Study on Treatment of Polyvinyl Alcohol in Water by Ozone Catalytic Ozonation

Abstract:

The paper has studied the degradation effect of the polyvinyl alcohol in the Ozone catalytic oxidation oxygenated water, include three kind of catalyst of Fe2+, Mn2+, Cu2+. The results as below, the degradation effect of the polyvinyl alcohol by Ozone catalytic oxidation is higher than ozone alone obviously, and it is related with the concentration of catalyst, the degradation effect will increase with the increase of concentration of Fe2+, and to the maximum value, the degradation is 85%; it will decrease with the increase of concentration of Mn2+, the optimum content is about 5mg/L, the degradation rate is 85%; when Cu2+ is added, the degradation rate is 53% in 35mg/L, and the degradation of other contents is not obvious. When the content of three kinds of catalyst are all 35mg/L and the reaction time is 3h, the sort of degradation effect is Fe2+>Cu2+>Mn2+.
