<p>A waste treatment apparatus is provided, which is capable of performing volume reduction-annihilation treatment by decomposing wastes by microorganisms while the wastes are agitated efficiently. A waste treatment apparatus 10 decomposes the wastes by the microorganisms to perform annihilation treatment. The waste treatment apparatus 10 includes a treatment tank 14 which accommodates the microorganisms together with the waste, and an agitation means 18 for agitating the microorganisms together with the waste. The agitation means 18 includes a plurality of agitating tools 66a and 66b arranged at predetermined intervals in the axial direction of a rotation shaft 54. The agitating tools 66a and 66b have paddle arms 70a and 70b, respectively, which are disposed so as to be opposed to each other in a diameter direction of the rotation shaft 54, and blades 72a and 72b, respectively, which are disposed at predetermined distances apart from an inner wall of the treatment tank 14 and are inclined with respect to the axis of the paddle arms 70a and 70b. The blade 72a 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 70a approaches the rotation shaft 54. The blade 72b 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 arm 70b approaches the rotation shaft 54.</p> |
