The present invention relates to an electrolyzer for recovering valuable metal, wherein valuable metal contained in wastewater such as metal waste water, washing liquid used in a plating process, leachate solution of ores, leachate of scraps, and the like can be recovered swiftly and precisely by increasing a specific contact surface area between a cathode and an anode. The electrolyzer for recovering valuable metal, which has a cathode and an anode corresponding to each other and recovers recyclable valuable metal by electro-depositing the valuable metal from wastewater containing plating wastewater or valuable metal via electrolysis, comprises: a housing having an inlet for introducing wastewater in one side, an outlet for discharging wastewater in the other side, and an inner space; multiple cathodes installed in zigzag at regular intervals while dividing the inner space of the housing in a longitudinal direction; multiple anodes installed between the cathodes and installed in zigzag to classify spaces between the adjacent cathodes as multiple spaces for recovering valuable metal; and a filling material which is a conductive material, is filled in the spaces for recovering valuable metal, has multiple gaps to allow the wastewater to pass through. |
