PURPOSE: An ultramicro-bubble generating bio-reactor is provided to facilitate a high concentrate organic wastewater treating process by inducing the movement of ultramicro-bubbles and increasing the retention time of oxygen in wastewater. CONSTITUTION: A first circulating part(91) circulates wastewater collected from a wastewater treating apparatus. A heat exchanging part(40) cools the circulating wastewater. A second circulating part(92) is in connection with one end part of the heat exchanging part. A first pump(21) and a second pump(22) provide power to circulate the wastewater. A first nozzle(81) and a second nozzle(82) generate ultramicro-bubbles. A first bubble moving part(51) and a second bubble moving part(52) respectively surround the nozzles to form a closed space. A first bubble guiding part(61) and a second bubble guiding part(62) guide the ultramicro-bubbles to the bottom part of a bio-reactor. |
