[0039] The stirring frame 36 and the first water inlet pipe 14 are staggered, so that the stirring frame 36 will not collide with the first water inlet pipe 14 during rotation.

[0040] The method of using the intensive aerobic water treatment equipment of this application is as follows:

[0041] (1) Before use, the sewage is firstly put into the interior of the water inlet cylinder 20 through the second filter 21, and finally enters the interior of the biochemical reaction tank 3. During the sewage extraction process, the sewage inlet speed is controlled, and the motor 25 is started and operated at a low speed to avoid the sewage splashing due to excessive speed. The overflowing water flows into the interior of the impurity collection cylinder 22 and re-enters the interior of the biochemical reaction tank 3 through the reflux hole 23. In the design process, the second filter 21 can be designed to be concave, and the cleaning plate 33 and the cleaning brush 34 are made of silicone material;

[0042] (2) When in use, the untreated sewage is filtered through the second filter 21, and the large particles of impurities are screened out and enter the interior of the impurity collection cylinder 22. The staff promptly cleans the impurities inside the impurity collection cylinder 22, and then puts the medicine into the biochemical reaction tank 3 through the second water pipe 6 to react chemically with the sewage in the biochemical reaction tank 3. The treated sewage is filtered again through the first filter 11;

[0043] (3) Start the first water pump 12, and the sewage flows into the aerobic reaction tank 2 through the first water inlet pipe 14. At this time, open the aeration device 10 to allow air to fully contact the sewage and dissolve oxygen in the water to increase the dissolved oxygen concentration, thereby achieving the purpose of removing iron and manganese or promoting the degradation of organic matter by aerobic microorganisms;

[0044] (4) Subsequently, the second water pump 13 is started to pump the treated sewage into the disinfection tank 1, and a disinfectant (existing technology) is added into the disinfection tank 1 through the third control valve 9 for disinfection and sterilization;

[0045] (5) Finally, the first control valve 5 is opened to pump the resulting reclaimed water out of the disinfection tank 1 for use;

[0046] (6) When sewage enters the biochemical reaction tank 3, the motor 25 is started, and the motor 25 drives the adjustment plate 26 to rotate. The adjustment plate 26 drives the adjustment frame 28 to move left and right through the adjustment block 27, so that the adjustment frame 28 drives the rack 29 to move left and right, driving the first gear 31 to rotate forward and reverse, thereby driving the rotating shaft 30 to rotate forward and reverse, and the water inlet cylinder 20 drives the cleaning plate 33 to rotate forward and reverse, and the cleaning brush 34 under the cleaning plate 33 cleans impurities on the second filter 21;

[0047] (7) At the same time, the rotating shaft 30 drives the second gear 32 to rotate forward and reverse, and the second gear 32 drives the stirring frame 36 to move back and forth through the large gear 35. The stirring blades 37 on the stirring frame 36 stir the sewage to improve the reaction efficiency.

[0048] The electrical components appearing in this article are all electrically connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of this disclosure omits the detailed description of known functions and known components (for example, aeration devices).
