

The utility model relates to an integrated sedimentation and aeration device, which belongs to the technical field of sewage treatment.

Background technique

In the existing aeration and sedimentation device, the aeration tank and the sedimentation tank are constructed separately, which has the following problems: the structure of the required sedimentation tank is complex, and equipment such as a mud scraper and a sludge return pump are needed to transfer the sedimentation tank The sludge is transferred to the aeration tank, and the investment cost and operation cost are relatively high.

Utility model content

The purpose of the utility model is to provide an integrated sedimentation and aeration device for the above-mentioned problems in the prior art, which can realize the automatic return of sludge, save the sludge return equipment, and has a simple structure and low cost.

In order to achieve the above object, the technical scheme of the utility model is as follows:

An integrated device for sedimentation and aeration, including a tank body, characterized in that the tank body is provided with a barrier that separates the tank body into an aeration area and a sedimentation area, and there is a gap between the barrier and the bottom of the pool ; The aeration area is provided with an aeration pipe connected to an external air source; the bottom of the sedimentation area has a slope extending toward the aeration area, and the upper part of the sedimentation area has a water outlet.

After repeated and sufficient aeration in the aeration zone, the sewage enters the sedimentation zone for sedimentation, and finally is discharged from the water outlet. The settled sludge flows into the aeration zone along the bottom slope of the sedimentation zone, thereby realizing automatic backflow.

The further perfect technical scheme of the utility model is as follows:

Preferably, the slope at the bottom of the sedimentation zone extends from the sidewall of the sedimentation zone to the bottom of the aeration zone.

Preferably, the barrier extends from the top of the pool body to the bottom of the pool.

Preferably, the aeration pipe has a number of aeration holes, and the aeration pipe is horizontally arranged at the lower part of the aeration area.

The utility model can realize automatic reflux of sludge, saves sludge reflux equipment, has simple structure and low cost.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is a schematic structural view of an embodiment of the utility model.

Detailed ways

Example

The sedimentation and aeration integrated device of this embodiment is shown in Fig. 1, comprises tank body 1, is provided with in the tank body 1 and divides tank body 1 into aeration area 3 and sedimentation area 4 partition member 2 (such as baffle plate , block, etc.), there is a gap between the barrier 2 and the bottom of the pool; the aeration tube 5 connected to the external air source is arranged in the aeration area 3; the bottom of the sedimentation area 4 has a slope extending toward the aeration area 3 4-1, there is a water outlet 6 in the upper part of the sedimentation zone 4 .

After repeated and sufficient aeration in the aeration zone 3, the sewage enters the sedimentation zone 4 for precipitation, and finally is discharged from the water outlet 6. The settled sludge flows into the aeration zone 3 along the slope 4-1 at the bottom of the sedimentation zone 4, thereby realizing automatic reflow.

Specifically, the slope 4-1 at the bottom of the sedimentation zone 4 extends from the side wall of the sedimentation zone 4 to the bottom of the aeration zone 3, which can further ensure that the sludge can flow into the aeration zone 3; The bottom extends, which can further simplify the structure and reduce the construction cost; the aeration tube 5 has a number of aeration holes 5-1, and the aeration tube 5 is horizontally arranged at the lower part of the aeration zone 3, which can make the aeration efficiency higher.

The device in this embodiment can realize the automatic sludge return, save the sludge return equipment, and has a simple structure and low cost.

In addition to the above embodiments, the utility model can also have other implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the utility model.
