摘要

The invention relates to a round settling tank (1) for separating sludge from waste water. This type of tank comprises an inlet (2) to allow the waste water to flow into the settling tank (1), a clearing device for the settled sludge which scrapes along the base (7) of the settling tank (1), as well as a withdrawing device (8) for the sludge and an outlet (10) for the clear water. According to the invention these settling tanks operate with turbulence in the separating area and a stilled water flow in other areas. The waste-water inlet (2) discharges at the height of the thickening and evacuating layer (11) such that the settling capacity is raised considerably.
