Colloid sewage treatment device for shoemaking industry and treatment method thereof

The invention discloses a colloidal sewage treater for shoemaking industry and a treatment method of the colloidal sewage treater. According to the invention, the stirrer I is used for stirring, so that a flocculating agent and flocculent waste agglomerated by particle impurities in colloidal sewage are retained on the filter screen, and preliminary filtration is realized; the electrified metal plate is pushed by the electric cylinder to move downwards, so that the through hole I is opened, and colloidal sewage flows into the electro-adsorption bin through the filter holes and is subjected to secondary filtration; all the aluminum wires are electrically adsorbed to flocculent waste floating in colloidal sewage, so that adsorption treatment is realized; and the colloid sewage is stirred by the stirrer II, so that heavy metal ions and organic matters in the colloid sewage are removed by the chemical treatment agent and light of the ultraviolet spotlight, and then the heavy metal ions and the organic matters are
