| 摘 要： | 采用酵母菌生物膜-水解酸化-BAF生物组合工艺处理油田高浓度三元驱废水。实验结果表明:酵母菌生物膜具有降解污染物和调节水质的双重作用,可保障后续生物处理工艺的稳定运行。酵母菌生物膜、水解酸化及二级BAF的最佳HRT分别为18,12,36 h。工艺连续运行25 d,生物组合工艺对废水黏度、HPAM及COD去除率分别为80%、40%和69%。处理后出水ρ(石油类)<1 mg/L,ρ(SS)<5 mg/L,中位粒径<0.3μm,出水水质可达SY/T 5329—2012《碎屑岩油藏注水水质推荐指标及分析方法》回注标准。

| Abstract: | Combined process of yeast biofilm-hydrolysis acidification-biological aerated filter was applied to treat high concentration of ASP flooding wastewater from oilfield.The results showed that the yeast biofilm could degrade the pollutants and adjust the influent quality,which guarantee the stable operation of the subsequent biological treatment.The optimal hydraulic retention times (HRT) of the yeast biofilm tank,hydrolysis acidification tank and BAF were 18,12,36 h,respectively.With continuous running for 25 d,the removal efficiency of the combined process on viscosity,HPAM and COD reached 80％,40％ and 69％,respectively.The combined process could enable the concentration of crude oil less than 1 mg/L,the concentration of SS less than 5 mg/L and median particle size less than 0.3 μ,m.Effluent quality meets with the “Water Quality Standard and Practice for Analysis of Oilfield Injecting Water in Clastic Reservoirs” (SY/T 5329-2012). |
