[0023] Furthermore, an annular spray block 5 is provided between the top and bottom of the inner sidewall of the mixing tank 1. A liquid delivery pipe is provided on one side of the top of the annular spray block 5, which is connected to the external liquid storage tank. The annular spray block 5 is uniformly provided with nozzles on its inner side and bottom. An annular toothed block 17 is provided in the sidewall of the mixing tank 1 at the bottom of the annular spray block 5. An L-shaped brush 15 facing the annular spray block 5 is provided on one side of the top of the annular toothed block 17. An annular groove is provided in the sidewall of the mixing tank 1 corresponding to the annular toothed block 17. An annular limiting frame 18 is provided on the inner wall of the mixing tank 1 at the bottom of the annular toothed block 17. A support cover 9 is provided on both sides of the mixing tank 1 at the middle position corresponding to the annular toothed block 17. A motor 14 is provided at the middle position of the top of the support cover 9 near the side of the mixing tank 1. The output end of the motor 14 extends through the bearing to the support cover 9 and is provided with a gear 16.

[0024] In use, the motor 14 can be started to drive the gear 16 on its shaft to rotate, which in turn drives the annular toothed block 17 that meshes with it to rotate. When the annular toothed block 17 rotates, it is limited by the annular limit frame 18. Then, the annular toothed block 17 drives the L-shaped brush 15 to rotate and clean the nozzle of the annular spray block 5. This can prevent impurities from adhering to the nozzle and affecting its spraying effect. When spray cleaning is required, the cleaning liquid in the storage tank can be sent into the annular spray block 5 through the liquid delivery pipe so that the cleaning liquid can be sprayed out to clean its interior.
[0025] An annular frame 8 is provided in the middle of the inner wall of the feed box 2, and a slot 23 is provided in the middle of the top two sides of the annular frame 8. A filter plate 3 is provided inside the annular frame 8, and a block 25 is provided in the position of the filter plate 3 corresponding to the slot 23.

[0026] When in use, the clip 25 of the filter plate 3 can be aligned with the slot 23 and then rotated into the annular frame 8. When rotating, it can be rotated to the stop block 24 to stop rotating. The filter plate 3 can be easily assembled and disassembled and cleaned.
[0027] A connecting plate 12 is provided at the bottom of one side of the mixing box 1, and a detection frame 13 is provided inside the connecting plate 12. An electrochemical sensor 20, an optical sensor 21 and an infrared sensor 22 are respectively provided at the bottom of the detection frame 13. An annular spray block 2 19 is provided at the top of the detection frame 13, and an inlet pipe is provided on one side of the top of the annular spray block 2 19 to connect with an external storage tank. A connecting pipe is provided in the middle of the top of the detection frame 13 to connect with the bottom of one side of the mixing box 1, and a discharge pipe is provided in the middle of the bottom of the detection frame 13.
[0028] In use, the solenoid valve in the connecting pipe can be opened, allowing the mixed liquid inside the mixing tank 1 to enter the detection frame 13. The electrochemical sensor 20 in the detection frame 13 can detect pH value, dissolved oxygen (DO), and heavy metal ions such as mercury and chromium. The optical sensor 21 can detect turbidity, color, and organic matter concentration. The infrared sensor 22 can detect organic matter components, making the detection data more comprehensive. When the detection data meets the standards, it can be discharged for disinfection. When the detection does not meet the standards, the waste liquid can be discharged and sent back to the mixing tank 1. The external cleaning liquid can be sent into the annular spray block 19 through the liquid inlet pipe to clean the interior and prevent abnormalities in subsequent detection data.
[0029] A motor 4 is located at the middle of the top of the mixing box 1. The output end of the motor 4 extends into the mixing box 1 through a bearing and a coupling to a stirring shaft 6. A stirring plate 11 is located at the bottom of the stirring shaft 6. Stirring rods are evenly distributed at the bottom of the stirring plate 11. Stirring rods 7 are evenly distributed on the stirring shaft 6. Vertical scrapers 10 are provided between the other ends of the stirring rods 7. The scrapers 10 are all in contact with the inner wall of the mixing box 1.
[0030] In use, the motor 4 can drive the stirring rod 7 on the stirring shaft 6 and the stirring plate 11 to rotate together, so that the stirring rod 7 can stir and mix the liquid inside, and drive the scraper 10 to rotate, which can prevent the liquid from adhering to the inside for a long time. At the same time, the stirring support rod at the bottom of the stirring plate 11 can rotate to stir the liquid at the bottom, which can make its mixing effect with the chemical agent better.
[0031] In this embodiment, the filter plate 3 is engaged by aligning the locking block 25 with the locking slot 23, and then rotated into the annular frame 8. During rotation, it stops at the stop block 24, allowing for easy assembly and disassembly of the filter plate 3 for cleaning. When waste liquid needs treatment, it can be fed into the feed tank 2, filtered through the filter plate 3, and then piped into the mixing tank 1 to filter out residues. Depending on the waste liquid's characteristics, coagulants, pH adjusters, or oxidizing / reducing agents can then be added. When the chemical agent is mixed and fed into the mixing tank 1, the motor 4 drives the stirring rod 7 on the stirring shaft 6 and the stirring plate 11 to rotate together. The stirring rod 7 stirs and mixes the liquid inside, and also drives the scraper 10 to rotate, preventing the liquid from adhering to the inside for a long time. Simultaneously, the stirring support rod at the bottom of the stirring plate 11 rotates to stir the liquid at the bottom, improving the mixing effect with the chemical agent. During mixing, the solenoid valve in the connecting pipe can be opened, allowing the mixed liquid inside the mixing tank 1 to enter the detection frame 13, thus enabling the detection frame 13 to... The internal electrochemical sensor 20 detects pH value, dissolved oxygen (DO), and heavy metal ions such as mercury and chromium; the optical sensor 21 detects turbidity, color, and organic matter concentration; and the infrared sensor 22 detects organic matter components, making the detection data more comprehensive. When the detection data meets the standards, the liquid can be discharged for disinfection. When the detection data does not meet the standards, the waste liquid can be discharged and returned to the mixing tank 1. External cleaning solution is then introduced into the annular spray block 2 19 through the inlet pipe to clean the interior and prevent abnormalities in subsequent detection data. Normally, after the waste liquid is treated, the motor 14 can be started to drive the gear 16 on its shaft to rotate, so that the gear 16 drives the annular toothed block 17 that meshes with it to rotate. When the annular toothed block 17 rotates, the annular limit frame 18 limits it. Then, the annular toothed block 17 drives the L-shaped brush 15 to rotate and clean the nozzle of the annular spray block 5. This can prevent impurities from adhering to the nozzle and affecting its spraying effect. When spray cleaning is required, the cleaning liquid in the storage tank can be sent into the annular spray block 5 through the liquid delivery pipe, so that the cleaning liquid is sprayed out to clean its interior.
