[0031] Specifically, in use, the medicament to be fed is first put into the medicament box 5, and then the medicament is fed into the stirring tank 13 through the discharge pipe 3. The medicament in the stirring tank 13 is fully stirred by the stirring mechanism. After the stirring is completed, the driving motor 21 is turned on, the driving motor 21 drives the worm 16 to rotate, the worm 16 drives the worm wheel 10 to rotate, the worm wheel 10 drives the rotating main shaft 9 to rotate, the direction of rotation is controlled, the rotating main shaft 9 drives the stirring tank 13 to tilt forward, and the medicament in the stirring tank 13 is poured out from the top of the stirring tank 13. The inclination angle of the stirring tank 13 is controlled, so that the inclination angle of the stirring tank 13 can be greater than 90 degrees, so that the medicament in the stirring tank 13 can be completely poured out. This medicament feeding method can quickly feed the stirred medicament into the wastewater, which is conducive to the full mixing of the medicament and the wastewater, can fully play the role of the medicament, and can improve the sedimentation effect of the wastewater. Moreover, this medicament feeding method can also ensure that the medicament in the stirring tank 13 can fully enter the wastewater, effectively preventing the solid particle medicament from settling at the bottom of the stirring tank 13, and also preventing the solid particle medicament from blocking the pipeline.
