Abstract

PURPOSE: To continuously perform the separation and concentration of sludge from waste water through a single apparatus, by providing a sludge conveying concentrator at a sludge pocket of a sludge sedimentation vessel.
CONSTITUTION: The sludge is separated from the waste water in the sedimentation vessel 1 and sinks into the sludge pocket 2. The sludge is propelled through a casing 3 by a spiral blade 5. At that time, the grains of the sludge are rearranged so that the solid and liquid of the sludge are separated from each other. After the sludge is transferred into a pipe 6 of smaller inside diameter than the casing 3, the sludge is compressed further in the vertical part of the pipe 6 so that the separation of the solid from liquid of the sludge is accelerated. Because the pipe 6 extends upward above the sedimentation vessel 1, the sludge is removed of water when the sludge is pushed from the upper end of the pipe 6 into a mesh screen 7. Therefore, the sludge can be concentrated without using a separate concentrator.
