This invention belongs to the field of metal refining processes and provides a parallel flow copper electrolytic refining process. The process involves setting up a balance tank outside the copper electrolytic cell, with crude copper anode plates and stainless steel cathode plates alternately arranged inside the cell and guided by flow guides. A cathode-wall flow channel is formed between the flow guides and the cell wall. Slit nozzles are set on the flow guides along the length of the cell, allowing the electrolyte to be sprayed from the cell side onto the cathode surface and form a parallel flow along the cathode wall. An anode collecting tank is set at the bottom of the copper electrolytic cell. A hydrodynamic barrier is constructed by adjusting the pressure difference between the cathode-wall flow channel and the anode collecting tank, inhibiting the migration of anode sludge to the cathode. The impurity-rich electrolyte from the anode collecting tank is introduced into an online impurity removal unit for treatment and then returned to the balance tank. After mixing with the electrolyte in the cathode circulation branch, it re-enters the cathode-wall flow channel, thereby obtaining cathode copper with uniform composition and controlled impurities.
