  • In this paper, PFS flocculation-membrane separation is applied to treat food oil-containing wastewater. The removal rates of oil, COD, SS and NH3-N are studied by changing conditions of adding amount of PFS, pH value, reaction time, operation temperature and pressure of membrane, and the optimum technological conditions are obtained: the adding amount of PFS is 70 mg/L, pH value 7, reactor time 60 min, operation temperature 40 ℃ and pressure of membrane 0.7 MPa, The removal rates of oil, COD, SS and NH3-N reached 98%, 93%, 92% and above 80%,respectively. The effluent water could reach first class standards of 《National Integrated Wastewater Discharge Standards 》.
