| Abstract: | The catalytic ozonation nanometer TiO2-loaded activated carbon is prepared by precipitation-absorption method.The ozone with TiO2-loaded activated carbon is applied to chloroacetic acid wastewater treatment.The effect of ozonation time,pH value and ozone concentration on the treatment of chloroacetic acid by catalytic ozonation is studied in this paper.Experimental results suggest that chloroacetic acid wastewater can be effectively disposed and the removal of COD can reach 85%. |
