<P>PROBLEM TO BE SOLVED: To provide a coagulation sedimentation apparatus capable of suppressing deposition of a polluted mud on a flow blocking plate and occlusion of a blowing out port. <P>SOLUTION: In the coagulating sedimentation apparatus 1, the suspended substances and coagulated flocks of water to be treated are sedimented and separated in a sediment tank 10, and a slurry blanket layer is formed and the water are clarified. The coagulating sedimentation apparatus has: a chamber 12 which is arranged in the sediment tank 10 and into which the water is introduced; a distributer 14 which is rotatably arranged in the lower end part of the chamber 12 and which has a blowing out pipe 20 in which a blowing out port 22 for blowing out the water in the chamber 12 to the lower side in the sediment tank 10 is formed; the flow blocking plate 16 arranged in the lower side of the blowing out port 22 and rotating along with the distributer 14; and a deposition suppressing unit 18 fixed in the sediment tank 10 so as to pass through between the blowing out port 22 and the flow blocking plate 16. <P>COPYRIGHT: (C)2013,JPO&INPIT |
