Abstract

PURPOSE: To recycle washing waste water and efficiently recover valuable metal contained by regenerating primary washing water of a pickled or plated metal in an electrodialytic vessel and regenerating secondary washing water in an electrodialytic vessel and an electrolytic cell.
CONSTITUTION: Pickled copper wire 10 is subjected to primary and secondary washing. Primary washing water W1 is used for repeated washing of wire 10 to raise the copper ion concn. and circulated to deionization chamber dil of electrodialytic vessel EDS 1 to be deionized, lowering the copper ion concn. from 3,000 ppm to 2,000ppm. On the other hand, conc. liquor W2 in tank 12 is circulated to concn. chamber con of EDS 1 to raise the copper ion concn. and electrolyzed in pickling liquid vessel 13 to recycle the liquor as a pickling liquid as well to recover copper. Secondary washing water W3 is used for repeated washing of wire 10 to raise the copper ion concn., treated in electrodialytic vessel EDS 2 to lower the concn., electrolyzed in electrolytic cell ET set in paralle with EDS 2 to recover copper and thus lower the copper ion concn., and used as secondary washing water again.
