ABSTRACT
In this paper, ozone advanced oxidation technology was used to degrade the simulated acidic red GR and activated red X-3B wastewater. The treatment conditions were optimized, and ozone advanced oxidation was expanded with other technologies. The main conclusions as follows: when alone ozone was used to treat acid red GR dye wastewater, the removal rate reached 95.4% at pH 6-8, and the best degradation effect was achieved by ozone/UV coupled treatment technology, with 99.8% removal rate at pH 7. The treatment of reactive red X-3B by ozone advanced oxidation technology showed the highest removal rate of 97.13% at pH of 8, and the removal rate of ozone/UV coupled treatment technology was up to 99.95% at pH 7. The experiments of ozone-coupled metal catalyst show that the order of treatment effect as follow TiO2 > MnO2 > Fe2O3.
