摘要

将微气泡臭氧化技术与UV照射相结合强化处理酸性大红3R废水,分析了UV强化微气泡臭氧化过程中的臭氧气液传质、酸性大红3R废水脱色和TOC去除效果。结果表明,UV强化微气泡的臭氧传质系数和分解系数分别为单独微气泡臭氧时的1.6、1.2倍。UV强化微气泡臭氧处理酸性大红3R废水的脱色速率常数为0.185 min~(-1),为单独微气泡臭氧处理的1.2倍。TOC去除反应速率常数为0.0255 min~(-1),为单独微气泡臭氧的1.6倍;TOC去除臭氧反应效率为0.1868 mg/mg,为单独微气泡臭氧的1.3倍。
        Enhanced treatment of Acid Scarlet 3R wastewater has been implemented by the combination of microbubble ozonation technology with ultraviolet(UV) irradiation. The ozone gas-liquid mass transfer,decolorization of Acid Scarlet 3R wastewater and TOC removing effect in the UV enhanced micro-bubble ozonation process have been analyzed. The results show that the ozone mass transfer coefficient and decomposition coefficient of UV enhanced micro-bubbles are l.6 times and 1.2 times of those by single micro-bubble ozonation,respectively. The decolorization rate constant of Acid Scarlet 3R wastewater treated by UV enhanced micro-bubble ozonation is 0.185 min~(-1),which is 1.2 times of that by single micro-bubble ozonation treatment. The removing reaction rate constant of TOC is 0.0255 min~(-1),which is 1.6 times of that treated by single micro-bubble ozonation. The ozone removing reaction rate of TOC is 0.1868 mg/mg,which is 1.3 times of that treated by single micro-bubble ozonation.
