The invention discloses a multistage electrolysis method, which comprises the following steps: firstly, assembling an electrode plate mechanism; secondly, installing a guide plate; thirdly, connecting the electrode plate mechanism with the tank body; fourthly, injecting electrolyte; and fifthly, electrolyzing the hexavalent uranium solution to form a tetravalent uranium solution. The method has the advantages of simple steps, reasonable design, low cost and convenient and fast electrolysis process operation, the hexavalent uranium solution is formed into the tetravalent uranium solution through multi-stage electrolysis, a plurality of electrode polar plates are isolated and completely isolated from the wall plate of the electrolytic cell, the short circuit of the electrode polar plates is avoided, and the safety and reliability are high. |
