复合混凝剂PAFM混凝脱色性能研究

Study on Coagulation and Decolorization of PAFM

以黄铁矿烧渣和食盐电解含镁废渣为主要原料研制了一种复合脱色混凝剂ＰＡＦＭ。试验了它的混凝除浊性能和对染料废水的脱色效果，并对其混凝脱色机理进行了探讨。实验结果表明：ＰＡＦＭ具有良好的混凝除浊能力，用于多种料色废水处理，在ｐＨ值５０～１３０范围内。

A new kind of coagulant and decolourant PAFM has been prepared by using pyrite slag and waste residue containing magnesium as primary row materials.Test about its turidity removal and application in dye_containing wastewater was made.The coagulation and decolorization mechanism was discussed.The experimental results showed that PAFM gives the better capacity for turbidity removal.The decolourant has a good effect with wide scope of pH in dyeing wastewater treatment.
