Treatment method of aluminum profile wastewater

The invention discloses a treatment method of aluminum profile wastewater, the treatment method comprises the steps of adding a modified adsorbent for precipitation and adding a composite precipitant for re-precipitation.By optimizing the components and proportion of the modified adsorbent and the composite precipitant, a remarkable sewage treatment effect can be achieved; the treated wastewater can be recycled, so that the treatment cost is reduced; specifically, in the modified adsorbent, zeolite and carbide slag are treated by a first modifier, so that the adsorption performance and ion exchange performance are improved, the crystallinity of chitosan treated by a second modifier is reduced, the flocculation effect of the chitosan can be obviously improved, and after the modified adsorbent is treated, a composite precipitator is added, so that the flocculation effect of the chitosan is improved. And flocculation and precipitation are further performed, so that the turbidity of the aluminum profile can be re
