<p>An apparatus for treating organic waste water including a treating tank (1) equipped with oscillatable submerged type contactors in which the organic waste water is treated. A top mixer (4) is disposed under water in a top portion of the treating tank for creating a current of water in agitated condition. Pipe mixers (5) are disposed below the top mixer, each pipe mixer including a pipe which is open at both ends and a band-like agitating blade fitted in the pipe and having a baffle plate portion. One end opening of each pipe mixer is positioned below the top mixer and the other end opening thereof is positioned in a lower portion of the treating tank, so that the current of water from the top mixer can pass through the pipe mixer from the one end opening toward the other end opening and can be discharged from the other end opening. An air feeder pipe (7) extends from an external source (6) to a position intermediate between the water-current generating top mixer (4) and the pipe mixers, the tip of the feeder pipe being open at the intermediate position. <IMAGE></p> |
