PROBLEM TO BE SOLVED: To provide a slurry treatment apparatus capable of uniformly concentrating slurry into high concentration.SOLUTION: The slurry treatment apparatus 1 includes: a concentration tank 2 for separating the slurry A into concentrated slurry B obtained by concentrating the slurry A and a supernatant C by settling solid particles in slurry A; a nearly funnel-like concentration tank body 21 having a discharge port 24 for discharging the concentrated slurry B on an inner bottom part 23, a cylindrical drum 22 for storing the supernatant C in the upper part, and an over flow part 25 for discharging the supernatant C in the upper par; a slurry supply path 4 for supplying the slurry A to the inside of the concentration tank body 21; and a stirring device 6 arranged freely rotatably inside the concentration tank body 21. The stirring device 6 has a stirring blade 61 for allowing to flow upward the concentrated slurry B sinking from the upper side of the concentration tank body 21, a rotary shaft 63 on which the stirring blade 61 is provided and a stirring drive motor 62 for rotating the rotary shaft 63. |
