摘　　要：采用生物接触氧化工艺对炼油废碱液进行生化处理。结果表明,当进水COD浓度2 000~3 000 mg/L、硫化物浓度30~150 mg/L、挥发酚浓度0~4.5 mg/L时,维持系统水力停留时间48 h,可实现出水COD浓度、硫化物浓度和挥发酚浓度分别为70~300 mg/L、0~5.6 mg/L和<1.0 mg/L,去除率分别为80%~97%,94%~100%和98%~99%。当生化系统受到污染负荷冲击时,COD和硫化物处理能力3 d后能恢复正常。The refinery alkali waste liquor was treated by the biologic contact oxidation process in this study. The results show that the effluent COD,sulfide and phenol concentrations could be reduced to 70 -300 mg / L,0 - 5. 6 mg / L and 1. 0 mg / L with the HRT as 48 h when the influent concentration of COD,sulfide and phenol concentrations were among 2 000 - 3 000 mg / L,30 - 150 mg / L and 0 -4. 5 mg / L,respectively. The removal rate of COD,sulfide and phenol were 80% - 97%,94% - 100%,and 98% - 99% respectively. The treatment capacity of the biochemical system could recover in 3 d when it was impacted by the high pollutant load.
