摘　　要：针对固定床气化废水总酚浓度高、毒性强、可生化性差等特点,采用折流式厌氧反应器(ABR)进行强化处理,分析了ABR反应器启动过程和总酚、COD、B/C处理效果。结果表明,在稀释原水并添加20 mg/L邻苯二酚作为共代谢基质下,ABR反应器在32 d内完成快速启动。稳定运行期,在进水COD 1458~1773 mg/L、进水总酚396~473 mg/L,进水pH 7.71~8.16、水温30±1℃的条件下,ABR出水COD、总酚浓度分别为793~1004 mg/L、227~271 mg/L,COD、总酚的平均去除率分别为45.0%、42.3%,废水可生化性由0.131提高至0.403。According to the high concentration,strong toxicity and poor biodegradability of total phenols in the gasification wastewater of Lurgi Gasifier,a baffled anaerobic reactor(ABR)was used to treat the gasification wastewater of Lurgi Gasifier.The start-up process of ABR were studied,as well as the treatment effect of total phenols,COD and B/C.The results showed that ABR reactor started up quickly in 32 days in a co-metabolism matrix which combining diluting raw water with 20 mg/L catechol.During the stable operation period,the effluent concentrations of COD and total phenol were 793~1004 mg/L and 227~271 mg/L,respectively,the average removal rates of COD and total phenol were 45.0%and 42.3%,the biodegradability of wastewater was increased from 0.131 to 0.403,under the conditions of influent concentration of COD and total phenol 1458~1773 mg/L,396~473 mg/L,water temperature of 30±1℃and pH of 7.71~8.16.
