A study on the advanced treatment of pulp and paper wastewater by ozone oxidation

The processing conditions of advanced treatment of pulp and paper wastewater by ozone oxidation were studied, including the relationship between the ratio of content of ozone and wastewater and the treatment effect, the effect of the reaction time to the treat efficiency and the mechanism of ozone bleaching. The result showed that removal rate of CODCr and color in wastewater can up to more than 80% and 93% respectively when contact time 5min,pH 8, and ozone concentration 42.55mg/L. So we can come to the conclusion the index of the wastewater treated by ozone bleaching can up to new discharge standard of pulp and paper wastewater.
