[0002] When using a treatment pool to treat sewage, the sewage is first discharged into the treatment pool from the water inlet, and then chemicals are added to the treatment pool, and floating objects in the water are precipitated through physical precipitation, so that the sewage is further purified. The inventors have found in daily use that although most of the floating objects in the treatment pool can be precipitated at the bottom of the treatment pool by adding chemicals and physical precipitation, some lighter floating pollutants still float on the water surface due to their lighter weight and are difficult to precipitate, thereby reducing the use effect of the treatment pool and the sewage treatment effect. In addition, some lighter floating pollutants will flow through the outlet trough to the next discharge port, and after preliminary precipitation, the lighter floating pollutants in the water are salvaged by a manual handheld scoop net, thereby ensuring the sewage treatment effect of the treatment pool.

[0003] However, in actual operation, it was found that manual salvage is time-consuming, labor-intensive and inconvenient, and the area of ​​salvage with a scoop net is limited, which may lead to areas that cannot be salvaged or missed. As a result, some lighter floating pollutants are not salvaged and disposed of, and flow from the outlet trough to the next place, reducing the use effect of the treatment pool and the sewage treatment effect.
