摘　　要：通过中试模型对比了单纯臭氧化与催化臭氧化分别与生物活性炭联用深度水处理技术的除污染效能.结果表明,催化臭氧化比单纯臭氧化更能强化生物炭去除有机物.催化臭氧化与生物炭联用具有协同除污染作用,有效降低了生物活性炭的有机物负荷、减轻了生物炭出水有害物质的穿透.催化臭氧化出水中剩余臭氧更少与溶解氧含量更高等对后续生物炭滤池中生物活性的增强有促进作用.In this paper, biological activated carbon （BAC） was respectively combined with ozonation and catalytic ozonation techniques to research the organic micropollutants removal through a pilot scale test .It was showed that catalytic ozonation had higher ability to enhance BAC for organic compounds removal than ozonation alone .In the combined process of cata-lytic ozonation and biological activated carbon , more organic micropollutants were removed in the catalytic oxidation step , reducing the organic load of biological activated carbon , so that the life time of biological activated carbon was extended .There will be positive effect on bio-logical activity because of less residual ozone content and higher oxygen concentration in the effluents of catalytic ozonation process .

关 键 词：有机污染物 生物活性炭 催化臭氧化 剩余臭氧
