Catalytic decomposition and mass transfer of aqueous ozone promoted by Fe-Mn-Cu/γ-Al2O3 in a rotating packed bed
文献摘要：
This study investigated catalytic decomposition and mass transfer of aqueous ozone promoted by Fe-Mn-Cu/γ-Al2O3(Cat)in a rotating packed bed(RPB)for the first time.The results showed that the value of the overall decomposition rate constant of ozone(Kc)and overall volumetric mass transfer coefficient(KLa)are 4.28×10-3 s-1 and 11.60×10-3 s-1 respectively at an initial pH of 6,β of 40,Co3(g)of 60 mg·L-1 and QL of 85 L·h-1 in deionized water,respectively.Meanwhile,the Kc and KLa values of Fenhe water are 0.88×10-3 s-1 and 2.51×10-3 s-1 lower than deionized water,respectively.In addition,the Kc and KLa values in deionized water for the Cat/O3-RPB system are 44.86％and 47.41％higher than that for the Cat/O3-BR(bubbling reactor)system,respectively,indicating that the high gravity technology can facilitate the decomposition and mass transfer of ozone in heterogeneous catalytic ozonation and provide some insights into the industrial wastewater.
