摘要

TiO2 photocatalytic film was coated on the disk surface of the SDR (spinning disc reactor) by sol-gel method, and then used to degrade phenol wastewater. The effects of different solvents, amount of water and inhibitors on the gelation time were investigated. The optimal ratio of raw material for film preparation was obtained: n(titanium):n(water):n(ethanol):n(hydrochloric acid):n(acetic acid)=1:2:13.56:0.05:1. The synthesized TiO2 thin film was characterized by SEM, XRD and the results showed that the loaded catalyst was uniform anatase TiO2. The degradation rate and mineralization rate of phenol wastewater were studied under four different conditions: oxidation degradation by H2O2, UV/H2O2, UV/TiO2 and UV/H2O2/TiO2. The results showed that phenol was almost degraded completely by H2O2/TiO2 after 30 minutes, and its degradation time was 30 minutes shorter than UV/H2O2. The degradation rate increased greatly compared with that in UV/TiO2. Moreover, the mineralization rate in UV/H2O2/TiO2 was 89%, which was about 28% higher than that in UV/H2O2.
