Zusammenfassung:	The invention discloses a waste electrolyte treatment method. The method comprises the following steps of a, treating waste electrolyte to obtain a primary copper-removed finished solution with a copper ion concentration of 35-45g/L, b, treating the primary copper-removed finished solution by a continuous electrowinning method utilizing an insoluble anode and a stainless steel cathode to obtain A-level copper and a secondary copper-removed finished solution, and c, treating the secondary copper-removed finished solution by the continuous electrowinning method utilizing an insoluble anode and an electrolysis remnant pole as a cathode to obtain electro-deposited copper, a black copper plate, black copper powder and black copper mud. The invention also provides a waste electrolyte treatment device. The method utilizes the primary copper-removed finished solution with low copper ion content as a raw material, the insoluble anode and the stainless steel cathode to produce the A-level copper so that a production cost is reduced and resource waste is reduced.
