Catalytic ozonation of chemical wastewater by metal component supported silica fibers.

Electrospinning porous silica fiber ( Epsf) prepared by electrospinning as the catalyst carrier, took Co and Zn as bimetallic active components. The bimetallic load-type catalyst was prepared by the equal volume impregnation method, and the technical features of SEM, XRF were used to explore the effect of its application on the degradation effect of chemical wastewater. The results showed that when the mass ratio of the Zn and Co bimetal components in the catalyst was 1 1, its synergistic ozone had a good treatment effect on wastewater. The COD degradation rate of wastewater was 97. 1% within 100 min,and after the catalyst was reused 7 times,the COD degradation rate of wastewater could still reach 79. 1%. [ABSTRACT FROM AUTHOR]
