<p>A coagulating sedimentation processing apparatus comprising a sedimentation tank, a mixing chamber rotatably supported within the sedimentation tank, means for supplying suspension and additive to the mixing chamber, a mixer arranged within the mixing chamber for stirring mixed liquid of the suspension and the additive, and a plurality of distributors extending radially from the mixing chamber and provided with a plurality of jetting ports which open downwardly, wherein strip-like baffle plates are fixedly mounted respectively below the distributors so as to be opposed against the jetting ports. The mixing liquid jetted downwardly from the jetting ports of the distributor impinges against the baffle plate and is buffed so that its velocity head is reduced. Accordingly, there is no case where turbulent flow is generated by the mixing liquid which is jetted to the concentrated sludge layer which is formed in a bottom of the sedimentation tank.</p> |
