[0002] In wastewater treatment, the role of aeration in sterilization is mainly reflected in achieving sterilization through aeration or gas injection. Common methods include ozone sterilization and aeration treatment.

[0003] In wastewater treatment, it is usually necessary to add bactericides to the wastewater for sterilization. However, existing bactericides are added to the wastewater all at once, resulting in a small contact area between the bactericide and the wastewater, which greatly reduces work efficiency. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an aeration and sterilization structure for wastewater treatment.

A drive assembly for rotating the second connecting pipe is provided on the outer wall of the top of the cylindrical body. Multiple stirring blades are fixedly connected to the outer side of the second connecting pipe. Multiple first connecting pipes are connected and fixedly connected to the outer side of the second connecting pipe. Multiple nozzles are connected and fixedly connected to the multiple first connecting pipes. An air guide pipe frame is fixedly connected to the inner wall of the bottom of the cylindrical body. A connection port is opened at the bottom of the cylindrical body, and the air inlet end of the air guide pipe frame passes through the connection port. Multiple aerators are connected and fixedly connected to the air guide pipe frame.

[0006] As a further embodiment of this utility model, the drive assembly includes a fixed frame, which is fixed to the top outer wall of the cylinder by bolts. A motor is fixedly connected to the upper surface of the fixed frame. One end of the motor output shaft passes through the fixed frame and is keyed to a second gear. The bottom end of the second connecting pipe passes through the cylinder and is keyed to a first gear, and the first gear meshes with the second gear.

[0007] As a further embodiment of this utility model, the top end of the second connecting pipe passes through the first gear and is fixed with a rotary joint, one end of the rotary joint is fixed with a guide pipe, and a valve is fixedly connected to the guide pipe.

[0008] As a further embodiment of this utility model, an air inlet pipe is fixedly connected to the connection port at the bottom of the cylinder, and the air inlet pipe is fixedly connected to the air inlet end of the air guide pipe frame.

[0009] As a further embodiment of this invention, the check valve assembly includes a check valve, which is installed on the second connecting pipe.

[0010] As a further embodiment of this invention, the multiple aerators are distributed at equal distances.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model not only enables the nozzle to spray the bactericidal liquid more evenly through the drive component, thereby improving the bactericidal effect and reducing the situation of incomplete sterilization in some areas due to uneven spraying, but also further sterilizes and disinfects the wastewater through the ozone released by the aerator at the bottom of the cylinder, thereby improving the sterilization efficiency.

[0012] 2. In this invention, the stirring plate rotates with the second connecting pipe, which makes the sterilizing solution and wastewater mix more thoroughly, helps the sterilizing solution to come into more comprehensive contact with the wastewater, thereby improving the sterilization effect and further enhancing the wastewater treatment quality.

[0017] Reference Figures 1-3A wastewater treatment ventilation and sterilization structure includes a cylinder 7. The top of the cylinder 7 is rotatably connected to a second connecting pipe 10 via a bearing. The second connecting pipe 10 is provided with a check valve assembly, which includes a check valve 15. The check valve is installed on the second connecting pipe 10 and the check valve assembly can prevent gas or liquid from flowing backward in the second connecting pipe 10. In particular, the top outer wall of the cylinder 7 is provided with a drive assembly for rotating the second connecting pipe 10. The drive assembly includes a fixed frame 5, which is fixed to the top outer wall of the cylinder 7 by bolts. A motor is fixed to the upper surface of the fixed frame 5 by bolts. One end of the motor output shaft passes through the fixed frame 5 and is keyed to a second gear 6. The bottom end of the second connecting pipe 10 passes through the cylinder 7 and is keyed to a first gear 1. The first gear 1 meshes with the second gear 6. The top end of the second connecting pipe 10 passes through the first gear 1 and is fixed with a rotary joint 2. One end of the rotary joint 2 is fixed with a guide pipe 3. The self-rotating design of the rotary joint 2 can prevent the guide pipe 3 from rotating with the second connecting pipe 10 when it rotates, so as not to affect the use of the guide pipe 3. A valve 4 is fixed on the guide pipe 3 by bolts, and the opening of the guide pipe 3 is controlled by the valve 4.

[0018] Multiple stirring blades 11 are fixed to the outside of the second connecting pipe 10 by bolts. Rotation of the second connecting pipe 10 causes the stirring blades 11 to rotate, making the disinfectant solution and wastewater more thoroughly mixed. Multiple first connecting pipes 8 are fixedly connected to the outside of the second connecting pipe 10, and multiple nozzles 9 are fixedly connected to each of the multiple first connecting pipes 8. Connect the guide pipe 3 to the external sterilization liquid supply equipment so that the sterilization liquid enters the second connecting pipe 10 through the guide pipe 3 and is sprayed onto the inner wall of the cylinder 7 through the nozzle 9 on the first connecting pipe 8. The rotation of the motor causes the second gear 6 to drive the first gear 1 to rotate, which in turn causes the second connecting pipe 10 to drive the nozzle 9 on the first connecting pipe 8 to rotate, so that the nozzle 9 can spray the bactericidal liquid more evenly. The bottom inner wall of the cylinder 7 is fixed with an air guide pipe frame 13 by bolts. A connection port is opened at the bottom of the cylinder 7, and the air inlet end of the air guide pipe frame 13 passes through the connection port. Multiple aerators 14 are connected and fixed on the air guide pipe frame 13. The model of the aerator 14 is DH65-500. An air inlet pipe 12 is fixedly connected to the connection port at the bottom of the cylinder 7, and the air inlet pipe 12 is fixedly connected to the air inlet end of the air guide pipe frame 13. Connect the air inlet pipe 12 to an external ozone supply device so that ozone enters the air guide pipe frame 13 through the air inlet pipe 12 and is discharged through the aerator 14. One side of the cylinder 7 is connected and fixed with an inlet pipe and an outlet pipe. Wastewater to be treated can be added into the cylinder 7 through the inlet pipe, and after treatment, the treated wastewater can be discharged through the outlet pipe.

[0019] Working principle: When it is necessary to aerate and sterilize the wastewater inside cylinder 7, First, a certain amount of wastewater to be treated is added into the cylinder 7 through the inlet pipe; Connect the air inlet pipe 12 to an external ozone supply device so that ozone enters the air guide pipe frame 13 through the air inlet pipe 12 and is discharged through the aerator 14. Use the strong oxidizing properties of ozone to sterilize and disinfect the wastewater. Connect the guide pipe 3 to the external sterilization liquid supply equipment so that the pre-calculated amount of sterilization liquid enters the second connecting pipe 10 through the guide pipe 3 and is sprayed out through the nozzle 9 on the first connecting pipe 8. The type and dosage of sterilization liquid can be selected and calculated according to the actual bacterial content in the wastewater. When the motor is started, the rotation of the motor causes the second gear 6 to drive the first gear 1 to rotate, which in turn causes the second connecting pipe 10 to drive the nozzle 9 on the first connecting pipe 8 to rotate, so that the nozzle 9 can spray the bactericidal liquid more evenly. At the same time, the rotation of the second connecting pipe 10 causes the stirring plate 11 to rotate, making the sterilization solution and wastewater more fully mixed and improving the sterilization effect; After stirring and aerating for a certain period of time, the wastewater inside cylinder 7 is sampled and tested. After the wastewater in cylinder 7 has passed the sterilization test, the sterilized wastewater in cylinder 7 is discharged, and then the next batch of wastewater to be treated is added into cylinder 7 through the liquid inlet pipe, and so on.
