<p><P>PROBLEM TO BE SOLVED: To provide an ink waste liquid treatment method which can obtain stable treated water quality by devising a decolonization process and its incorporation and perform efficient treatment easily at a low cost without adding a large amount of chemicals to removed/waste material. <P>SOLUTION: In the ink waste liquid treatment method, after treating ink waste liquid at least by a concentration device capable of inhibiting color components, dilution water from the concentration device is treated by an organic material decomposition device, concentrated water from the concentration device is made to impregnate an absorber, and moisture in a concentrated water-impregnated absorber is evaporated by a drying device. <P>COPYRIGHT: (C)2004,JPO</p> |
