<p>PROBLEM TO BE SOLVED: To provide waste treatment equipment having a high stirring performance, unlikely to cause poor fermentation, capable of shortening a processing time for drying/composting organic waste, and capable of reducing a generation amount of malodorous substances; and to provide a waste treatment method.SOLUTION: Waste treatment equipment 1 comprises a vertical container 2, a rotation shaft 3, stirring blades 4, air supply means 6, and exhaust means 9. The stirring blades 4 are arranged in three or more stages apart from one another from the bottom of the rotation shaft 3 to the top thereof, and are linearly extended toward the inner wall side of the container 2 from the rotation shaft 3. Air holes 4d communicating with the air supply means 6 are provided on the stirring blade in the bottom stage, and each stirring blade has an inclined surface with a prescribed inclination angle on a front side in the rotation direction thereof. The inclination angle of the inclined surface of the blade in the top stage is 60 to 85 degrees, the inclination angle of the inclined surface of the blade in the bottom stage is 15 to 25 degrees, and the inclination angle of the inclined surface of a blade in any stage other than the top and bottom stages is 35 to 45 degrees. The content volume of the container is 15 mor more, and the blowing amount (m) per minute by the air supply means is 1/4 or more of the content volume (m) of the container.</p> |
