氧化还原介体在生物脱色过程中的作用已有较详细的研究，但以氧化还原介体修饰功能性生物载体的生物反应器体系的文献较少。设计了两种不同的生物反应器结构(以分散绿松石蓝S-GL为氧化还原介体的功能载体生物反应器R1和未改性生物载体生物反应器R2)，并对其进行了实验研究。Gyw(EF188281)。通过批量实验对共基质、温度、pH等影响因素进行了优化。与生物反应器R2相比，生物反应器R1对分散大红S具有较好的脱色效果和脱色性能，脱色率较高(当−浓度为0.8gL时脱色率达96%以上)，水力停留时间较短，达到相同的脱色效果。氧化还原介体与生物载体的组合技术是一种新的生物处理理念，是氧化还原介体应用的一大进步。
The effect of redox mediator has been studied in details in the bio-decolorization processes, but there are little literatures about bioreactor systems with functional bio-carrier modified by redox mediator. Two different bioreactor configurations (bioreactor R1 with functional bio-carrier modified by disperse turquoise blue S-GL (as redox mediator) and bioreactor R2 with non-modified bio-carrier) were designed and tested for disperse scarlet S-BWFL decolorization by Halomonas sp. GYW (EF188281) in this study. Influencing factors such as co-substrate, temperature and pH were optimized through batch experiments. Compared to bioreactor R2, bioreactor R1 exhibited good decolorization efficiency and performance ability for the disperse scarlet S-BWFL decolorization, which showed higher decolorization efficiency (over 96% color removal with 0.8gL−1dye concentration) and less hydraulic retention time to attain the same decolorization efficiency. The combinational technology of redox mediator and bio-carrier was a new bio-treatment concept and a great improvement for the application of redox mediator.
