•AR73和COD的降解效率分别达到97%和30%以上。

•O3/RSR- bcr工艺的优势在于RSR具有良好的传质效果。

•通过自由基do和O3攻击AR73中的偶氮显色基团实现脱色。

摘要

采用转子-定子反应器(RSR)与泡柱反应器(BCR)串联处理模拟印染废水，提高臭氧氧化对酸性红73 (AR73)的降解效果。结果表明，O3/RSR-BCR工艺对AR73和COD的降解效率分别达到97%和30%以上。由于RSR优良的传质效果，O3/RSR-BCR工艺对AR73的降解效率显著高于O3/BCR工艺，表现出由于液体停留时间缩短而降低臭氧消耗和减小BCR体积的效果。O3/RSR-BCR工艺处理AR73废水的优势在于RSR中O3的吸附效率高，BCR中O3与污染物的反应时间相对较长。结果表明，O3/RSR-BCR工艺是一种高效的印染废水脱色技术。

Ozone equipment

The ozone generator (3S-A10, Tonglin Technology Co., LTD., China) generates ozone from the air, and the ozone concentration analyzer (3S-J5000, Tonglin Technology Co., LTD., China) monitors the concentration of gaseous ozone. The ozone-containing gas enters the RSR through the gas inlet and flows radially inward. When the O3 concentration in the airflow reaches a stable level, the AR73 solution is pumped into the RSR through the liquid inlet and flows radially outward under the action of the centrifugal force generated by the rotating rotor.
