The present invention includes an electrolytic bath with increased contact specific surface area configured to effectively electrodeposit valuable metals from waste water, wherein the specific surface area of an electrode contacting the waste water is maximized to increase electrolysis efficiency, and electrolysis space is increased to enable effective electrodeposition and recovery of valuable metals from low-concentration waste water. The electrolytic bath comprises: a housing having an inlet, outlet, gas discharge hole, and inner space; an anode group comprising a plurality of anodes installed in the inner space; a cathode group installed between the anodes to form two electrolysis spaces, and cathode wire threads placed on one side of each electrolysis spaces. As waste water flows through the inlet and electrolysis spaces and then is discharged through the outlet, metal is electrodeposited onto the cathode group and gas is discharged through the gas discharge hole. |
