BACKGROUND With the acceleration of urbanization and the improvement of industrialization, the amount of sewage discharged is constantly increasing, and the types and contents of pollutants are also constantly rising. The demand for sewage treatment is becoming increasingly urgent. As one of the key device in sewage treatment, the aeration system introduces air into the sewage to increase the dissolved oxygen content in the water, promoting the biochemical reactions of microorganisms and achieving the purpose of purifying water quality. Its development is of great significance for improving sewage treatment efficiency, improving water quality, and protecting the environment. The tubular aeration system is low in comprehensive cost and high in oxygen utilization rate, can operate intermittently, is not prone to clogging, and has a constant resistance loss, and thus is widely used.

As a preferred embodiment, the arrangement of the aeration mechanism 1 enables the apparatus to change in size according to actual conditions and processing requirements, so that the size of the entire apparatus is more consistent with that of the sewage treatment tank, thereby improving the treatment efficiency. Meanwhile, the aeration output assembly 2 is driven to rotate circularly, thereby facilitating maintenance and ensuring the treatment efficiency at the same time. A cleaning mechanism is arranged in the aeration pipe cleaner 3, which can clean the aeration output assembly 2 in the aeration pipe cleaner, thereby removing an attachment on a surface of the aeration output assembly, preventing clogging caused by excessive accumulation, and thus ensuring the efficiency of sewage treatment. The aeration pipe detector 4 performs a comprehensive and detailed inspection on the aeration output assembly 2 and records one with a defect. The aeration pipe replacement assembly 5 replaces a defective assembly of the aeration output assembly 2, thereby further ensuring the treatment efficiency. When the water treatment effect is poor or the operating cost is high, the aeration output adding assembly 6 adjusts the number of aeration output assemblies 2 participating in the circulation in a targeted manner, thereby reducing costs and improving efficiency. The arrangement of the aeration output assembly disconnector 7 can separate two adjacent aeration output assemblies 2, thereby facilitating the operation of the aeration output adding assembly 6.

The arrangement of the apparatus fixed foot 13 enables the apparatus to be fixed first, facilitating the automatic installation of the apparatus. The fixed guide groove 17 can fix the rotating fixed assemblies 18 to a certain extent, preventing the rotating fixed assemblies from disengaging during movement and thus affecting the working progress. One group of the rotating fixed assemblies 18 is fixed relative to the embedded rotating belt 16, which can serve as an anchor point to a certain extent, thereby preventing the rotating fixed assemblies from sliding relative to the embedded rotating belt 16 during rotation. Further, the aeration pipe cleaner 3, the aeration pipe detector 4, the aeration output adding assembly 6, the telescopic waterproof plate 11, and the right-angle edges of the right-angle telescopic frame 12 are all telescopic structures. As a preferred embodiment, the aeration pipe cleaner 3, the aeration pipe detector 4, and the aeration output adding assembly 6 are arranged in a telescopic manner, so that the width of the apparatus can be further changed in actual work, thereby enabling the apparatus to be more suitable, and further improving the treatment efficiency.

After the disassembly is completed, the third hydraulic cylinder 54 directly returns to an initial position. The second hydraulic cylinder 53 on the side of the fully functional aeration pipe replacement pipe 52 extends, pushing the fully functional aeration pipe replacement pipe 52 to a position directly above the first falling opening while pushing the ineffective or low-efficiency aeration pipe replacement pipe 52 to the side of the ineffective or low-efficiency aeration pipe replacement pipe 52. Subsequently, the fully functional aeration pipe replacement pipe 52 completes replacement work under the rotation of the first gripper 55. Further, the aeration output adding assembly 6 includes a second protective shell 61, fixed telescopic blocks 62 are slidably arranged at both ends of the second protective shell 61, the other ends of the two fixed telescopic blocks 62 are respectively fixedly assembled on inner walls of the two aeration mechanisms 1, sliding rails 63 are horizontally fixed on two side walls of the second protective shell 61 parallel to the aeration mechanism 1, a plurality of increasing and decreasing members 64 are slidably arranged on the sliding rail 63, a fourth hydraulic cylinder 65 is arranged on one side of the plurality of increasing and decreasing members 64 and the fourth hydraulic cylinder 65 is fixedly assembled on the second protective shell 61, a second falling opening is arranged on a lower end surface of the second protective shell 61 and located on the other side of the plurality of increasing and decreasing members 64, a fifth hydraulic cylinder 66 is fixedly assembled in the middle of an upper end surface of the second protective shell 61 in a vertical manner, and a second gripper 67 is fixedly assembled at a lower end of the fifth hydraulic cylinder 66.
