[0022] Example 2

[0023] like Figures 2-4 As shown, the utility model proposes a continuous flow airlift aerobic granular sludge triple circulation wastewater treatment equipment. Compared with the first embodiment, the detailed structure of the blocking component is recorded in this embodiment. The blocking component includes a fixed ring 6, a connecting rod 7, a diverter plate 8 and an adjustment component. The fixed ring 6 is arranged in the wastewater treatment box 1. The fixed ring 6 has the same center as the wastewater treatment box 1. A plurality of connecting rods 7 are connected to the fixed ring 6. The connecting rods 7 are distributed around the circumference with the central axis of the wastewater treatment box 1 as the center. The connecting rods 7 are connected to the wastewater treatment box 1. There are multiple diverter plates 8 distributed around the circumference with the central axis of the fixed ring 6 as the center. The diverter plate 8 is a blocking end. A plurality of fixing rods are connected to the fixed ring 6. The diverter plate 8 is rotatably connected to the fixed rod bearings on the fixed ring 6. The adjustment component is connected to the fixed ring 6. When the adjustment component is in use, the moving end of the adjustment component moves along the central axis of the fixed ring 6 to adjust the angle between the diverter plate 8 and the water flow.

[0024] The adjustment assembly includes a moving ring 9, an adjusting rod 10, an adjusting frame 11 and a telescopic device 12. The moving ring 9 is arranged parallel to the fixed ring 6, and the moving ring 9 is sleeved on the outside of the diverter plate 8. The number of adjusting rods 10 corresponds to the diverter plate 8. The adjusting rods 10 are connected to the moving ring 9. The number of adjusting frames 11 corresponds to the diverter plate 8. The adjusting frames 11 are connected to the adjusting rods 10 and are arranged on the outside of the diverter plate 8. Two telescopic devices 12 are provided. The telescopic devices 12 are rotatably connected to the fixed ring 6, and the telescopic end of the telescopic device 12 is rotatably connected to the moving ring 9. The telescopic device 12 is selected from but not limited to a hydraulic cylinder.

[0025] In an optional embodiment, the adjustment frame 11 is composed of a U-shaped frame 13 and rollers 14. The U-shaped frame 13 is sleeved on the outside of the diverter plate 8, and a plurality of rollers 14 are rotatably connected to the U-shaped frame 13; the rollers 14 reduce the mutual friction between the U-shaped frame 13 and the diverter plate 8 when the two are in contact.

[0026] In an optional embodiment, a plurality of protrusions are connected to any side of the diverter plate 8; the protrusions will cause obstructions when contacting the water flow to increase the generation of vortices and turbulence.

[0027] Example 3

[0028] like Figures 1-2 As shown, the utility model proposes a continuous flow airlift aerobic granular sludge triple circulation wastewater treatment equipment. Compared with the second embodiment, the present embodiment records the detailed structure of the circulation component, which includes a reflux pump 15, a reflux pipe 16 and a guide cover 17. The reflux pump 15 is connected to the wastewater treatment tank 1. The water inlet and outlet ends of the reflux pump 15 are both provided with a reflux pipe 16. The reflux pump 15 is the power end. Both the two reflux pipes 16 are connected to the wastewater treatment tank 1. The guide cover 17 is connected to the wastewater treatment tank 1. The guide cover 17 has the same center as the wastewater treatment tank 1. The cross-section of the guide cover 17 is conical, and its diameter decreases from bottom to top to guide the water flow.

[0029] In an optional embodiment, an observation window 18 is provided on the wastewater treatment tank 1 .

[0030] In summary, when the present invention is used, the water supply equipment or water pump of the working external equipment draws the wastewater from the water inlet pipe 2 into the wastewater treatment box 1. At the same time, the external air supply equipment is connected to the aeration plate 5 through the air pipe for aeration, so that the wastewater comes into contact with oxygen. The wastewater moves upward under the drive of the air flow. When the reflux pump 15 is started, the reflux pump 15 extracts the wastewater at the top and discharges it to the top of the aeration plate 5 through the reflux pipe 16 connected to the water outlet end. The contact area of ​​the wastewater is increased by direct contact with oxygen. At the same time, when the wastewater rises with the gas, it will come into contact with the diverter plate 8. The diverter plate 8 itself has an inclination angle so that it generates shear force when it comes into contact with the vertically flowing water flow to promote the production of aerobic sludge particles. The protrusions connected to the diverter plate 8 will increase vortexes and turbulence to increase the friction and collision between the water flow and the sludge particles. The inclination angle of the diverter plate 8 can be adjusted to obtain different sizes according to different needs. The shear force of the telescopic end of the telescopic device 12 is extended, which drives the moving ring 9 to rotate with the central axis of the fixed ring 6 as the center. At this time, the adjusting rod 10 and the adjusting frame 11 connected to the moving ring 9 move synchronously, and the adjusting frame 11 pushes the diverter plate 8 to rotate with its rotating connection as the center to adjust the angle between the diverter plate 8 and the water flow. The rising water flow is gradually collected by the deflector 17 and enters the deflector 17. The inclined surface and the inner wall of the wastewater treatment tank 1 form a sedimentation area. If the reflux pump 15 stops running, aerobic granular sludge can be settled here. If the reflux pump 15 continues to run, aerobic granular sludge is extracted from here and continues to circulate. The sludge and wastewater can be discharged separately through the sewage pipe 3 and the outlet pipe 4 connected to the inner wall of the wastewater treatment tank 1. The gas generated by the wastewater reaction can be discharged through the exhaust pipe of the wastewater treatment tank 1. The staff can observe the current sludge morphology through the observation window 18 to adjust the parameters.

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
