<p><P>PROBLEM TO BE SOLVED: To provide a urine sewage treatment apparatus capable of effectively decomposing urine sewage by circulating the urine sewage containing fine bubbles in an aeration tank provided with carriers carrying microorganisms for decomposing the urine sewage. <P>SOLUTION: Two aeration tanks provided with carriers 3, 10, on the surfaces of which microorganisms are deposited, are prepared. An aeration/discharge water pump device 6 equipped with a submerged pump 5 with an induction pipe 4 attached to the suction side is installed at the bottom of the first aeration tank 2 while installing the second aeration tank 7 at the upper part of the first aeration tank 2. The urine sewage discharged from the submerged pump 5 is discharged in the second aeration tank 7 from a nozzle 9n of the first discharge means 9. At the same time, the sewage in the second aeration tank 7 is discharged to return to the first aeration tank 2 through a nozzle 14n of a fine bubbles injecting means 14 connected to a discharge pipe 12 for return having an air introduction pipe 13 installed therein. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
