That is, due to the circular hopper shape of the main housing 11, the wastewater flowing into the main housing 11 through the wastewater inflow passage 12 at a constant pressure is swirled along the inner wall of the main housing 11 At this time, the sludge contained in the wastewater is moved toward the inner wall of the main housing 11 by the centrifugal force, so that the density of the sludge increases toward the lower end of the main housing 11, The water and the sludge are separated from each other and a rising vortex is formed at the center of the main housing 11. [

The wastewater inflow path 12 is connected to the upper end side of the main housing 11. Wastewater flowing at a predetermined pressure through the wastewater inflow path 12 flows into the main housing 11, It is preferable that the waste water inflow path 12 is connected to the upper end side surface of the main housing 11 in a tangential direction so as to effectively induce the turning.

The wastewater pump 13 is configured to pump wastewater into the wastewater inflow path 12. The wastewater is supplied to the inside of the main housing 11 through the wastewater inflow path 12 by the pumping force of the wastewater pump 13. [ So that the wastewater flowing into the main housing 11 can be pivoted along the inner wall of the main housing 11, and the wastewater from which the sludge has been removed from the wastewater can flow into the main housing 11, So that it can rise to the central portion of the body 11.

The treatment water flowing into the lower portion of the auxiliary housing 21 and rising is guided by the inclined lower surface of the treatment feeding guide plate 23 so that the treatment water flows in the treatment water passage gap (231), the space is suddenly enlarged, and the pressure drop of the treated water and the flow velocity decrease.

At this time, the residual sludge remaining in the treated water is separated from the treated water due to the pressure drop and the flow velocity lowered, and settles to the lower end of the upper surface of the treated feeding plate 23.

Meanwhile, in one embodiment of the present invention, the plurality of the treatment feeding-and-collecting plates 23 are arranged in a stacked manner in the vertical direction inside the auxiliary housing 21, So that the residual sludge can be more reliably removed.
