| Zusammenfassung: | The invention relates to the technical field of anodic oxidation wastewater treatment, in particular to an aluminum profile anodic oxidation wastewater treatment process. During use, wastewater generated in the anodic oxidation production process is collected, the pH value of the wastewater is adjusted to 2.5-3.2, electric flocculation treatment is carried out, then hydrogen peroxide is added into the wastewater to carry out Fenton advanced oxidation reaction with ferrous ions generated by electrolysis, then the pH value of the wastewater is adjusted to 3.3-4.1, standing, precipitation and separation are carried out, supernate is taken, the pH value is adjusted to 8-9, standing, precipitation and separation are carried out, supernate is taken , and sequentially filtration treatment, ultrafiltration treatment and reverse osmosis treatment are performed to obtain reuse water; and compared with a traditional anodic oxidation wastewater treatment process, the aluminum profile anodic oxidation wastewater treatment |
