一种PFS-Att复合絮凝剂的制备和应用

摘要

絮凝是一种常用的水处理方法，絮凝药剂的种类繁多.在实际应用中，常根据絮凝剂性质的不同将它们加以复合.采用自制聚合硫酸铁和活化处理后的凹凸棒土合成一种复合絮凝剂，用于处理造纸废水、印染废水和制药废水，具有良好的处理效果.复合絮凝剂的最佳投加量为0.4~0.5 g/L，适应废水pH为6~8.%Flocculation is one method commonly used for water treatment,and there are many types of flocculating agents. In practice,according to their,flocculants are often composited. We introduced a kind of composite flocculant which was synthesized by polymeric ferric sulfate and attapulgite,and it has good effect with the composite flocculant to treat papermaking wastewater,printing and dyeing wastewater and pharmaceutical wastewater. The optimal dosing quantity is 0.4~0.5 g/L,the pH value of waste water is 6~8.
