摘要
The present invention relates to a wastewater treatment apparatus equipped with a high-efficient hybrid floatation process. The waste water treatment apparatus equipped with high-efficient hybrid floatation process comprises: a coagulation reaction tank which forms floccules by supplying a chemical to wastewater and thus causing reaction and coagulation; and a dissolved air flotation tank which is connected to the coagulation reaction tank, and treats coagulated floccules and fine bubbles by bringing them into contact with each other and then floating them; wherein the dissolved air flotation tank comprises a high-concentration treatment tank configured to act as a pre-treatment region where the coagulated floccules and sediments are treated by floating them by means of the fine bubbles; a low-concentration treatment tank configured to act as a post-treatment region where small floccules not treated in the high-concentration treatment tank are treated by floating them by means of a relatively long residence time; and a separation plate disposed between the high-concentration treatment tank and the low-concentration treatment tank to separate the high-concentration treatment tank and the low-concentration treatment tank.;COPYRIGHT KIPO 2016
