Study on catalytic oxidation of organic micro-pollutants in source water enhanced by water-lifting aerator
The supported catalysts RuO2-CeO2/γ-Al2O3,Fe2O3- CeO2/γ-Al2O3,Fe2O3/γ-Al2O3 were prepared by consecutive impregnation in which γ-Al2O3 was used as carrier.The catalysts were applied to treat organic micro-pollutants in source water from a reservoir in Xian under conditions of water lifting and aeration.No obvious inactivity phenomenon was found,even if the catalysts were constantly used for 20 days to eliminate effect of pure adsorption,38% of UV254,28% of CODMn and 27% of TOC can be removed in 7 days.The result of leaching ions tests shows the catalyst Fe2O3/γ-Al2O3 has an excellent stability,thus it was chosen as optimum catalyst considering treatment effect,preparing process and preparing cost.Then the roasting temperature,roasting time,and dipping solution concentration were investigated to optimize preparing process of Fe2O3/γ-Al2O3.
