Technical Field

[0001] The utility model relates to the technical field of aeration tanks, and more specifically, to an aeration tank for sewage treatment. Background Art

[0002] Wastewater treatment is the process of purifying sewage so that it meets the water quality requirements for discharge into a water body or reuse.

[0003] The process of sewage treatment usually includes multiple steps, one of which is aeration treatment in an aeration tank. In this process, flowing air is introduced into the sewage to stir the sewage, so that the gravel in the sewage will collide with each other, and the organic matter attached to the gravel will enter the sewage, which is convenient for the subsequent process of sewage treatment. However, the existing aeration tank usually only has a few air pipes connected to the sewage in the aeration tank. In this process, the sewage will gradually enter and exit the aeration tank. Some of the sewage is too far away from the air outlet of the air pipe and cannot be pushed by the flowing air, resulting in insufficient aeration effect. Therefore, a structure is set to solve the problem of insufficient aeration treatment effect in some existing aeration tanks.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an aeration tank for sewage treatment.

[0007] The utility model is further configured as follows: a plurality of flow guide members are distributed in an array along the flow direction of sewage.

[0008] The utility model is further configured as follows: the width of the guide piece is consistent with the inner width of the pool body and the top surface is flush with the top surface of the pool body, and a guide groove connected to the aeration cavity is arranged between the bottom of the guide piece and the inner bottom surface of the pool body.

[0009] The utility model is further configured as follows: a placement groove is provided at the bottom of the flow guide, a first air guide pipe is fixedly connected in the placement groove, and an air outlet slot is provided directly below the first air guide pipe.

[0010] The utility model is further configured as follows: the air guide and outlet portion comprises a symmetrically arranged air guide member with a hollow interior, the air guide member is fixedly connected to a plurality of second air guide pipes distributed in an array, and the second air guide pipes are provided with a plurality of air outlet holes distributed in an array along the length direction thereof.

[0011] The utility model is further configured as follows: a plurality of the second air guide tubes are configured as two rows distributed vertically, the two rows of the second air guide tubes correspond to each other one by one and the openings of the air outlets are opposite to each other.

[0012] The utility model is further configured as follows: a guide plate sleeved on the second air guide pipe is provided between two adjacent guide members.

[0013] In summary, the utility model has the following beneficial effects:

[0014] Under the action of the guide member, the sewage can be stably guided into the aeration cavity, so that the sewage can come into contact with the flowing air guided by the air outlet portion in the aeration cavity, so that the air can better come into contact with the sewage, thereby ensuring a better effect of sewage aeration treatment.

[0021] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] The sewage treatment aeration tank, such as Figure 1-Figure 3As shown, it includes a pool body 1 with a top opening, and an air guide outlet portion is fixedly connected to the inner bottom surface of the pool body 1, and the air guide outlet portion is used to achieve stable guidance of the flowing air. An aeration cavity 2 connected to the air outlet end of the air guide outlet portion is arranged between the air guide outlet portion and the pool body 1, and the formed aeration cavity 2 is used to provide a stable space for the aeration process, and a plurality of guide members 3 for guiding sewage to flow through the aeration cavity 2 are arranged in the pool body 1. Under the action of the guide members 3, the sewage can be stably guided into the aeration cavity 2, and then the sewage is in contact with the flowing air guided by the air guide outlet portion in the aeration cavity 2, so that the flowing air can better contact with the sewage, thereby ensuring a better effect of sewage aeration treatment.

[0023] like Figure 2-Figure 5 As shown, a plurality of guide members 3 are arranged in an array along the flow direction of sewage, the width of the guide member 3 is consistent with the inner width of the tank body 1 and the top surface is flush with the top surface of the tank body 1. This arrangement ensures that the guide member 3 can achieve stable blocking of the sewage flow process in the tank body 1, and a guide groove 4 connected to the aeration cavity 2 is arranged between the bottom of the guide member 3 and the inner bottom surface of the tank body 1. The guide groove 4 formed by the guide member 3 allows the sewage to pass over the guide member 3 with the help of the guide groove 4. In this process, the sewage will better enter the aeration cavity 2 and be pushed by the air flowing in the aeration cavity 2, thereby achieving stable aeration treatment of the sewage.

[0024] like Figure 2-Figure 5 As shown, a placement groove 5 is provided at the bottom of the guide member 3, and a first air guide pipe 6 is fixedly connected in the placement groove 5. An air outlet slit 7 is provided directly below the first air guide pipe 6. The placement groove 5 is provided to achieve stable placement and storage of the first air guide pipe 6, reduce the space occupied by the first air guide pipe 6 for the guide groove 4, so that the sewage can better pass over the guide member 3 with the help of the guide groove 4, and the first air guide pipe 6 is connected with the air source. Under the guidance of the first air guide pipe 6, the flowing air will be discharged through the air outlet slit 7, and the flowing air discharged from the air outlet slit 7 will come into contact with the sewage, thereby achieving stable impact on the sewage flowing through the guide groove 4 and realizing aeration treatment of the sewage.

[0025] like Figure 2-Figure 5As shown, the air guide outlet portion includes a symmetrically arranged air guide member 8 with a hollow interior, the air guide member 8 located on one side is connected to an air source, and a plurality of second air guide pipes 9 distributed in an array are fixedly connected to the air guide member 8 by welding, the second air guide pipe 9 is connected to the air guide member 8, and the flowing air generated by the air source will enter the air guide member 8, and under the guidance of the air guide member 8, the flowing air enters the second air guide pipe 9 connected to it, and the second air guide pipe 9 is provided with a plurality of air outlet holes 1 distributed in an array along its length direction. 0, the air flowing in the second air duct 9 flows out through the air outlet 10 and contacts the sewage to achieve agitation and aeration treatment of the sewage. The second air ducts 9 are arranged in two rows distributed up and down, and the two rows of second air ducts 9 correspond to each other and the openings of the air outlet 10 are opposite. This arrangement ensures that the flowing air flowing out of the air outlets 10 in different rows are in opposite directions, and the sewage is pushed to flow and collide with each other by the flowing air, so that the mixing of the sewage and the collision of solid impurities in the sewage are more sufficient, so that the aeration treatment effect of the sewage is better.

[0026] like Figure 2-Figure 5 As shown, a guide plate 11 sleeved on the second air guide pipe 9 is provided between two adjacent guide members 3, the bottom surface of the guide plate 11 is in contact with the inner bottom surface of the pool body 1, and the side wall of the guide plate 11 is in contact with the inner wall of the pool body 1. Under the action of the guide plate 11, the sewage flowing to the guide plate 11 will flow upward along the guide plate 11, and then will flow better along the side close to the air outlet slit 7, so that the flowing air can better aerate the sewage.
