Provided is a pressurized floating tank that is a water treatment facility. The pressurized floating tank can either comprise a tank body in which raw water mixed with chemicals is fed and which is aerated and floated in order to discharged treatment water, and a jet-nozzle means that is provided to the tank body and is formed in a raw water feeding type so as to aerate the raw water mixed with the chemicals and float contaminants to be removed, or comprise an assembled tank body in which raw water mixed with chemicals is fed and which is aerated and floated in order to discharged treatment water, and a jet-nozzle means that is provided to the tank body (10) so as to aerate the raw water mixed with the chemicals and float contaminants to be removed. By means of the present invention, a new floating process is formed in order to replace existing pressurized floating tanks and decrease the total amount of phosphorous that is discharged from middle- and small-sized waste water treatment facilities disposed in a river system region (drinking water source). Through optimal management for phosphorous that is fed in a river system, the production of algae is controlled and eutrophication is prevented. Existing agitation facilities, compressed tanks, and compressors are not needed so that the pressurized floating tank can be easily maintained and the used amount of energy can be minimized. Also, the pressurized floating tank is entirely compact. |
