[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it. Sewage treatment is widely applied in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering, and is also increasingly entering the daily lives of ordinary people.

On the top of the first valve 111, a second conduit 12 is penetrated and hermetically connected. Multiple first conduits 11 can be respectively connected to multiple tank bodies 1. When in use, sewage from the outside is directly introduced from the second conduit 12. A second valve 121 is arranged on the outer wall of the second conduit 12. When all water injection stops, the second valve 121 is used to close the second conduit 12. When it is necessary to close an individual tank body 1, the first valve 111 on the top of the corresponding first conduit 11 is closed. A cover plate 5 is fixed on the top of the first convex block 4. A servo motor 6 is fixed in the middle of the top of the cover plate 5. A rotating shaft 7 is fixed at the power output end of the servo motor 6. Stirring rods 71 are fixed on the outer wall of the rotating shaft 7. A chemical dosing pump 8 is fixed on one side of the middle of the top of the cover plate 5. A nozzle 9 is fixed at the bottom of the chemical dosing pump 8. One end of the chemical dosing pump 8 is fixed with a medicine guiding pipe 10. The other end of the medicine guiding pipe 10 is connected to an external liquid medicine tank. The external liquid medicine is introduced into the chemical dosing pump 8 through the medicine guiding pipe 10. The external liquid medicine is pumped into the nozzle 9 by the chemical dosing pump 8 and sprayed out around through a plurality of spray holes 91 in a circular pattern. The sprayed liquid medicine can directly fall into the water inside the tank body 1.

[0030] Refer to Figure 3 , multiple groups of stirring rods 71 are provided. The multiple groups of stirring rods 71 are arranged vertically and equidistantly. Each group of stirring rods 71 has a plurality of them. The multiple stirring rods 71 are arranged circularly and equidistantly. The servo motor 6 drives the rotating shaft 7 to rotate, driving the multiple groups of stirring rods 71 to rotate simultaneously to stir the water inside the tank body 1. The length of the stirring rods 71 is adapted to the inner wall radius value of the tank body 1.

[0031] Refer to Figure 2 and Figure 3 , the horizontal height value of the top of the top group of stirring rods 71 is less than the horizontal height value of the top of the inner wall of the tank body 1, so that when the stirring rods 71 rotate, the top is located inside the tank body 1 and will not touch the first convex block 4, improving the overall practicality.

[0032] Refer to Figure 4 , spray holes 91 are formed on the outer wall of the nozzle 9. A plurality of spray holes 91 are provided. The multiple spray holes 91 are arranged circularly and equidistantly. The external liquid medicine is pumped into the nozzle 9 by the chemical dosing pump 8 and sprayed out around through the multiple spray holes 91 in a circular pattern.

[0033] Refer to Figure 3 and 4, the spray head 9 penetrates through the middle of the cover plate 5, and the spray holes 91 are located below the cover plate 5, so that the sprayed liquid medicine can directly fall into the water inside the tank body 1. One end of the second conduit 12 is sealed, and the other end of the second conduit 12 is connected to the sewage drain pipe. There are multiple first conduits 11, and the multiple first conduits 11 are connected to the bottom of the second conduit 12 at intervals and sealed. During use, sewage from the outside is directly introduced through the second conduit 12. When all water injection stops, the second conduit 12 is closed by using the second valve 121. When it is necessary to close an individual tank body 1, the first valve 111 at the top of the corresponding first conduit 11 can be closed. The other end of the medicine guide pipe 10 is connected to an external liquid medicine tank, and the external liquid medicine is introduced into the medicine adding pump 8 through the medicine guide pipe 10.

[0034] The implementation principle of a medicine adding device for water treatment in an embodiment of this application is as follows: First, connect multiple first conduits 11 to multiple tank bodies 1 respectively. During use, sewage from the outside is directly introduced through the second conduit 12. When all water injection stops, the second conduit 12 is closed by using the second valve 121. When it is necessary to close an individual tank body 1, the first valve 111 at the top of the corresponding first conduit 11 can be closed. While the sewage is being injected, the medicine adding pump 8 at the top of the corresponding tank body 1 is started. The other end of the medicine guide pipe 10 is connected to an external liquid medicine tank, and the external liquid medicine is introduced into the medicine adding pump 8 through the medicine guide pipe 10. The external liquid medicine is pumped into the spray head 9 through the medicine adding pump 8 and is sprayed out circumferentially through multiple spray holes 91. The sprayed liquid medicine can directly fall into the water inside the tank body 1. At the same time, when the servo motor 6 is started, the rotating shaft 7 is driven to rotate, driving multiple groups of stirring rods 71 to rotate simultaneously to stir the water inside the tank body 1, so that the sewage and the liquid medicine inside the tank body 1 can be fully mixed. Finally, when the reaction is completed, the third valve 31 at the bottom of the corresponding tank body 1 is opened, and the water is discharged from the drain pipe 3.
