首次采用一种新型泡沫搅拌多相槽反应器（RFSR）强化臭氧传质和氧化处理合成纺织废水。结果表明，RSFR可以通过调节操作条件和气体流体力学来改善臭氧的传质过程。为了预测体积传质系数，建立了一组偏差在±15%以内的关联式。以酸性红B（AR B）溶液为模拟合成纺织废水，通过强化臭氧传质过程提高了去除率，改变操作条件可促进臭氧氧化途径向间接反应方式转变。最后，研究结果表明，铁钴氧化物涂层的泡沫块搅拌器可以进一步强化降解过程中的ARB溶液。本研究对RFSR的强化机理有了初步的认识，展示了RFSR在废水处理中的良好前景。
A novel multiphase tank reactor with foam block stirrer, also called rotating foam stirrer reactor (RFSR), was used to intensify ozone mass transfer and oxidation of synthetic textile wastewater processes for the first time. Results show that the RSFR can improve the ozone mass transfer process by adjusting operation conditions and gas hydromechanics. In order to predict the volumetric mass transfer coefficient, a set of correlation was developed within ±15% deviation. Further, based on an Acid Red B (ARB) solution used as simulated synthetic textile wastewater, it was found that the removal efficiency was improved by intensifying ozone mass transfer process, and changing operation conditions can promote the transformation of the ozone oxidation path to an indirect reaction way. Finally, results show that the Fe-Co oxides coated on the foam block stirrer can further intensify the degradation processes in the ARB solution. This study gives a fundamental understanding of the intensification mechanism of the RFSR and shows the promising prospect of an RFSR used in in the wastewater treatment.
