Influence parameters in the ozonation of phenol wastewater treatment using bubble column reactor under continuous circulation

다국어 초록 (Multilingual Abstract)

The ozonation of phenol wastewater treatment system has been investigated with effective mass
transfer between gas and liquid phase in a bubble column reactor. The designed bubble column reactor
was investigated for increasing the rate of mass transfer of ozone, the rate of oxidation of phenol in the
solution, the solubility and decomposition rate of ozone in the distilled water were also studied at
different flow rates. The decomposition rate constants were calculated based on pseudo first order
kinetics. The oxidation of phenol was investigated in order to provide the overall reaction rate constant
for the reaction between ozone and phenol at 25℃. The influence of the operating parameters like initial
phenol concentration, ozone flow rate and pH for the destruction of phenol by ozonation were studied.
The pseudo first order rate constant was depending on the initial concentration of phenol solution. A
comparison of TOC removal percentage between bubble column reactor and bubble diffuser using
ozonation were reported.
