The top of the stirring plate 16 is connected to a rotating shaft 8, and the top of the rotating shaft 8 is located on a fixed... Inside the fixed plate 9, a waterproof sealing cover 12 is provided above the fixed plate 9, and a drive motor 11 is provided at the middle of the top of the waterproof sealing cover 12; oxygen is delivered to the branch pipe 5 through the main pipe 4, oxygen is delivered to the aeration head 7 through the branch pipe 5, oxygen is aerated through the aeration head 7, and the balance support cover 20 is used to increase the stability of the installation of the mixing plate 16 and to support and position the mixing plate 16. The mixing plate 16 is used to stir the sludge around the aeration head 7 to prevent sludge sedimentation. The rotating shaft 8 is used to install and fix the mixing plate 16.

[0020] The two ends of the fixing plate 9 are connected to the wastewater treatment tank 2 through the limiting bracket 13. The fixing plate 9 and the limiting bracket 13 are connected by welding, and the limiting bracket 13 is fixedly connected to the wastewater treatment tank 2 by bolts. The limiting bracket 13 is used to limit and fix the installation position of the fixing plate 9.

[0021] The rotating shaft 8 is connected to the drive motor 11 via a transmission belt 10. The stirring plate 16 is connected to the rotating shaft 8 via an assembly sleeve 14, and the assembly sleeve 14 is fixedly connected to the rotating shaft 8 via a first fixing bolt 15. Multiple rotating shafts 8 can be driven to rotate simultaneously via the transmission belt 10, which makes better use of energy and saves costs.

[0022] Furthermore, the waterproof sealing cover 12 and the mixing plate 16 are connected to the positioning inlay 17 via the positioning inlay block 19, and the positioning inlay block 19 is set as a spherical structure, and the waterproof sealing cover 12 and the mixing plate 16 are both set as conical structures.

[0024] Working principle: During use, oxygen from the air is delivered to the connecting pipe 3 through the aerator 1, and then to the main pipe 4 through the connecting pipe 3. It is then delivered to each aeration head 7 through the branch pipe 5, dissolving the oxygen in the water. At the same time, the drive motor 11 converts electrical energy into mechanical energy, which drives multiple rotating shafts 8 to rotate at a constant speed through the transmission belt 10. This causes the mixing disc 16 to rotate. The rotation of the mixing disc 16 keeps the activated sludge in a suspended state in the wastewater treatment tank 2, increasing the uniformity of the mixture between the activated sludge and oxygen. This promotes bacterial growth and the metabolism of the activated sludge, thereby removing organic matter and pollutants such as nitrogen and phosphorus from the wastewater.
