Abstract: A separation apparatus includes: a partitioning member inside a separation tank, includes erect and transverse portions, and partitions the tank into inflow and outflow regions of a liquid; an inlet of which a lower level is set to be lower than an upper end of the erect portion and an upper level is set to be higher; a screen in the erect portion along a flow direction of the liquid; a swirling inducing member in the erect portion intersecting with the flow direction of the liquid; a screen in the transverse portion; a dividing member dividing the liquid flowing in from the inlet into flows along side walls of the separation tank; a retaining member at a downstream side in the flow direction and retains the substance having the specific gravity less than that of the liquid; and an outlet through which the liquid flows out from the outflow region.
