Abstract:
PROBLEM TO BE SOLVED: To surely carry out solid-liquid separation by using a dehydration device in which the treatment of a spend neutralization liquid is conducted. SOLUTION: An agitation section 64 is provided on the inside of a sedimentation tank 63, and the agitation section 64 is constituted of a rotary shaft 71 being rotatably driven, an agitation blade 72 connected to the rotary shaft 71, and an auxiliary agitation blade 73 provided in the vicinity of the lower end part of the rotary shaft 71. The auxiliary agitation blade 73 provided at the lower part of the agitation blade 72 is arranged upward in the vertical direction to a waste liquid port 63c provided at the bottom 63b of the sedimentation tank 63. The auxiliary agitation blade 73 is constituted of an upper part 73a and a lower part 73b, each having a nearly rectangular plate-like form, and the upper part 73a of the auxiliary agitation blade 73 is connected to the agitation blade 72 in a consecutive form. The upper part 73a is formed to be shorter than the agitation blade 72 in the radial direction of the sedimentation tank 63. The lower part 73b is connected to the upper part 73a in a consecutive form and is formed to be longer than the upper part 73a in the radial direction of the sedimentation tank 63.
