Photocatalytic oxidation of humic acid in micro pollution water with catalyzer TiO₂

How to deal with the humic acid of micro pollution water with photocatalytic catalyzer TiO2 was analyzed.The water samples were treated by TiO2 and UV ray.The impacts of pH,TiO2 concentration,the initial concentration of humic acid,aeration intensity and air temperature on humic acid degradation effect were discussed.The results show that the organic degeneration rate can reach 96.83% if pH value is 3.5,TiO2 concentration reaches 1.0 g/L,aeration intensity is 0.12 m3/h and air temperature becomes 18 ℃.According to the mentioned-above,the method of photocatalytic catalyzer TiO2 can degrade humic acid of micro pollution water efficiently.
