[0002] With the acceleration of urbanization and the development of industrialization, the amount of sewage is increasing rapidly. If the sewage is discharged directly without effective treatment, it will seriously pollute the water body and affect the ecological environment and human health. Therefore, building a sewage treatment plant to treat sewage centrally is an important measure to protect the water environment and promote sustainable development. As an important part of the sewage treatment process, the aeration grit chamber in the sewage treatment plant has the functions of oxidizing organic matter, removing sludge particles and precipitating sludge. Therefore, the operation efficiency and stability of the aeration grit chamber directly affect the treatment effect of the entire sewage treatment plant. In the sewage treatment process, if the floating residue on the surface of the sewage is not removed in time and effectively, these residues will accumulate over time, not only significantly increasing the difficulty of subsequent cleaning operations, but also posing an additional burden on the subsequent treatment in the sewage treatment process, affecting the normal operation efficiency and treatment efficiency, and thus shortening the service life of key equipment in the entire sewage treatment system and increasing maintenance costs.

[0003] Currently, the mainstream method for treating the floating residue of the aeration grit chamber relies on manual operation, which usually requires cleaning operation 1 to 2 times a day. This highly dependent on manual method not only consumes a lot of labor resources and increases labor costs, but also in actual operation, the area around the aeration grit chamber often produces hydrogen sulfide and other harmful gases due to biochemical reactions of sewage, which pose a serious threat to human health and bring great risks to the safety of on-site operators, reducing the safety of the working environment.
