As shown, the sedimentation tank 1 of the circular concrete structure, the bottom portion is formed to be inclined downward to the center of the radial direction, the sludge hopper 1a connected to the sludge outflow pipe 1b is formed around the center of the bottom portion A drainage passage 1c is formed around the upper portion so that the treated water can flow over to the next purification place, and the outer sidewall portion 1d outside the drainage passage 1c is an inner sidewall portion 1e inside the drainage passage. It is a structure formed higher.

Inside the inner side wall portion 1e, scum (various impurities of inorganic matter floating on the surface of the water) is prevented from overflowing into the drainage channel 1c, while the treated water above the constant settling separation flows into the drainage channel 1c. The wear 2 in which the slit groove was formed is provided so that it may be. In the center of the settling tank 1, a hollow center column 3 is vertically installed, and a drain hole 3a is formed near the upper end of the center column 3, and the settling tank 3 is formed in the drain hole 3a. The discharge side of the sewage inflow pipe 3b introduced into the center column 3 from the outside of 1) is connected. In addition, a center cage 4 driven by a driving motor M is rotatably installed at an outer circumference of the center column 3, and a bottom portion of the settling tank 1 is supported by the center cage 4.
