摘　　要：为了考察铁碳微电解法预处理提高印染废水的可生化性,先通过单因素实验探讨铁碳质量比、反应时间、反应pH值和曝气量等4个因素对废水COD降解效率及B/C比值提高的影响,再由单因素实验结果设计四因素三水平正交试验,确定最佳工艺参数。实验结果表明,铁碳比为1 1、反应时间2.5 h、pH值为3.25~3.50、曝气量为15.0 L/min为最佳工艺参数组合,出水B/C比值为0.5,各因素影响排序为铁碳比>反应时间=反应pH值>曝气量。To investigate the biodegradability of printing and dyeing wastewater by using iron - carbon micro - electrolysis method, the single factor tests are carried out to discuss the effects of Fe - C ratio, reaction time, pH value and aeration rate on COD degradation efficiency and B/C. Based on the single factor tests, the L9（34） orthogonal test is designed to determine the optimal factors. The experimental result show that, under the optimum factor combinations, 1 ： 1 of Fe/C ratio, 2.5 h of reaction time, 3.25 - 3.50 of pH value and 15.0 L/rain of aeration rate, B/C of effluent water is 0.5 and the influencing sequence of each factor follows： Fe/C ratio 〉 reaction time = pH value 〉 aeration rate.
