<p>The present invention relates to an electrolytic bath which is configured so as to effectively electrodeposit recyclable valuable metals from electroplating waste water or waste water containing valuable metals to recover the same, and more specifically, to an electrolytic bath for recovering valuable metals, with an increased contact specific surface area wherein the specific surface area of an electrode to be in contact with waste water to be electrolyzed is maximized to increase electrolysis efficiency, and an electrolysis space is increased to enable the effective electrode position and recovery of valuable metals even from a low concentration of waste water. The electrolytic bath of the present invention electrodeposits valuable metals contained in waste water by electrolysis with a cathode and an anode to recover the same, and comprises: a housing where an inlet, an outlet and a gas discharge hole are formed and has an inner space; an anode group which comprises a plurality of anodes installed with encompassing the inner space; and a cathode group which is installed between the anode and the anode with encompassing the inner space to divide into two electrolysis spaces and where a bundle of cathode wire threads is placed at one side of each electrolysis spaces, thereby increasing the specific surface area to be in contact with waste water. Valuable metals are electrodeposited to the cathode group comprising a bundle of cathode wire threads to be recovered when waste water flown through the inlet passes through a plurality of the electrolysis spaces in turns, and the recovered valuable metals are discharged outside through the outlet when gas is discharged through the gas discharge hole.</p> |
