摘要：
生物膜反应器近年来广泛应用于高浓度生活污水和工业废水的处理。采用日本新型Biofringe(BF)填料与A/O工艺相结合,并利用生物膜反应器的优点,处理石油化工废水。结果表明:水力停留时间为30h,回流比为2.5的条件下,石油化工废水中COD、NH3-N、TN的平均去除率分别为88%、99%、70%,出水水质达到国家污水综合排放一级标准。

Abstract:
Biofilm reactor is applied widely to treat highly concentrated domestic sewage and industrial wastewater.Integrated with the advantages of biofilm reactor,the Biofringe(BF)carrier has been used for treating petrochemical wastewater by using A/O process in the reactor.The results show that the process has a high removal efficiency:removal rate of CODCr,NH3-N,TN is 88%,99%,70% respectively,under the conditions of HRT 30 h,R 250%.The effluent quality is stable and conforms to the first-grade of the integrated wastewater discharge standard.
