Summary:PURPOSE: A stacked filtering device with excellent filtering and washing efficiencies can prevent the degradation of filtering efficiency attributable to blockage during filtering, the wall effect, disturbance between filtering mediums, etc. by laminating diverse filtering mediums with different specific gravities and particle diameters to form a filtering medium layer. CONSTITUTION: A stacked filtering device with excellent filtering and washing efficiencies has a filter tub (110) in which an inflow line is on the upper part and an effluent line and backwashing line are wound together and are on the lower part, a lower part medium layer (120) on the lower part of the filter tub, a upper part medium layer (130) on the upper part of the lower part medium layer consisting of filter mediums with lower specific gravities and greater particle diameters than the filtering medium of the lower part medium layer and a blade (140) of multiple agitating blades parallel to the border between the lower part medium layer and the upper part medium layer.
