<P>PROBLEM TO BE SOLVED: To provide an organic sludge processing method using an amidine-based polymer flocculating agent including a surfactant, which method suppress the foaming of a dehydrating/separating solution without impairing the flocculation property and dehydration property of organic sludge, prevents the contamination of the surroundings and a drop in sludge processing performance, and enables efficient dehydration processing. <P>SOLUTION: The organic sludge processing method includes adding to organic sludge an alkaline metal salt and/or inorganic coagulant in the form of multivalent anions when the organic sludge is dehydrated using an amidine-based polymer flocculating agent including a surfactant. <P>COPYRIGHT: (C)2013,JPO&INPIT |
