<p><P>PROBLEM TO BE SOLVED: To provide a treatment apparatus for reduction of sludge which can perform a stable electrolysis by increasing flow speed of sludge in an electrolytic cell while securing electrolysis time in the cell, without causing precipitation of sludge, nor clogging in the cell. <P>SOLUTION: This apparatus is equipped with a biological treatment tank 6 biologically treating organic sewage; a conditioning tank 1 conditioning surplus sludge A from the tank 6 by adding a salt F and acid E thereto; the electrolytic cell 2 electrolyzing sludge B from the tank 1; and a circulation passage 5 for returning sludge C electrolyzed in the cell 2 to the tank 6, and returning a part of sludge D electrolyzed in the cell 2 to the cell 2 by drawing out of the cell 2. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
