Abstract:
By mak ing use of titanium d iox ide film and activated carbon fibre ( T iO2 /ACF), 254 nm UV- ray w as used as the light sources to decompose photocata ly tica lly aqueous pheno l so lution of 40m g /L over T iO2 film, thus the pho tocatalytic e ffect of pheno lw as ana lyzed. The result show ed that the designed and m ade pho to ca talytic reacto r optim ized hydrodynam ic conditions w as and streng thened the u tiliza tion of illum inan t, and that under dynam ic cond ition, fivem ain factors tha t impacted pho to ca talytic degradation e ffects of TiO2 /ACF were stud ied, nam e ly, pH, pow er of u ltrav io let, ve lo city o f w ater wa ter, HRT, and concentra tion of oxygen. It was found that the T iO2 film exh ib ited a degrada tion e ffic iency of 91% for pheno land a remova l rate o f 79% for COD after 7. 67 h, w hile the condition of pH = 7. 5, the concentration o f pheno l is 40m g /L, pow er of u ltrav iolet light is 1. 75W /L, and a ir quantity is 2. 6 mL/ ( m in? L) .
