摘　　要：随着国家愈发重视水污染的治理和水资源的可持续利用,水的处理技术和方法引起了广泛关注。絮凝法是最经济、重要、方便的水的处理方法之一,开发新型、高效的絮凝剂是优化絮凝过程的核心技术,也是当前科研工作者面临的重大课题。本研究以N-乙烯基甲酰胺(NVF)和(3-二甲氨基丙基)丙烯酰胺(DMAPAA)为主要单体,AIBA为引发剂,探索了不同实验条件对共聚物性能的影响,合成了具有优异絮凝性能的共聚物。加入共聚物后的处理沉降物含水率(0.289)比不加的含水率(0.335)大大降低。In recent years,the state has paid more and more attention to the control of water pollution and the sustainable use of water resources.Therefore,the technology and method of water treatment have attracted wide attention.Flocculation is one of the most economical,important and convenient water treatment methods.Developing new and efficient flocculants is the core technology to optimize the flocculation process,and it is also the goal pursued by researchers in recent years.In this study,N-vinyl formamide(NVF)and(3-dimethylaminopropyl)acrylamide(DMAPAA)were used as the main monomers and AIBA as the initiator.The effects of different experimental conditions on the properties of copolymers were investigated,and copolymers with excellent flocculation properties were synthesized.The water content of the fallout with the addition of copolymer(0.289)is significantly lower than that without the addition of copolymer(0.335).
