Abstract
The present inventions relates to an apparatus for purifying wastewater and a method thereof, which comprises: a stirring part to make bubbles impregnated into floc through high speed stirring by adding floc forming materials to influent and stirring them; an air supply part to supply air to the stirring part to make more bubbles impregnated; a pumping part to conduct pressurized conveying of the floc included treatment water; a cyclone part to separate high density floc to downstream and treatment water with low density floc to upstream from the pressurized treatment water; and a flotation part to separate floc from the treatment water with floc supplied from the cyclone part. Therefore, the present invention have an effect that it is possible to improve purification speed of wastewater and obtain good quality of purified water.
