丙烯腈聚合废水的絮凝处理

Flocculation Treatment of Acrylic Polymeric Wastewater

采用絮凝方法,利用明矾、氯化铁和硫酸亚铁三种絮凝剂对丙烯腈聚合废水的处理进行了研究,找出最佳pH和絮凝剂用量。结果表明,明矾、氯化铁和硫酸亚铁的最佳pH分别为8.5、8.5和9,在各自的最佳pH条件下,三种絮凝剂的最佳用量分别为200mg/l、250mg/l和400mg/l。

This paper introduces the study on the flocculation treatment of acrylic polymeric wastewater by using alum,ferric chloride and ferrous sulphate as coagulants. The research result shows that the optimum pH values of alum,ferric chloride and ferrous sulphate are respectively 8.5, 8.5 and 9. At their optimal pH values,the optimial volums of these coagulants are 200mg/l,250mg/l and 400mg/l respectively.
