[0022] The working principle and use flow of the utility model are as follows:

[0023] The device body is a tank 1, which is divided into two compartments by a baffle, one of which is an electrolytic tank 11 and the other is an overflow tank 12, and the baffle has an opening of about 5 mm to facilitate overflow of the electrolyte in the electrolytic tank 11 to the overflow tank 12. The electrolytic tank 11 is provided with electrodes (an anode 2 and a cathode 3), and when the device is running, a certain amount of brown waste liquid is first added to the electrolytic tank 11 and the overflow tank 12, and then the magnetic pump 5 is started to circulate, the magnetic pump 5 delivers the electrolyte in the overflow tank 12 back to the electrolytic tank 11 through the filter 5, and finally flows from the electrolytic tank 11 to the overflow tank 12. During the electrolysis process, the anode 2 and the cathode 3 undergo the following reactions:

[0024] Cathode: Cu 2+ + 2e - = Cu;
