铝系混凝剂优势形态分析及其混凝特性

聚合氯化铝（PACl）是常用的水处理混凝剂，在应用过程中通常表现出比传统铝盐更为优异的效果.研究表明，这种优异性能主要得益于其特殊的组成，特别是高分子聚合物Al₁₃和Al₃₀独特的物化特性.Al₁₃和Al₃₀是铝离子水解过程中的中间产物，在地球科学和环境化学等领域有着重要的研究价值.于水处理而言，二者的结构和分子特性是研究者关注的重点，大量研究基于此展开，很多重要的发现为实际应用奠定了基础.基于对PACl及其组成性质的研究，本文对PACl的混凝特性及其优势形态分子的分析进行了综合阐述.

The analysis of dominant species in aluminous coagulants and their coagulation properties

Polyaluminum chloride (PACl) is a common water treatment coagulant, which usually exhibits better effects than traditional aluminum salts in the practical application process. Lots of investigations have shown that the excellent performance is mainly due to the special composition, especially the unique physical and chemical properties of polymer Al₁₃ and Al₃₀. Al₁₃ and Al₃₀ are intermediate products during the hydrolysis process of aluminum ions, which possess important research value in the fields of earth science and environmental chemistry. With regard to water treatment, the structure and molecular characteristics of the two polymers are the studied focus to the researchers. A large number of investigations have been carried out and many important results have been discovered and provided important instructions for practical applications. Based on the studies of PACl and its properties, the coagulation characteristics of PACl and the analysis of its dominant species were comprehensively reviewed in this article.
