[0024] It should be noted that when sewage needs to be disinfected, the sewage is pumped into the disinfection tank 1 by a pump, and the powder medicine is mixed with water or other solutions and agents and pumped into the dosing mechanism 4 by a pump. Through the first stirring mechanism 7 provided, the agents stored in the dosing mechanism 4 can be mixed to prevent solidification. When the stored material is powder medicine mixed with water or other solutions, through the first stirring mechanism 7, they can be fully mixed, which is beneficial to subsequent spraying operations. Through the dosing mechanism 4 provided, the agents can be sprayed onto various parts of the disinfection tank 1, which is beneficial to expanding the spraying range of the agents, so that the agents can quickly contact the sewage in different parts, thereby improving the disinfection rate of the sewage. Through the second stirring mechanism 11 and the mixing mechanism 8 provided, the sewage and the agents in the disinfection tank 1 can be fully stirred and mixed, further improving the disinfection rate of the sewage. At the same time, the first stirring mechanism 7, the mixing mechanism 8 and the second stirring mechanism 11 all operate based on the movement of the dosing mechanism 4, which is beneficial to reducing energy consumption and the cost of sewage treatment.

[0025] As Figure 2 shown, the dosing mechanism 4 includes a screw slide table assembly 401 driven by a driving motor embedded in the outer wall of the top of the disinfection tank 1.
