摘　　要：本文介绍了利用美达棉纤维挂载生物膜法处理石化废水中油的试验结果。当废水在柱内停留时间为６．３ｈ，废水中油的处理效果是令人满意的。在同一停留时间下入流水的ＣＯＤｃｒ从４２０ｍｇ／Ｌ变到１８３２ｍｇ／Ｌ时，出流水的ＣＯＤｃｒ在１６８．This paper presents the experimental results of the treatment of oil in petrochemical production wastewater by using biofilm hung in Meida fibre mainly composed of polypropylene. The removal efficiency of oil in wastewater was satisfactory when the retention time of wastewater in the columns was kept in 6.3 hours. At same retention time the COD Cr were below 168.5 mg/L in the effluent while the influent COD Cr changed from 420 mg/L to 1832 mg/L.
