<p>PURPOSE: An oxygen supplying apparatus for a circulating type pond is provided to increase the efficiency of water treatment by increasing the contact area of water with respect to oxygen and increasing the dissolved oxygen of the water. CONSTITUTION: An oxygen supplying apparatus for a circulating type pond includes a pump(20), a transferring pipe(30), a dissolution guiding pipe(40), an external air suction pipe(50), and a plurality of collision wings(53). An inlet is formed at the outer circumference of the dissolution guiding pipe and is extended to the vertically direction of the pipe. One end part of the suction pipe is exposed to introduce external air into the dissolution guiding pipe. Another end part of the suction pipe is connected to the inlet. The collision wings are separately arranged along the vertical direction and are extended to the center of the dissolution guiding pipe.</p> |
