摘要
聚丙烯酰胺(PAM)型絮凝剂具有良好的絮凝性,可以广泛地应用在水处理和造纸等工业工程中。本文探讨了聚丙烯酰胺(PAM)型絮凝剂的作用机理,其机理作用类型可以分为吸附架桥作用、吸附-典型中和作用、网铺-卷扫作用。从作用机理出发可以探讨其分子设计的基本条件,并分析了应用PAM絮凝剂对于环境的积极和消极的影响。
Polyacrylamide(PAM)flocculant has good flocculability and can be widely used in water treatment and papermaking and other industrial projects.The mechanism of action of polyacrylamide(PAM)flocculant is discussed in this paper.The mechanism can be divided into adsorption bridging,adsorption-typical neutralization and meshing-sweeping.The basic conditions of molecular design can be discussed from the mechanism of action,and the positive and negative effects of PAM flocculant on environment are analyzed.
