摘要
文章采用铁屑一活性炭内电解法作为光合细菌生化处理染料废水的预处理方法,考查了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颐3,pH值为5,停留时间为60min。在上述最佳处理条件下,对初始COD为6790mg/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 wastewater is investigated with iron chips-activated carbon internal electrolysis. The influence of three factors （iron/carbon ratio, reaction time, pH） on the treatment efficiency is discussed. The best conditions obtained for water treatment are iron/carbon ratio of 7：3, pH 5, reaction time of 60 min. Under these conditions, the removal ratio of COD is 66. 1 %.
