The observation of SEM, EDAX and IR analysis showed that the conformation of MPPE was changed, the surface and section of MPPE were rough and accidented, the specific surface area of MPPE was increased, and magnetic powders, HAP and other additives were separated in polyethylene polymer. The removal rates of Phenol by using PPE and MPPE were 82％, 93％, the removal rates of TOC could reach 78％, 89％ respectively, when the phenol wastewater at 120mg/L concentration was treated with aerated process for 14 hours. The removal rates of Phenol were 85％, 90％, the removal rates of TOC reached 80％, 86％ respectively when the phenol wastewater at 350mg/L was treated for 35 hours. The weight of biofilm formation on MPPE was 64％ and 34％ higher than that on PPE at this two wastewaters.
