A study on degradation of aniline by combined nano-TiO_2-fly ash/UV and ozone

The wastewater containing aniline was treated by the method combined nano TiO2-fly ash/UV and Ozone,and the effect of reaction time,pH value,catalyst dosage,light intensity,temperature and the loading times were discussed.Experimental results showed that when initial concentration of aniline was 100 mg/L,pH value was 7.0,temperature was(20±2)℃ and the layers of TiO2 were 4,the removal rate of aniline can reach 97% when the light time is 8 min.
