| 摘 要： | 以超重力旋转填充床(RPB)作为反应装置,研究了Fe2+离子作为催化剂的情况下,臭氧高级氧化技术处理酸性红B染料废水的效果.考察了旋转床转速、PH值、Fe2+离子浓度、气体流量和液体流量等因素对脱色率的影响.实验表明,在酸性条件下均相催化臭氧化方法的脱色率明显高于臭氧单独处理,酸性红B的脱色率随着转速的增加而增加.当R...

| Abstract: | In a reactor of the rotating packed bed(RPB),the decolorization of dye waste water with Acid Red B by homogeneous catalytic ozonation was explored with Fe~(2+)as the catalyst.Effects of rotating speed,liquid pH, Fe~(2+)concentration,gas flow rate and liquid flow rate on the decolorization of Acid Red B were investigated.The results showed that the efficiency of ozonation decolorization with homogeneous catalyst was much better than that without catalyst.The decolorization of Acid Red B increased with increa... |
