Abstract

PURPOSE: To permit the continuous operation of centrifugal dehydrator, improve the releasing of wet cake and prevent the abmormal vibration of the dehydrator by using a means in which a high molecular coagulant is beforehand added to coke powder-containing fine sludge particles and lower the moisture content of wet cake.
CONSTITUTION: The waste water A from each place of an iron works is concentrated in the thickener 1, and the separated sludge is supplied with the converter sludge B to the sludge tank 2 where 5W100ppm (as coagulant) of a coagulant solution containing a high molecular coagulant C is added to coke powder-containing fine sludge particles, whereby the fine particles are coagulated by cross-linking. Then, the fine particles are subjected to centrifugal dehydration. Thus, the moisture content of the wet cake D can be lowered and also the releasing of the cake can be improved, thus eliminating the abnormal vibration of the centrifugal dehydrator and permitting the continuous operation of the dehydrator.
