摘　　要：流态化复合载体生物膜(FCBR)工艺使用中国石化石油化工科学研究院专利复合载体,可使生化反应器中的微生物浓度较常规流态化生物膜工艺增加近1倍,有效提高了生化处理能力和抗水质冲击能力,适用于处理高含盐炼油污水。某炼油厂的现场连续试验结果表明,在水力停留时间仅为厂内现有生化处理单元50%的情况下(20h),当进水COD质量浓度为185~620mg?L、氨氮质量浓度为18~60mg?L时,FCBR出水的COD质量浓度可降至150mg?L以下,氨氮质量浓度不超过11mg?L,悬浮物质量浓度基本不超过80mg?L,处理效果明显优于现有生化单元,同时具有较强的抗水质冲击能力,可稳定满足后续催化氧化单元的要求,具有工业化应用前景。Fluidized carrier biofilm process（FCBR）loading with RIPP patented carriers was utilized to treat refinery saline wastewater. The results prove that FCBR could effectively remove influent chemical oxygen demand（COD）, NH3-N and suspended solid from 185-620 mg/L, 18--60 mg/L and 50- 520 mg/L to no more than 150 mg/L, 11 mg/L and 80 mg/L, respectively within a hydraulic retention time of 20 h. Comparing with the existing biological treatment system in oil refinery,the new FCBR has a higher efficiency within only a half of a hydraulic retention time. Under the actions of fluidized carrier, biomass concentration doubles that of conventional biofilm processes,and the FCBR effluent quality re- mains stable and meets the water quality requirement of the subsequent catalytic oxidation processes. Furthermore,the operation of FCBR is easy and low-cost,therefore it has a great potential for commer- cial application.
