摘要
聚合氯化铝(PACl)是水处理中应用较广泛的絮凝剂.研究表明,PACl中各种铝聚合物的含量直接影响其絮凝效率.本文综述铝的水解聚合特性以及制备絮凝剂过程中的铝聚合物生成机制,着重介绍了Al13聚合物的结构特性、生成机制以及制备过程中各种因素的影响,为Al13絮凝剂的进一步研究奠定了基础.
Much attention has been paid to palyaluminum chloride （PAC1） in recent years because of its higher efficiency and relatively lower costs compared with the traditional coagulants. It has been demonstrated that the aluminum species of PACl are responsible for coagulation efficiency. In this paper, the chemical characteristics of aluminum aqueous solution and the formation mechanism of aluminum polymer species are summarized, and more attention is given to the structure of Al13 polymer, the formation mechanism of Al13 polymer and the influence factors for preparing of PACl with high content of Al13. This paper provides the foundation for Al13 flocculant and its application.
