The treatment agent storage tank 13 is arranged on the top of the sealing cover 5, and the treatment agent storage tank 13 is arranged on the bottom of the sealing cover 5. The treatment agent storage tank 13 and the treatment agent filling tank 14 are connected through a feed pipe 18, and a first check valve 20 is arranged on the feed pipe 18. The treatment agent filling tank 14 is provided with a discharge pipe 19, and a second check valve 21 is arranged on the discharge pipe 19. The piston 15 The sliding part 16 is arranged on the piston 15 and extends to the outside of the treatment agent filling tank 14. The spring 17 is sleeved on the sliding part 16. The two ends of the spring 17 are respectively arranged on the treatment agent filling tank 14 and the sliding part 16. The stirring assembly includes a stirring shaft 10, a stirring blade 11 and a stirring rod 12. The stirring shaft 10 is rotatably arranged on the sealing cover 5 and is located in the stirring mixing tank 1. The stirring blade 11 and the stirring rod 12 are both arranged on the stirring shaft 10. The stirring shaft A cam 22 is sleeved on 10, a contact plate 29 is provided on the sliding rod 16, and the contact plate 29 contacts the cam 22; a slot 30 is provided on the contact plate 29, and the cam 22 is located in the slot 30; a bracket is provided on the sealing cover 5, and a second motor 28 is provided on the bracket, and one end of the stirring shaft 10 is arranged on the output shaft of the second motor 28; a liquid discharge port 31 is provided on the solid-liquid separation box 3, and a second solenoid valve 32 is provided on the liquid discharge port 31; two groups of treatment agent batch filling mechanisms 2 are symmetrically provided.

[0025] The solid-liquid separation mechanism 4 includes a solid-liquid separation cabin 23, a rotating shaft 24, a spiral blade 25 and a filter screen 26. The solid-liquid separation cabin 23 is arranged in the solid-liquid separation box 3, and one end of the solid-liquid separation cabin 23 extends to the outside of the solid-liquid separation box 3. The solid-liquid separation cabin 23 is provided with a solid discharge port 8 at one end outside the solid-liquid separation box 3.

The solid-liquid separation cabin 23 is provided with a first motor 27, and one end of the rotating shaft 24 is arranged on the output shaft of the first motor 27.

[0026] During specific use, the treatment agent is added into the treatment agent storage tank 13, the sewage is added into the stirring and mixing tank 1, and then the second motor 28 is started. The stirring shaft 10 is driven to rotate by the second motor 28. On the one hand, when the stirring shaft 10 rotates, the cam 22 is driven to rotate. The rotation of the cam 22 and the spring 17 will cause the sliding rod 16 to slide back and forth. The sliding rod 16 drives the piston 15 to move back and forth in the treatment agent filling tank 14. In the process of the reciprocating movement of the piston 15, the treatment agent stored in the treatment agent storage tank 13 can be extracted in batches and added to the stirring and mixing tank 1 to mix with the sewage. On the other hand, when the stirring shaft 10 rotates, it will also drive the stirring blade 11 and the stirring rod 12 to rotate to fully mix and stir the sewage and the treatment agent. By adding the treatment agent in batches for multiple times, the mixing effect of the treatment agent and the sewage can be improved.

[0027] After the sewage treatment is completed, the first solenoid valve 9 is opened, so that the solid-liquid mixture in the stirring mixing tank 1 enters the solid-liquid separation cabin 23 through the discharge pipe 7, and the first motor 27 drives the rotating shaft 24 and the spiral blade 25 to rotate to transport the solid-liquid mixture in the solid-liquid separation cabin 23. When the solid-liquid mixture passes through the filter screen 26, the liquid passes through the filter screen 26 and flows into the solid-liquid separation box 3, while the solid continues to be transported by the spiral blade 25. Finally, the solid will be discharged from the solid discharge port 8, thereby achieving the purpose of solid-liquid separation. The operation is simpler. When the liquid in the solid-liquid separation box 3 needs to be discharged, it is only necessary to open the second solenoid valve 32.

[0028] To sum up, when the second motor 28 can drive the stirring shaft 10 to rotate, firstly, the stirring shaft 10 can drive the stirring blades 11 and the stirring rod 12 to rotate to fully mix and stir the sewage and the treatment agent. Secondly, while the stirring shaft 10 rotates, it will also drive the piston 15 to move back and forth. In the process of the reciprocating movement of the piston 15, the treatment agent stored in the treatment agent storage tank 13 can be extracted in batches and added to the stirring and mixing tank 1 to mix with the sewage, which is conducive to more complete mixing of the agent and sewage, so that the sewage treatment effect is higher. The present scheme is provided with a solid-liquid separation mechanism 4, which is convenient for separating solids and liquids after the sewage treatment is completed.
