摘要
分别运用无机絮凝剂Al2(SO4)3和FeCl3,对染料废水进行了前处理试验。为了提高无机絮凝剂的絮凝沉淀和脱色作用,在实验过程中还加入了脱色剂和阴离子聚合物聚丙烯酰胺。无机絮凝剂及其助剂对染料废水具有较好的絮凝沉淀作用,可以作为染料废水的前处理过程。
Separately using the inorganic congulants FeCl3 and Al2 （ SO4 ）3 in this test and the pretreatment to the dyeing wastewater was carried out. For the efficient removal of the foulants from the wastewater, the color removal agent and the anionic polymer were used together. Inorganic congulants and congulang aid had better coagulation and sedimentation function to the dyeing wastewater. The coagulation and sedimentation process was used as a pretreatment process to remove colors and organics from the dying wastewater in this study.
