Disclosed is a multi-shaft cohesion apparatus that is capable of stirring raw water in a cohesion area by using only one driving unit and of removing scum floating on a water surface of the raw water. Also, the apparatus may uniformly remove the scum over the cohesion area without a dead space and sharply improve scum remove and discharge efficiency. The apparatus includes a driving unit disposed outside the cohesion area; two-shaft output deceleration unit receiving the rotation force of the driving unit to divide the rotation force of the driving unit into at least two rotation forces, thereby outputting by decelerating the rotation forces at ratios different from each other; a scum removing unit receiving one of the at least two rotation forces decelerated at predetermined ratios after separated from the two-shaft output deceleration unit to rotate, thereby removing the scum floating on the water surface of the raw water in the cohesion area; and at least one impeller receiving the other of the at least two rotation forces decelerated at predetermined ratios after separated from the two-shaft output deceleration unit to rotate, thereby stirring the raw water in the cohesion area. |
