Description

Technical Field

[0001] This utility model relates to the field of suspended biological packing technology, and in particular to a suspended biological packing device. Background Technology

[0002] Suspended biological packing material refers to spherical suspended packing material, also known as porous rotating spherical suspended packing material. It is the latest series of products developed from various packing materials used in domestic wastewater treatment and biofilm treatment technologies. In the biological treatment of wastewater, it has a fully three-dimensional structure, a large specific surface area, can be directly added without fixing, is easy to form a biofilm, and does not clog.

[0003] Traditional suspended media (such as polyethylene balls) often suffer from uneven aeration and improper tank design, leading to media accumulation or uneven fluidization. Especially at the outlet, due to water flow, suspended biological media tend to accumulate, affecting the effluent rate and causing uneven distribution of suspended biological media within the reaction tank, which can negatively impact wastewater treatment.

[0004] A wastewater treatment packing device is designed, which is suitable for traditional moving bed or fixed bed biofilm reactor processes. Utility Model Content

The motor is fixed at the rear of the pool body; One end of the rotating shaft is connected to the output end of the motor, and the other end is sleeved on the shaft sleeve; The rotating drum is sleeved outside the rotating shaft, and both ends of the rotating drum are connected to the rotating shaft by multiple connecting rods; The pusher plate consists of multiple pieces, some of which are located inside the pool and close to the outlet pipe; each pusher plate is evenly connected to the rotating drum along the tangential direction of the drum; the pusher plate has multiple mesh holes.

[0006] Specifically, the surface of the push plate is smooth.

[0007] Specifically, the openings of the two rows of branch pipes near the bottom of the pool are inclined downwards, and the opening angle of the air outlet is inclined downwards at 45° to 60°.

[0008] Specifically, the motor is configured as a variable frequency motor.

[0009] Specifically, the angle between two adjacent rows of branch pipes is between 36° and 45°. The beneficial effects of this utility model are as follows: This invention uses a pusher plate to move the suspended biological packing material away from the outlet, allowing the suspended biological packing material to be evenly distributed in the tank, thereby enabling sufficient aeration and achieving good sewage treatment results.

[0010] This invention, through the staggered arrangement of aeration pipes, can ensure that the suspended packing material is in a fluidized state, thereby improving the mass transfer efficiency between the biofilm and pollutants. Attached Figure Description

[0019] Preferred embodiments of this utility model will be described in detail with reference to the accompanying drawings, which will facilitate the implementation of these embodiments by those skilled in the art. However, this utility model can be implemented in various different forms, and therefore is not limited to the embodiments described below. Furthermore, for clarity, components not connected to this utility model will be omitted from the drawings.

[0020] A suspended biological packing device includes: a tank body 1, an inlet pipe 2, an outlet pipe 3, an aeration pipe 4, a bushing 5, a motor 6, a rotating shaft 7, a rotating drum 8, a connecting rod 9, and a push plate 10. like Figure 1-2As shown, one side of the pool body 1 is connected to an inlet pipe 2 and an aeration pipe 4, and the other side is connected to an outlet pipe 2; a fixing strip 11 is provided on the front wall of the pool body 1; suspended biological filler is placed in the pool body 1. The bushing 5 is fixed to the fixing strip 11; like Figure 3-5 As shown, multiple rows of branch pipes 41 are connected to the outer wall of the aeration pipe 4. Each row of branch pipes 41 is staggered and arranged radially to ensure that the bubbles are evenly distributed in the tank 1. The branch pipes 41 are provided with air outlets. like Figure 6-8 As shown, the motor 6 is fixed to the rear of the pool body 1; One end of the rotating shaft 7 is connected to the output end of the motor 6, and the other end is sleeved on the bushing 5; The rotating cylinder 8 is sleeved on the outside of the rotating shaft 7, and the two ends of the rotating cylinder 8 are connected to the rotating shaft 7 by multiple connecting rods 9; There are multiple push plates 10, some of which are located inside the tank body 1 and close to the outlet pipe 3. Each push plate 10 is evenly connected to the rotating cylinder 8 along the tangential direction of the rotating cylinder 8. The push plate 10 has multiple mesh holes 101. When the push plate 10 pushes the suspended biological filler, water flows out from the mesh holes 101 without affecting the water outflow rate. The push plate 10 is used to push the suspended biological filler away from the outlet, so that the suspended biological filler can be evenly distributed in the tank body 1, thereby enabling sufficient aeration.

[0021] Furthermore, the surface of the pusher plate 10 is smooth to prevent suspended biological filler from adhering to the pusher plate 10.

[0022] Furthermore, the openings of the two rows of branch pipes 41 near the bottom of the pool 1 are set to be inclined downwards, and the opening angle of the air outlet is inclined downwards at 45° to 60° to ensure that mud does not accumulate at the bottom of the pool 1.

[0023] Furthermore, the motor 6 is configured as a variable frequency motor, which controls the fluidization state of the packing through frequency conversion to ensure that the packing is far away from the outlet.

[0024] Furthermore, the angle between two adjacent rows of branch pipes 41 is between 36° and 45°.

[0025] In the description of this technical solution, it should be specifically noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" used herein should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a diametrical connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
