[0042] It should be noted that the specific type of motor 6 to be used is selected by relevant technicians familiar with the field, and the above motor 6 and the like are all existing technologies and will not be elaborated in this solution.

[0043] The working principle and use process of the present invention are as follows: first, the sewage that has undergone primary treatment such as filtration, sand settling, and neutralization flows into the sewage bucket 1 through the water inlet valve 27, and then the handle 5 is slid open to put the montmorillonite into the reaction chamber 2. After the sealing door 4 is closed, the motor 6 is operated, and the motor 6 drives one end of the rotating shaft 8 to rotate. At this time, the rotating rod 11 fixed at the other end of the rotating shaft 8 will follow the rotating shaft 8 to form an orbit, and the wastewater is stirred in an orbit. Because one end of the air pipe 12 is fixed to the inner wall of the reaction chamber 2, and the other end of the air pipe 12 is rotatably connected to the rotating shaft 8, and the first gear 18 is fixed to the circumferential surface of the gas delivery pipe 12, the fixed block 20 is fixed on the rotating shaft 8, and the linkage rod 22 is rotatably connected to the inner wall of the fixed block 20, so when the rotating shaft 8 rotates, the first gear 18 is stationary, and the second gear 19 meshing with the first gear 18 will rotate, and the second gear 19 will drive the fourth gear 25 to rotate, then the third gear 24 meshing with the fourth gear 25 will rotate, and the third gear 24 will lead the rotating rod 11 to rotate, so that the rotating rod 11 will rotate while the orbiting When the motor 6 rotates, the stirring rod 13 fixedly connected to the output end of the motor 6 will rotate together, which will drive the stirring blade 15 to rotate, stirring the hydrogen peroxide and montmorillonite in the reaction chamber 2, and a large amount of oxygen will be generated. The oxygen will flow into the rotating shaft 8 along the gap between the gas pipe 12 and the stirring rod 13, and then flow from the rotating shaft 8 to the rotating rod 11. Finally, the oxygen in the rotating rod 11 will be sprayed into the sewage in the form of small bubbles through the multiple fine holes 17 on the nozzle 16, increasing the oxygen saturation in the wastewater treatment for oxygen supply to microorganisms, promoting It decomposes organic matter, helps mix wastewater and remove odor, improves treatment efficiency, and then the treated water is discharged through the outlet valve 26. Because industrial hydrogen peroxide is cheap and montmorillonite is a common mineral, the oxygen produced is a multi-point and multi-angle method of spraying small bubbles by revolution and rotation to further increase the oxygen saturation of sewage, thereby solving the traditional aeration process of wastewater treatment, which requires a lot of electricity to drive the blower or compressor to fill the wastewater with oxygen, which not only increases the operating cost, but also puts higher requirements on energy supply.

[0044] Example 2 Specific reference Fig.13On the basis of Example 1, a rotating drum 30 is rotatably sleeved between the gas transmission pipe 12 and the reaction chamber 2. The hollow part of the rotating drum 30 is fixed to the stirring rod 13. The outer circumference of the rotating drum 30 is fixedly connected to a scraper 28. The rotating drum 30 will rotate with the stirring rod 13, thereby driving the scraper 28 to rotate. The bottom of the scraper 28 is composed of two groups of crossed cross bars. The ends of the two groups of crossed cross bars are vertically provided with vertical bars fixed with scraper brushes 29. The scraper brushes 29 will repeatedly brush the inner wall of the sewage bucket 1 as the scraper 28 rotates to prevent excessive accumulation of sediments and affect the effect and efficiency of sewage treatment. A bottom scraper 31 is extended from the bottom of the two groups of crossed cross bars. The bottom scraper 31 is at a very low height from the reaction chamber 2 and is used to scrape off the sediment on the top of the reaction chamber 2. The height of the bottom scraper 31 from the reaction chamber 2 is very low, so as to more effectively prevent sludge deposition.
