Rotor-stator reactor (RSR) was employed in tandem with bubble column reactor (BCR) to enhance Acid Red 73 (AR73) degradation by ozonation in a simulated dyeing wastewater in this work. It was found that AR73 and COD degradation efficiencies of more than 97 % and 30 % respectively were achieved in the O₃/RSR-BCR process. Due to the excellent mass transfer effect of RSR, AR73 degradation efficiency in the O₃/RSR-BCR process was significantly higher than that in the O₃/BCR process, exhibiting the effect of lowered ozone consumption as well as reduced BCR volume as a result of shorter liquid residence time. The advantages of the O₃/RSR-BCR process for AR73 wastewater treatment were attributed to the high O₃ absorption efficiency in RSR and relatively long reaction time of O₃ with pollutants in BCR. The results demonstrated that the O₃/RSR-BCR process can be an efficient decolorization technique in dyeing wastewater treatment.

在这项工作中，将转子-定子反应器（RSR）与鼓泡塔反应器（BCR）串联使用，以通过臭氧化作用增强酸红73（AR73）的降解。发现在O ₃ / RSR-BCR工艺中，AR73和COD的降解效率分别达到97％和30％以上。由于RSR具有出色的传质效果，因此O ₃ / RSR-BCR工艺中的AR73降解效率明显高于O ₃ / BCR工艺中的AR73降解效率，具有降低臭氧消耗以及降低BCR体积的效果。缩短液体停留时间的结果。O ₃ / RSR-BCR工艺处理AR73废水的优势归因于高O ₃BSR中RSR的吸收效率高，O ₃与污染物的反应时间相对较长。结果表明，O ₃ / RSR-BCR工艺可以作为印染废水处理的有效脱色技术。
