The present invention relates to a method and an apparatus for processing an electrolyte solution containing vanadium ions, and performs a charge reaction, a discharge reaction and a reverse charge reaction so that, in the charge reaction, impurities contained in a first electrolyte solution can be removed and, in the reverse charge reaction, impurities contained in a second electrolyte solution can be removed. Therefore, impurities contained in the electrolyte solution containing vanadium ions can be efficiently removed without repeatedly performing, several times, a charging reaction on the electrolyte solution containing vanadium ions. La présente invention concerne un procédé et un appareil de traitement d'une solution électrolytique contenant des ions vanadium, et effectue une réaction de charge, une réaction de décharge et une réaction de charge inverse de telle sorte que, dans la réaction de charge, des impuretés contenues dans une première solution électrolytique peuvent être éliminées et, dans la réaction de charge inverse, des impuretés contenues dans une seconde solution électrolytique peuvent être éliminées. Par conséquent, des impuretés contenues dans la solution électrolytique contenant des ions vanadium peuvent être efficacement éliminées sans effectuer de manière répétée, plusieurs fois, une réaction de charge sur la solution électrolytique contenant des ions vanadium. 본 발명은 바나듐 이온 함유 전해액의 처리 방법 및 장치에 관한 것으로, 충전 반응, 방전 반응 및 역충전 반응을 수행함으로써, 충전 반응에서 제1 전해액에 포함된 불순물을 제거하고 역충전 반응에서 제2 전해액에 포함된 불순물을 제거할 수 있다. 이를 통해, 바나듐 이온 함유 전해액의 충전 반응을 여러 번 반복하지 않고도 바나듐 이온 함유 전해액에 포함된 불순물을 효율적으로 제거할 수 있다.
