Preparation of Mn/Zn@PG Catalyst for Catalytic Oxidation Treatment of Coal Chemical Wastewater

Mn/Zn@palygorskite catalysts with improved pores and good salt tolerance were produced and used for the treatment of coal chemical wastewater in this study. According to the Mn/Zn@PG catalyst's ZnO and MnO2, respectively, the ZnO and MnO2 elements existed as ZnO and MnO2. The following are the optimal working conditions of the Mn/Zn@PG catalyst for catalytic oxidation treatment of coal chemical wastewater, which were obtained by the optimization of working conditions: reaction time 60 min, wastewater pH = 9. 28, ozone ventilation rate 0. 2 L/min, catalyst filling ratio 20% The Mn/Zn@PG catalyst's abrasion resistance and catalytic results were investigated after repeated use, and the mechanism of the Mn/Zn@PG catalyst's loss of active components of the Mn/Zn@PG catalyst was investigated. To determine the catalytic ozonation reaction of coal chemical wastewater, the hierarchicalu2013principal component comprehensive evaluation system was developed, so that the overall evaluation of the process results can be carried out.
