[0029] The cooperation principle of the pretreatment mechanism 8 and the stirring mechanism 9 is as follows:

[0030] The sewage to be treated is discharged into the tank body 1 through the sewage inlet 2. When the sewage is discharged into the tank body 1, the liquid level of the sewage in the tank body 1 can be detected by the magnetic flap liquid level meter 7. By observing the liquid level of the sewage in the tank body 1, it can be avoided that the liquid level of the sewage is too high to overflow the dispersion disc 17. At the same time, according to the liquid level of the sewage observed by the magnetic flap liquid level meter 7, the appropriate medicine for treating the sewage is put into the dosing hopper 6 to avoid the situation that too much or too little medicine is added due to the unknown amount of sewage, ensuring the accuracy of dosing. When the medicine is put into the dosing hopper 6 and enters the dosing port 5, the driving motor 16 drives the first rotating rod 14 at both ends of the front crushing tooth roller 13 to rotate in the corresponding rotating hole 10 opened on the two side walls of the dosing port 5. At this time, because the circular gear 15 installed on the outer side end of the first rotating rod 14 at the right end of the front and rear symmetrical crushing tooth roller 13 meshes together, the two circular gears 15 will make relative rotation operation, and the first rotating rod 14 will drive the two crushing tooth rollers 13 to realize synchronous relative rotation operation, so as to crush the blocky medicine in the medicine and achieve the purpose of dispersing the blocky medicine. At the same time, under the drive of the front circular gear 15, the first bevel gear 21 will rotate synchronously through the connecting shaft 20, and under the rotating meshing action, it will drive the second bevel gear 24 to rotate, so that the second bevel gear 24 drives the second rotating rod 23 to rotate in the bearing 12 installed in the top hole 11. The second rotating rod 23 will drive the stirring shaft 22 passing through the through hole 18 in the top surface of the dispersion disc 17 installed in the tank body 1 to rotate, so that the push plate 25, the brush plate 26 and the stirring rod 28 installed on the outer wall of the stirring shaft 22 rotate synchronously. The push plate 25 can push the medicine accumulated after the crushing pretreatment from the dosing port 5 to one side direction in the rotating process, so that the medicine can be evenly spread on the top surface of the dispersion disc 17. At the same time, through the dispersion holes 19 opened on the top surface of the dispersion disc 17, the medicine can be evenly scattered downward and fall into the water surface of the sewage in the tank body 1. The brush 27 installed on the bottom surface of the brush plate 26 can clean the upper surface of the dispersion disc 17 when it rotates, which can prevent the dispersion holes 19 from being blocked by the medicine. In combination with the rotation of the stirring rod 28, the sewage in the tank body 1 can be stirred, and at the same time, the medicine scattered on the water surface can be fully and uniformly dissolved and mixed with the sewage, further in combination with the use of the electric heating and heat preservation jacket 29, the sewage in the tank body 1 can be heated by the electric heating and heat preservation jacket 29, so that the medicine can be quickly activated and dissolved with the sewage in the stirring process, which can play a role of heating and stirring the medicine for the sewage, thereby improving the treatment effect and efficiency of the sewage. Finally, after the sewage is dosed and stirred, the sewage treated in the tank body 1 can be discharged through the sewage outlet 3 by opening the sewage valve 4.
