摘　　要：利用驯化筛选的苯胺优势降解菌人苍白杆菌(Ochrobactrumanthropi)在内循环三相流化床内处理含苯胺废水,以自行研制的纤维颗粒为载体,研究了溶解氧(DO)和水力停留时间(HRT)对苯胺降解过程的影响,探讨了反应器抗废水浓度负荷冲击的能力并考察了反应器对含苯胺生产废水的处理效果。结果显示,在4d内微生物开始附着纤维载体生长,反应器经过30d驯化启动即进入稳定状态;对废水获得良好的处理效果。由此证明了优势菌种与生物流化床结合处理毒性难降解苯胺废水的高效性。The treatment of aniline wastewater by internal loop three-phase fluidized bed coupled with Ochrobactrum anthropi which was isolated and domesticated from soil and water polluted by aniline was investigated with prepared fibre-granula as carrier.A variety of degradation conditions including dissolved oxygen(DO),hydro-retention time(HRT)and resistant capacity of concentration load shock were studied to provide information and recommendations for large-scale biological treatment of aniline-containing wastewater.The results showed that microorganism had settled on the surface of granula in 4 days and the reactor had achieved stable state for 30-day domestication.Moreover,it had successfully eliminated the wastewater containing aniline from a pharmaceutical factory.
