[0025] Specifically, when sewage is treated, the sewage is first discharged into the inside of the funnel 7, and then the sewage flows into the inside of the treatment box 1 through the water inlet pipe 9. As the water level rises, the floating plate 10 is driven to move upwards. The movement of the floating plate 10 drives the movement of the piston plate 16. In the initial state, the inside of the medicine cylinder 3 is full of medicine. When the piston plate 16 moves upwards, the piston plate 16 pushes the medicine in the inside of the medicine cylinder 3 to the inside of the treatment box 1 through the first connecting pipe 171 and mixes with the wastewater. The first one-way valve 181 is arranged to allow the medicine to flow out from the inside of the medicine cylinder 3 in one direction only. After the wastewater is discharged, the medicine adding work is automatically stopped, and the wastewater treatment is completed. At this time, the floating plate 10 moves downwards, and the movement of the piston plate 16 is accelerated under the action of gravity. During the downward movement of the piston plate 16, the medicine stored in the inside of the medicine tank 2 is pumped into the inside of the medicine cylinder 3, so that the medicine in the inside of the medicine cylinder 3 is quickly replenished. The second one-way valve 182 is arranged to allow the medicine to flow from the inside of the medicine tank 2 to the inside of the medicine cylinder 3 only.

[0026] It should be noted that the automatic medicine supply device can be arranged in one or more groups, and the inside of the medicine tank 2 can be provided with a plurality of medicine cavities corresponding to the automatic addition of a plurality of medicines.
