摘　　要：采用铁屑—活性炭内电解法作为光合细菌处理实际染料废水的预处理方法,考察了3个主要影响因素(铁炭比、停留时间、初始pH值)。结果表明,最佳的处理条件为:铁炭比为7∶3,pH值为5,停留时间为60 min。在上述最佳处理条件下,对初始CODCr为6 790 mg/L的染料废水处理效率可以达到66.1%,并且废水经预处理后可生化性得到大大提高,有利于后续生化处理的进行。　The treatment of dyestuff waste water by iron chips-activated carbon internal electrolysis is investigated,and the influence of three factors（the ratio of iron to carbon,reaction time,original pH value）on the results are discussed.The results show that the best conditions are as follows： the ratio of iron to carbon is 7∶3,pH value is 5,reaction time is 60 min.Under the best conditions,the removal ratio of CODCr is up to 66.1%.
