Separation apparatus

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 outletthrough which the liquid flows out from the outflow region. 一种分离装置包括：分离槽；设在分离槽内的分隔构件，其包含竖立部分及横向部分，竖立部分具有比分离槽的侧壁中的每一个的高度低的高度，横向部分设置于竖立部分与所述侧壁之间，将分离槽的内部分隔成液体的流入区域和流出区域；在流入区域中敞开的入口，其下部水平面设定成低于竖立部分的上端，其上部水平面设定成高于该上端；筛，其在分隔构件中沿着流入
