Treatment of phenol wastewater by microwave-induced CIO_2-CuO_x/Al_2O_3 catalytic oxidation process

The catalyst of CUOx/Al2O3 was prepared by the dipping-sedimentation method using y-Al2O3 as a supporter. CuO and Cu2O were loaded on the surface of Al2O3, characterized by X-ray diffraction （XRD） and X-ray photoelectron spectroscopy （XPS）. In the presence of CuOx/Al2O3, the microwave-induced chlorine dioxide （ClO2） catalytic oxidation process was conducted for the treatment of synthetic wastewater containing 100 mg/L phenol. The factors influencing phenol removal were investigated and the results showed that microwave-induced C102-CuOx/ml203 process could effectively degrade contaminants in a short reaction time with a low oxidant dosage, extensive pH range. Under a given condition （ClO2 concentration 80 mg/L, microwave power 50 W, contact time 5 latin, catalyst dosage 50 g/L, pH 9）, phenol removal percentage approached 92.24%, corresponding to 79.13% of CODcr removal. The removal of phenol by microwave-induced ClO2-CuOx/Al2O3 catalytic oxidation process was a complicated non-homogeneous solid/water reaction, which fitted pseudo-first-order by kinetics. Compared with traditional ClO2 oxidation, ClO2 catalytic oxidation and microwave-induced ClO2 oxidation, microwave-induced ClO2 catalytic oxidation system could significantly enhance the degradation efficiency. It provides an effective technology for the removal of phenol wastewater.
