Plate 8 is used to drive the sewage in the aeration tank 1 to circulate, so that the sewage at both ends of the aeration tank 1 can be transferred back and forth, so that the sewage to be treated continuously refreshes the gas-liquid contact surface to increase the oxygen absorption and improve the sewage treatment efficiency. A second motor 9 is bolted to one side of the outer wall of the aeration tank 1. The output shaft of the second motor 9 is connected to a rotating rod 10, and the rotating rod 10 passes through the inner walls of both ends of the aeration tank 1 through bearings. A shovel cage 11 is fitted on the outer wall of the rotating rod 10. The shovel cage 11 is rotatably connected to the aeration tank 1 through the rotating rod 10 and the output shaft of the second motor 9. An opening 12 is opened on the outer wall of the shovel cage 11, and the opening 12 is symmetrically arranged about the central axis of the shovel cage 11. The opening 12 facilitates the sludge to enter the shovel cage 11 through the rotation of the shovel cage 11, and completes the turning of the activated sludge at the bottom of the aeration tank 1, so that the activated sludge can better exert its decontamination effect.

[0021] Please see Figure 1 and Figure 4A wastewater circulation aeration device includes: an inlet pipe 13 connected to one outer wall of an aeration tank 1; a telescopic hose 14 connected to the other end of the inlet pipe 13; an elbow 15 fitted in the middle of the telescopic hose 14; and a conveying pipe 16 connected to the end of the telescopic hose 14 away from the inlet pipe 13. The conveying pipe 16 is connected to the inlet pipe 13 via the telescopic hose 14 and the elbow 15, and the conveying pipe 16 is telescopically connected to the inlet pipe 13 via the telescopic hose 14. The conveying pipe 16 is used to feed wastewater through the inlet pipe 13 and the telescopic hose 14. Various materials required for wastewater treatment are placed in the conveying pipe 16, and the conveying pipe 16 is placed in a suitable position by adjusting the extension of the flexible hose 14 and the bend, so as to facilitate the stable and uniform delivery of materials. The upper outer wall of the conveying pipe 16 is provided with a conveying hole 17, and the conveying hole 17 is evenly distributed at equal intervals along the upper surface of the conveying pipe 16. The conveying hole 17 is used to uniformly input the various forms of materials conveyed from the conveying pipe 16 into the bottom of the aeration tank 1, so that the material input is more uniform and the input material directly enters the sludge or other wastewater treatment materials at the bottom of the aeration tank 1.

[0022] Working Principle: For this type of wastewater circulation aeration equipment, the operator first places the aeration tank 1 on a stable, level working surface in the working environment. Then, the wastewater to be treated is input into the aeration tank 1. The aeration tank 1 is equipped with a shovel cage 11 for stirring and turning the activated sludge, and a sleeve 7 and push plate 8 for driving the wastewater circulation. When the wastewater treatment operation begins, the first motor 3 installed on one side of the platform 2 drives the roller shaft 4 to rotate through the output shaft. The roller shafts 4 rotate synchronously through the shaft head 5 and the transmission belt 6. When the roller shaft 4 rotates, it drives the sleeve 7 and the push plate 8 fixed on it to rotate, thereby causing the wastewater at one end of the aeration tank 1 to flow to the other end, refreshing the gas-liquid contact surface of the wastewater, increasing the oxygen absorption of the active substances in the wastewater, and improving the treatment efficiency. The water treatment efficiency is improved. At the same time, the sewage circulates at both ends of the aeration tank 1 through the rotation of the push plate 8 and the sleeve 7, increasing the contact time between the sewage and the activated sludge at both ends. Then, the shovel cage 11 rotates at both ends of the aeration tank 1 under the drive of the second motor 9 and the rotating rod 10. The shovel cage 11 shovels and turns the activated sludge through the opening 12, so that the deposited activated sludge can be turned to the upper layer for degradation. Finally, if it is necessary to add materials to the aeration tank 1, they can be pumped or smoothly input through the feed pipe 13 and the telescopic hose 14. The materials of various forms are adjusted by the extension and rotation of the telescopic hose 14 and the bend, so that the conveying pipe 16 can stably and evenly transport the materials to the required position through the conveying hole 17, improving the feeding efficiency and stability.
