Zusammenfassung:PROBLEM TO BE SOLVED: To provide an easy method for processing a waste cleaning water for increasing the flocculation effect of a flocculation process on a waste cleaning water generating in a developing process of a photosensitive planographic printing forme and for increasing filtration characteristics on the flocculated waste cleaning water. SOLUTION: The method for processing a waste cleaning water generating in a developing device for a photosensitive planographic printing forme includes: (1) adding a cationic polymer flocculant to the waste cleaning water; (2) then adding an anionic polymer flocculant; and (3) filtering the waste water.
