Abstract Catalytic ozonation is an effective method for the treatment of phenolic wastewater. In order to study the
degradation efficiency of phenolic wastewater by α-Fe O catalytic oxidation and effectively recover the catalyst,
2 3
micron-sized α-Fe O catalytic ozonation was applied to the simulated phenol wastewater, and the catalyst dispersed
2 3
in the reaction system was intercepted and recovered by the ceramic membrane to realize the continuous operation
of the process. The results showed that: Under the condition of intermittent operation, COD removal rate of
wastewater reached more than 97% after catalytic oxidation reaction for 30 min. The main reason for the high COD
removal rate was that α-Fe O had strong catalytic activity for ozone and strong oxidizing product ·OH was
2 3
produced during catalytic oxidation.Under the condition of constant pressure, R accounted for more than 50% of the
r
total resistance, which was verified by membrane fouling model fitting and series resistance model. However, when
the operating pressure exceeded 30 kPa, some reversible fouling gradually transformed into irreversible fouling, and
R increased significantly. The formation mechanism of membrane fouling was explored by kinetic fitting. The
ir
ceramic membrane fouling model during operation was intermediate blockage or filter cake blockage. Membrane
fouling mainly occurred on the membrane surface. The membrane could effectively intercept α-Fe O and recover
2 3
the flux through backwashing. During the six-cycle operation of continuous influent, COD removal rate of simulated
wastewater remained above 85%, the irreversible resistance of ceramic membrane was controlled below 13% of the
total resistance, and the reaction system maintained stable operation.
