Abstract:Ozonation is an environmentally friendly technology for wastewater treatment. Catalytic ozonation technology, based on generation of hydroxyl radical (·OH) with high oxidizing power by synergistic effect of catalyst and ozone molecules, effectively enhances degradation efficiency of organic pollutants existed in wastewater and becomes one of the promising wastewater treatment technologies with practical application potential. In this paper, basic mechanisms of degradation of organic pollutant by ozonation and catalytic ozonation technology were described in detail, and factors which influence treatment efficiency of pulp mill effluent with ozonation were discussed. Moreover, the recent research progress of the pulping effluent treatment with ozonation and ozonation catalytic ozonation technology was reviewed. The existing problems and future development trends about ozonation of pulp mill effluent were presented.
