Application of Fenton Reagent in Electroluminescent Materials Wastewater Treatment

The Fenton reagent oxidation method has been applied to experiment on the electro luminescent materials wastewater treatment. The disadvantages of liquid waste, take waste water for example, can be listed as follows: less discharge, out of proportion, complex composition, low PH. After single-factor and orthogonal experiments, the optimum reaction conditions obtained for the reaction time of 1h, PH value of 7, H₂O₂/COD ratio of 1.2, FeSO₄·7H₂O/COD ratio of 2.5, COD_cr dropped to 70 ~ 130 mg / L, removal rate is more than 90%. After treated, the effluent can comply with the Class B of Integrated Wastewater Discharge Standard (GB8978-1996).
