摘　　要：在水处理过程中,随着相关研究的不断深入,混凝除藻的理论体系变得越来越丰富和完善。混凝除藻由传统混凝剂(主要是铁和铝)除藻,逐渐衍生出复合混凝剂除藻、新型混凝剂(如钛盐)除藻。研究发现,相较于单纯的混凝,预氧化混凝除藻拥有更好的去除效果。当前,很多学者综合运用混凝技术与其他技术来除藻,并对其处理效果和机理进行深入研究。混凝方法由开始的投加单一混凝剂除藻,慢慢地变为多种方式的联用协同除藻。新的混凝剂的研究和多种工艺的联合使用变得更为广泛,理论研究和实际应用都取得了很大的进步。In the process of water treatment, with the deepening of relevant research, the theoretical system of coagulation and algae removal has become more and more abundant and perfect. The coagulation algae removes algae from traditional coagulants (mainly iron and aluminum), and gradually decomposes the algae by the composite coagulant and the new coagulant (such as titanium salt). The study found that pre-oxidation coagulation algae removal has better removal effect than simple coagulation. At present, many scholars use coagulation technology and other techniques to remove algae, and conduct in-depth research on its treatment effect and mechanism. The coagulation method removes algae from the initial addition of a single coagulant, and slowly becomes a combination of various ways to synergistic algae removal. The research of new coagulants and the combined use of various processes have become more extensive, and great progress has been made in theoretical research and practical applications.
