[0033] When it is necessary to treat the sewage, the sewage is poured into the water inlet pipe 6, and the sewage can be filtered under the action of the filter plate 7, that is, the sewage begins to enter the anaerobic tank 2 for anaerobic treatment. At the same time, the motor 10 starts to work, because the output end of the motor 10 is connected to the first stirring shaft 11, and the first stirring plate 12 installed on the first stirring shaft 11 also starts to rotate, so as to achieve the purpose of stirring the sewage, that is, the sewage is fully anaerobically treated, and then the sewage is introduced into the aerobic tank 3 through the first water pipe 9, and the sewage can be fully aerobicly treated by the rotation of the first stirring plate 12. Aerobic and anaerobic microorganisms in the sewage can be treated, and then the sewage can be introduced into the liquid medicine pool 4 through the second water pipe 16. At this time, the treatment liquid can be added into the liquid medicine pool 4. At the same time, as the first stirring shaft 11 rotates, the pulley group 13 starts to drive the second stirring shaft 14 to rotate, and the second stirring plate 15 installed on the upper end of the second stirring shaft 14 also starts to rotate, thereby achieving the purpose of sewage treatment, which can effectively ensure that the sewage and the liquid medicine are fully in contact. Finally, the sewage can be introduced into the sedimentation tank 5 for sedimentation through the second water pipe 16 set on the right side, and the water after the sedimentation is completed is discharged through the outlet pipe 8;

At this time, the pulling plate 18 can be moved upwards, and because a scraper plate 17 is installed at the lower end of the pulling plate 18, the scraper plate 17 begins to move upwards, so that the sludge inside the treatment tank shell 1 can be scraped off, and then discharged through the pulling plate 18. When it is necessary to discharge the liquid medicine, as the second stirring shaft 14 rotates, the driving wheel 23 installed on the second stirring shaft 14 begins to rotate, that is, the driving wheel 23 begins to push the moving plate 24, and at this time the moving plate 24 The installed connecting spring 25 begins to be compressed and deformed, that is, as the moving plate 24 moves, the air storage bag 26 installed on the moving plate 24 begins to be squeezed, that is, the gas in the air storage bag 26 enters the expansion bag 27 through the catheter, and the expansion bag 27 begins to expand. As the expansion bag 27 expands, it begins to block the inner wall of the drug delivery tube 28, thereby stopping the drug delivery. As the pushing wheel 23 continues to rotate, the pushing wheel 23 no longer pushes the moving plate 24, and then under the action of the connecting spring 25 restoring the deformation, the connecting spring 25 begins to pull the moving plate 24 to move to the right, and at this time, the gas in the expansion bag 27 enters the air storage bag 26 again, thereby starting to deliver the drug solution again.
