摘要

A simulation program is described, tested and used, to predict the micropollutant removal in an ozonation bubble tower with or whitou hydrogen peroxide addition To compute the removal efficiency we need to know the chemical reactivity between organic compounds and oxidant species (molecular ozone and hydroxy radicals), the ozone mass transfer from the gaseous phase to the liquid phase (kLa) and the hydrodynamic model describing the reactor. In this case, we divide the reactor into three parts (water arrifval, air arrival and intermediate zones). Each part is modelled using completely stirred tank reactors in series (C.S.T.R.).
