LiF-doped TiO2 had been prepared in sol-gel method ,its diameter was about 20~30nm, the contents of anatase nano TiO2 were more than 80%.Influence of several factors were studied for molasses alcohol waste water degradation by ultrasonic cavitation. The results show that the decolorization rate of molasses alcohol wastewater reached 99% by using TiO2 and ultrasound under the following conditions: ultrasonic frequency 40kHz,ultrasonic power 50W,amount of TiO2 950mg-L, temperature 20℃, initial concentration of CODchemical oxygen demand 500mg-L, ultrasound irradiation time 45min.
