An apparatus for dissolved air floatation of sludge is provided to improve the floating effect of the sludge and prevent the sludge from being deposited on a bottom surface within the tank, by using an air injecting unit and a stirrer installed within the tank so as to prevent the sludge from agglomerating. An input portion(11) is installed at a lower portion of a tank(10) such that the input unit communicates with an inside of the tank. An output portion(12) is installed at an upper portion of the tank. Sludge is inputted into the tank through the input portion, and outputted from the tank through the output portion. A stirrer(20) is composed of a stirring pole(21) inserted in the tank along a length of the tank, and a stirring wing(22) joined to an outer circumferential surface of a lower portion of the stirring pole. A reduction member(30) is installed on the tank. The reduction member has a motor(31) joined to one side of the stirrer to supply a rotation force to the stirrer. An air injecting unit(40) is installed at a lower portion within the tank to inject air into the tank. |
