Abstract：

The process of anaerobic-Anoxic-Oxic(A2O) effluent from coking plant was pretreated by the Fenton regent and microfiltration.The effects of oxidation on the water quality and membrane fouling were investigated. The experiment results showed that the removal rate of the COD and mineral oil were above 70%, the removal rate of UV254 was 47%, and the removal rate of turbidity and suspended solids were above 80%. The resistance of membrane filtration decreased by 92.1% and the membrane fouling was controlled effectively.
Key words: Fenton oxidation, PES membrane, dead-end filtration, cake layer resistance.
