The process of purifying sewage to make it meet the water quality requirements for discharge into a certain water body or reuse is called sewage treatment. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily life of ordinary people. The sewage treatment system is composed of primary sedimentation tanks, filtration devices, oxidation tanks, anaerobic tanks, secondary sedimentation tanks, aeration devices, etc. and is used to purify sewage. In order to reduce the floor space, people usually make a reasonable layout of the above-mentioned facilities to form an intensive sewage treatment facility that is easy to replace the disc aerator.

[0003] The disc aerator is an aeration device used in intensive sewage treatment devices that is easy to replace. It is mainly composed of a drive motor, a reducer, a coupling, a main shaft, a bearing seat, an aeration disc, etc. When in use, the drive motor drives the aeration disc to rotate, and the aeration disc lifts the sewage to achieve the aeration effect. The aeration disc is usually made of two semicircular discs that are connected together. The two semicircular discs are buckled on the outside of the main shaft and connected together with bolts. However, the aeration disc will become loose, displaced, or damaged after working for a period of time. Looseness will cause the aeration disc to The main shaft slides and the transmission capacity decreases, which reduces the aeration effect. The displacement will change the distance between adjacent aeration discs, which will reduce the aeration effect. Workers are required to conduct regular inspections and calibrate and tighten the loose and displaced aeration discs. The maintenance frequency is high, and the process is extremely time-consuming and labor-intensive, which will reduce the sewage treatment efficiency. In addition, the installation and removal of the aeration discs are inconvenient. When the aeration disc is damaged, the replacement process is extremely time-consuming and labor-intensive, which further reduces the sewage treatment efficiency. Therefore, there is an urgent need to design an intensive sewage treatment device that is easy to replace the rotary disc aerator. Summary of the invention
