摘要:
Adsorption performance of catalysts and catalytic ozonation of organic pollutants from bio- treated dyeing wastewater were investigated. Among various catalysts, the granular activated carbon (GAC) showed the better adsorption performance for removal of COD from dyeing wastewater, and the adsorption capacity was 2.1 mgCOD/gGAC. In addition, Mn@GAC composite catalyst was prepared by an impregnation method and used for catalytic ozonation. The XPS results showed that Mn was located onto GAC surface in the form of MnO2. The catalytic ozonation for COD removal efficiency was 41.7% with Mn@GAC. Therefore, the Mn@GAC catalytic ozonation is feasible for removal of the refractory organic pollutants from the dyeing wastewater.
