摘　　要：在Fe3+存在下,考察了好氧活性污泥系统在p H值为5.0和9.5冲击7天下对制浆中段废水的处理效果和污泥特性,然后再调整p H值为7.0,进行7天的恢复实验,继续考察处理效果和污泥特性,并与不加铁的空白组对照。在p H值为5.0和9.5冲击下,加入铁离子组和空白组处理效果均下降,污泥沉降性能变差,但加铁组的各项指标均优于空白组。恢复实验中,加铁组的好氧活性污泥系统恢复到正常运行的速度相对较快。p H值为5.0冲击下,活性污泥系统处理效果优于p H值为9.5的冲击,但污泥沉降性能较差。In the presence of Fe3 ＋ , treatment efficiency of pulping middle stage effluent by aerobic activated sludge and sludge characteristics were studied when the sludge were shocked at pH = 5.0 and 9. 5 for 7 days. Then the recovery experiments were carried out for 7 days as the pH value was adjusted to 7.0. At the shocks at pH = 5.0 and 9. 5, the treatment efficiency decreased, the sludge settling performance deteriorated for both group with iron and blank group, but all the indicators of the group containing iron were better than that of the blank group. In the recovery experiments, sludge with iron recovered relatively rapidly. At the shock of pH = 5.0, the activated sludge treatment effect was better than that of pH = 9. 5, but the sludge settling performance was poor.
