1. a removal method for anode slime of porous anode, is characterized in that:

  • have the porous anode of the anode sludge to be placed in after the anode sludge of acidic reduction agent reduction of dissolved surface surface deposition, water cleans porous anode;

    Described acidic reduction agent is comprised of strong acid and reductive agent;

    Strong acid in described acidic reduction agent is selected from least one in hydrochloric acid, sulfuric acid, nitric acid, and the concentration of acid is 10-200g/L;

    Described reductive agent is selected from oxalic acid, at least one in hydrogen peroxide and ferrous vitriol and halogen, and the concentration of reductive agent is 1-50g/L;

    The process of the described reduction of dissolved surface anode sludge adopts the porous anode with the anode sludge is immersed in acidic reduction agent or by acidic reduction agent and is injected on the porous anode with the anode sludge;

    Described soak time is 20min-12h;

    Described injecting time is 5min-3h, and spraying pressure is 0.5MPa-10MPa.
