Abstract

PURPOSE: To easily regenerate intermediate water of which quality is in the middle between that of drinking water and sewage, from waste water, by adding coagulant, when removing the suspended substance in waste water with air bubbles by floatation method, to coagulate the suspended substance and organic matter at high efficiency, and floating with air bubbles at high speed, in a floatation system waste water treatment equipment.
CONSTITUTION: Waste water 14 is supplied into the upper part of a coagulant mixture band 2, together with a coagulant 15 injected into the tube duct, and falls down while causing whirl, so that the coagulant and suspended substance are mixed well. The suspended substance produces aggregate, which flows into an air bubble dispersion band 3. On the other hand, pressurized water 16 containing fine air bubbles is injected into the air bubble dispersion band 3 from a supply pipe 8, and is made to contact and deposit on the aggregate to flow into an aggregation floating band 4, so that the aggregate floats up with air bubbles. The aggregate 19 floating up is discharged from a drain port 11 together with overflow liquid. The treated water 17 removed aggregate 19 by separation is taken out from a discharge port 12, so that intermediate-quality water used in toilet flushing, air conditioning and car wash may be easily obtained.
