ABSTRACT:
A waste treatment apparatus decomposes waste by the microorganisms to perform annihilation treatment. The waste treatment apparatus includes a treatment tank which accommodates the microorganisms together with the waste, and an agitation device arranged to agitate the microorganisms together with the waste. The agitation device includes a plurality of agitating tools arranged at predetermined intervals in the axial direction of a rotation shaft. The agitating tools have paddle arms, respectively, which are disposed so as to be opposed to each other in a diameter direction of the rotation shaft, and blades, respectively, which are disposed at predetermined distances apart from an inner wall of the treatment tank and are inclined with respect to the axis of the paddle arms. The blade on one side is inclined forward in a direction in which the front side thereof with respect to the rotation direction of the paddle arm approaches the rotation shaft. The blade on the other side is inclined backward in a direction in which the rear side thereof with respect to the rotation direction of the paddle arm70bapproaches the rotation shaft.
