More particularly, the present invention relates to a floating body removing device, which minimizes shaking when lifting and lowering a buoyant body, disperses frictional force and load transmitted to a supporting bracket part as much as possible to improve durability of the product, And more particularly, to a scum removing device capable of finely adjusting the position of the scum discharging part irrespective of the buoyant body and the water level, thereby reducing the amount of the treated water discharged when the scum is removed.

In general, algae, which cause scum, is a group of growing organisms that ingest carbonic acid gas and organic salts in the water and act as a photosynthetic agent. It is widely distributed in cleanup sedimentation sites, for example, water purification plants and sewage treatment plants, .

In order to remove the scum in the ordinary water treatment process or the sewage treatment process, an operation method of suppressing the generation of air bubbles that affect the scum generation is applied, or a method in which chemicals are supplied and processed is used. The treatment efficiency is extremely low, and it is economically disadvantageous because it requires a small amount of expenses such as operation cost and drug use cost.

At present, the removal of scum is a gradual move from the past due to the manual operation, and gradually progressed to the use of mechanical equipment. However, existing facilities for removing scum have a problem of not being able to appropriately cope with a change in the water level of the treatment tank because the scum floated by simple up-and-down movement operation is removed.
