摘　　要：采用厌氧复合床/生物铁法串联工艺处理维生素B1生产废水,考察了水力停留时间(HRT)、反应温度、pH、溶解氧(DO)浓度等因素对处理效果的影响,确定了系统的最佳运行参数。结果表明,系统的最佳运行参数:厌氧复合床的HRT为12 h、反应温度为35℃、pH值为7.5,生物铁反应器中污泥含铁率为6%、HRT为12 h、DO浓度为3 mg/L;在最佳运行条件下,当进水COD和SO42-浓度分别为2 836、1 250 mg/L时,系统出水COD和SO42-浓度分别可降至171、137 mg/L,满足《污水排入城市下水道水质标准》(CJ 3082—1999)的要求。The combined anaerobic reactor/bio-ferric process was applied to treat the vitamin B1 production wastewater. The effects of HRT, temperature, pH and DO concentration on the treatment efficiency were investigated, and the optimal operation parameters of the system were determined. The results show that the optimal operation parameters of the system are as follows： in the combined anaerobic reactor, HRT is 12 h, reaction temperature is 35 ℃ and pH value is 7.5, and in the bio-ferric process, the ferric rate of sludge is 6%, HRT is 12 h, and DO concentration is 3 mg/L. Under the optimal operation conditions, when the concentrations of COD and SO4^2- in the influent are 2 836 mg/L and 1 250 mg/L respectively, the effluent COD and SO4^2- concentrations decrease to 171 mg/L and 137 mg/L respectively, meeting the Discharge Standard for Municipal Wastewater （CJ 3082 -1999）.
