[0034] The above solution provides sufficient aeration inside the system through the combination of the air pump 41, the main pipe 42 and the branch pipe 43, which promotes the transfer and dissolution of oxygen in the water body and is beneficial to the improvement of water quality.

[0035] The working principle of the utility model is as follows: when in use, sewage is first added into the sedimentation tank 11, and the sewage in the sedimentation tank 11 is preliminarily filtered through the oblique tube filter 111. As the amount of water in the sedimentation tank 11 increases, the water filtered by the oblique tube filter 111 enters the hydrolysis tank 12. At this time, bacteria are added to the sewage in the hydrolysis tank 12 through the bacteria adding box 5, and the oxygen transfer and dissolution in the water body are promoted through the aeration device 4 to improve the water quality. After that, the water in the hydrolysis tank 12 is pumped into the oxidation tank 13 through the water pump 6, and the water is promoted through the bacteria adding box 5 and the aeration device 4 in the oxidation tank 13. The oxygen in the body is transferred and dissolved to improve the water quality again. Then, the water in the oxidation pool 13 is pumped into the oxidation pool 2 14 through the water pump 6. At the same time, the water in the second sedimentation tank 15 is pumped into the mixing tank 21 through the water inlet device 22 until the water in the mixing tank 21 overflows from the drain pipe 25. Then, the medicine is pumped into the mixing tank 21 through the dosing pump 27, and the medicine and water are fully mixed through the stirring piece 24. Then, it is added to the oxidation pool 2 14 through the water outlet device 23, and the water quality is improved again through the bacteria addition box 5 and the aeration device 4 in the oxidation pool 2 14. Then, the oxidation pool is pumped into the oxidation pool 14 through the water pump 6. The water in the second settling tank 14 is pumped into the secondary settling tank 15 for re-precipitation, and finally the water in the secondary settling tank 15 is pumped into the filter 32 for filtration through the pump 34, and discharged into the clean water tank 17 through the water pipe 36. When the filter 32 is blocked, the water will enter the anti-blocking pipe 37 connected to the input end of the filter 32, and flow into the recoil tank 16 through the reflux pipe 38. When a certain amount of water accumulates in the recoil tank 16, the water will rush out of the water pipe 7 and flow to the water inlet pipe 9 due to the height difference. When passing through the dyeing box 8, the water flowing through will be dyed, and finally flow into the hydrolysis tank 12 for water treatment again; The anti-blocking pipe 37 located at the side of the water inlet end of the filter 32 can prevent solid particles or impurities from clogging the filter 32, ensuring the normal operation and long-term stability of the filter 32. When the filter 32 is blocked, the blocked water will automatically flow back to the backwash tank 16 through the reflux pipe 38. This process is automated and does not require manual intervention, which is conducive to the simplicity and stability of operation. The dyeing box 8 is located after the outlet pipe 7 and can dye the water flowing out of the backwash tank 16, so that the staff can quickly notice the blockage problem, so as to take cleaning or maintenance measures in time to ensure the continuous and stable operation of the entire water treatment system.

[0036] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
