Solid floating objects and liquid floating objects generally require two sets of structures to be removed. It is impossible to use one set of structures to remove solid floating objects and liquid floating objects at the same time, which increases the occupied space of the floating object removal device; 2. Usually, the staff needs to manually clean up the liquid floating objects after removal, and the liquid floating objects after removal cannot be automatically discharged, which reduces the sewage treatment efficiency; 3. There is usually still a lot of sewage in the liquid floating objects after removal, and the excess sewage in the liquid floating objects cannot be cleaned, resulting in the liquid floating objects occupying more space and increasing the subsequent cleaning times of the liquid floating objects.
