摘要 <p>An object of the present invention is to provide a compact solid-liquid separator having a high water surface loading which can limit pollutant's outflow even when flocs are insufficiently pelletized. The present invention provides a solid-liquid separator comprising a separation tank, a treated water outlet (16) at the top of the tank, a sludge outlet (17) at the bottom of the tank, a draft tube (3) near the center in an upper inner zone of the tank and connected to a raw water inlet pipe (2), horizontally rotatable multistage stirring blades A (5) in said draft tube, horizontally rotatable multistage stirring blades B (6) immediately below said draft tube, a horizontal baffle (8) below said stirring blades B, a filter medium layer (10) consisting of a floating filter medium around the outside of said draft tube above said stirring blades B, and a screen (12) fixed below the water level above said filter medium layer, and optionally a filter medium-receiving screen (13) around the lower outside of said tube in combination with stirring rods (14) above said screen or aeration nozzles.</p>
