摘　　要：采用不同培养基与菌群驯化方式,从焦化厂好氧污泥中筛选出一个苯酚降解菌群BF,进行了细菌群落结构分析、菌群降解特性分析与规模化验证实验。结果表明,在24~34℃、pH中性条件下,经40 d驯化后,菌群BF将焦化废水COD降至195 mg/L,较焦化厂出水平均COD降低了302 mg/L,降解率超过60.8%。经臭氧深度处理后,进一步将焦化废水COD降至148 mg/L,达到国家间接排放标准要求。Using different kinds of media and microbiota acclimatization approaches, a phenol degradation microbi- ota, BF, has been screened out from aerobic sludge of a coking plant. Bacterial community composition analysis, degradation characteristic analysis and ton-scale verifying experiments are carried out. Results indicate that after a 40-day acclimatization, BF can make the COD of coking wastewater decrease to 195 mg/L under 24-34℃ and neutral pH conditions, 302 mg/L lower than that of the average effluent COD of the coking plant, and its degrada- tion rate is more than 60.8%. After treated by ozonation advanced treatment, the COD of coking wastewater can be further decreased to 148 mg/L, meeting the requirements for the national indirect discharge standard.
