DETAILED DESCRIPTION

[0023] Referring to Figures 1-6As shown, the technical solution adopted in this specific embodiment is as follows: It includes a processing body 4, a protective reinforcing ring 6 is fixedly installed on the side of the processing body 4, an agitation component 2 and a water inlet pipe 3 are installed on the upper end of the processing body 4, and an air intake component 9 is installed on the lower end of the processing body 4. Both the agitation component 2 and the air intake component 9 penetrate the processing body 4. A water outlet pipe 1 and a sewage discharge pipe 7 are provided on the outside of the processing body 4. The agitation component 2 includes a stirring power motor 21, which is located at the upper end of the processing body 4. A stirring column 23 is mechanically connected to the output end of the stirring power motor 21, and stirring blades 22 are installed on the outside of the stirring column 23. The air intake component 9 includes an air intake pump 91, an air intake pipe 96 is provided at the air outlet of the air intake pump 91, a connecting chamber 93 is provided at the other end of the air intake pipe 96, a connecting pipe 94 is installed on the side of the connecting chamber 93, and an air bubble stone 92 is installed on the outside of the connecting pipe 94.

[0024] More specifically, several support columns 8 are installed below the protective reinforcement ring 6. The support columns 8 are capable of supporting and raising the equipment.

[0025] More specifically, an observation window 5 is installed on one side of the main processing unit 4. The observation window 5 allows staff to observe the internal condition of the device, thus facilitating timely maintenance and cleaning.

[0026] More specifically, the mixing blades 22 are provided in multiple layers on the mixing column 23, and the mixing blades 22 on the mixing column 23 are arranged with a shorter middle section and longer ends. The multiple mixing blades 22 can ensure the mixing efficiency, thereby increasing the aeration efficiency of the wastewater.

[0027] More specifically, each stirring blade 22 has a pointed end and a flat end in cross-section. The pointed end reduces the stirring resistance of the stirring blade 22, while the flat end can better agitate the wastewater, allowing for better contact between the air and the wastewater.

[0028] More specifically, the intake pipe 96 is equipped with a check valve 95 to prevent its wastewater from entering the intake pump 91.

[0029] More specifically, there are multiple air stones 92 and connecting pipes 94, and each air stone 92 is connected to the connecting chamber 93 through the connecting pipe 94. Multiple air stones 92 allow for a larger contact area between the air and the wastewater.

[0030] The working principle of this utility model is as follows: When treating sewage, the sewage enters the treatment body 4 through the inlet pipe 3. Then, the operator can turn on the air pump 91 and the stirring motor 21. The gas will enter the connecting chamber 93 through the air pump 91 and the air inlet pipe 96, and be dispersed into each bubble stone 92 through the connecting pipe 94. The bubble stone 92 disperses the gas into small bubbles, which will automatically rise to the top of the sewage. At this time, the stirring motor 21 will drive multiple sets of stirring blades 22 through the stirring column 23. The stirring blades 22 will stir the sewage. When stirring the sewage, the stirring blades 22 will also interfere with the bubbles, slow down the rising speed of the bubbles, and increase the combination time of the sewage and oxygen. The check valve 95 can effectively prevent the sewage from flowing back to the outside when the air pump 91 is not in use.

[0031] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
