摘要
介绍了臭氧及催化臭氧氧化技术降解去除废水中有机物的机理,分析了影响臭氧处理制浆废水效果的主要因素。综述了近年来臭氧及催化臭氧氧化技术处理制浆废水的研究进展;指出此领域尚存在的问题,并对未来的发展方向进行了展望。
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 appli- cation potential. In this paper, basic mechanisms of degradation of organic pollutant by ozonation and catalytic ozonation technology were de- scribed 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 ozonatiou and ozonation catalytic ozonation technology was reviewed. The existing problems and future development trends about ozonation of pulp mill effluent were presented.
