摘　　要： 针对炼油高浓度污水硫、酚含量高及生化性差的特点,开发了由生物脱硫、Fe-C微电解、生物除酚、吸附-生物降解法(AB法)和内循环曝气生物滤池(BAF)等单元组合的处理技术.研究结果表明,控制生物脱硫、生物除酚、AB法和内循环BAF等生化反应器的溶解氧分别为2.0,2.0～2.4及AB法的A段为0.6～1.0,B段为1.5～2.0和大于2.4mg/L,水力停留时间分别为8～12,8～12,5～6和2.5～3.0h,Fe-C微电解的Fe/C质量比为3～4,pH值3.0～3.8,反应时间30min,则该污水的硫化物、挥发酚、COD、氨氮和石油类的平均浓度分别由705,225,4333,38.6和30.0mg/L降至0.3,0.07,80.5,11.6和2.9mg/L,达到排放标准. Aiming at the characteristics of high content of sulfur and phenolic pollutants and poor biochemical properties of high-concentration wastewater from oil refinery,a combined technology of biological desulfurization,Fe-C micro-electrolysis,biological phenol removal,adsorption-biodegradation process（AB method） and internal recycle biological aerated filter（BAF） was developed.The results showed that dissolved oxygen of the bio-reactors of biological desulfurization,biological removal of phenol,AB method and internal recycle BAF were controlled at 2.0 mg/L,2.0～2.4 mg/L,0.6～1.0 mg/L in section A,1.5～2.0 mg/L and ≥2.4 mg/L in section B by AB method respectively,hydraulic retention time（HRT） in 8～12,8～12,5～6 and 2.5～3.0 h respectively,Fe/C mass ratio of the Fe-C micro-electrolysis at 3～4,pH value in 3.0～3.8,and reaction time for 30 min,the average mass concentrations of sulfide,volatile phenol,COD,ammonia nitrogen and oil in the wastewater were reduced from 705,225,4333,38.6 and 30.0 mg/L to 0.3,0.07,80.5,11.6 and 2.9 mg/L respectively,thus meeting the national discharge standards.
