Abstract
PURPOSE: To purify waste water simply in a short time by the procedure in which a coagulant with air is added to waste water containing oils and solids to form coagulated flocs containing air bubbles and then the flocs are made to buoy up for themselves for separation.
CONSTITUTION: A coagulant is added, with air, to waste water containing oils and solids to form coagulated flocs containing air bubbles with stirring, and then the flocs are buoyed up for themselves for separation. For example, the flocs are buoyed up through a metal tube and then separated. The metal tube 1 is tipped with the porous ceramic or sintered metal tube 2, and air supplied through the pressure air pipe 3 is supplied through the pressure air chamber 4 outside the porous tube 2 to waste water containing oils and foreign matters in the tube. To the aerated waste water, an alkali liquid from the pipe 5, an inorganic coagulant from the pipe 6, and a high polymer coagulant from the pipe 7 are added to form flocs containing air bubbles with stirring. And, the floated flocs are overflowed from the overflow groove 15.
