为了探究絮凝剂强化微电解法对印染废水的处理效果，以罗丹明B模拟废水为处理对象进行试验研究。通过间歇式和连续式的处理方式进行试验，分析停留时间、废水初始pH值、填料配比、絮凝剂投加量等单因子对降解罗丹明B废水的影响，并通过正交试验研究各因素对该法处理罗丹明B模拟废水的效应。结果表明，絮凝剂与微电解法结合在处理罗丹明B模拟废水时具有明显的协同作用；溶液初始pH值=3，铁炭比（Fe∶C）=1∶1，混凝剂投加量=10mL，初始浓度=100mg·L-1等条件下处理效果较好，连续式处理停留时间为70min。通过正交试验分析得出，5个因素对系统色度去除率影响主次顺序为：模拟废水初始浓度＞停留时间＞混凝剂投加量＞模拟废水pH值＞填料配比；5个因素影响COD去除率的主次关系为：模拟废水初始浓度>模拟废水pH值＞填料配比＞混凝剂投加量＞停留时间。

To explore the effects of the iron-carbon micro-electrolysis and coagulation methods in treating printing and dyeing wastewater, experimental study was carried out by dealing with Rhodamine B simulated wastewater. The effect of single factor residence time, initial pH value, stuffing material ratio and dosage of coagulant on degrading Rhodamine B wastewater was investigated by running the experiment in both intermittent and continuous modes. Orthogonal tests were further performed to ifnd out the contribution of these factors to the speciifc method in use. The results showed that the micro-electrolysis method acted in obvious synergy with the coagulation method and that satisfying performances were achieved when initial pH was 3, stufifng material ratio was 1∶1 (Fe∶ C), dosage of coagulant was 10mL, initial concentration of the dye was 100mg/L in intermittent mode and residence time was 70min in continuous mode, respectively. According to the results of orthogonal tests, the ifve factors could be sorted by their influence on therate of color removal as followed: the initial concentration of wastewater> residence time> dosage of coagulant>pH of simulated wastewater>stufifng material ratio, and by their impact on the rate of COD removal: the initial concentration of wastewater>pH of simulated wastewater>stufifng material ratio>dosage of coagulant> residence time.
