ELECTROLYTIC REGENERATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electrolytic regeneration device capable of being reduced in size and furthermore decreased in bath volume.

SOLUTION: A regeneration unit 19 includes: a tubular portion 23 having an inner circumferential surface functioning as an anode; and a cathode 25 provided inside the tubular portion 23 and extending along the extension direction of the tubular portion 23 while being separated from the inner circumferential surface 31. A treatment liquid used for desmear treatment is fed through a gap between the inner circumferential surface 31 of the tubular portion 23 and the cathode 25. A feed-side conduit 15 is connected by a downstream end portion 15b thereof to the tubular portion 23 and guides the treatment liquid discharged from a desmear treatment tank 13 into a regeneration unit 19. A return-side conduit 17 is connected by an upstream end portion 17a thereof to the tubular portion 23 and guides the treatment liquid discharged from the regeneration unit 19 into the desmear treatment tank 13.
