| 摘 要： | 为了处理高浓度、高色度、高COD的印染废水，利用硫酸亚铁、工业废酸和金属下脚料自行配制了复合混凝剂，并将其与聚合双酸铝铁、聚合氯化铝铁、硫酸亚铁对印染废水的混凝效果进行对比。研究表明，复合混凝剂处理印染废水具有成本低、效果好的特点。当硫酸亚铁的投加量为200mg/L，复合混凝剂的投加量为1280mg／L，PAM的用量为2mg／L时，脱色率达94．9％，COD去除率达78．1％，悬浮固体（SS）去除率达90．9％。

| Abstract: | The mixture of ferrous sulfate, spent acid, from the metal residue in electroplating was used to prepare a coagulant agent for the treatment of dyeing wastewater with high content of color chrominance and COD. In comparison with PAFCS, PAFC, and ferrous sulfate, the effect of the new coagulant agent was satisfactory,and the cost was low. The best parameters were ferrous sulfate dosage of 200 mg/L,spent acid dosage of I 280 mg/L,PAM dosage of 2 mg/L. Under these conditions,the decolorizing rate was 94.9% ,the removal rate of COD was 78.1% and the removal rate of suspension solid was 90.9%. |
