摘　　要：聚合氯化铝(PAC)具有阳电荷密度高、分子结构大的特点,其制备和应用技术成熟。该文简介了PAC的制备工艺,综述了PAC在造纸工业废水处理、化机浆和白水阴离子垃圾中和与捕集、中/碱性施胶剂施胶效果的改善和水解产物的控制和复合型新型表面施胶剂的开发等方面的应用,并列举实例阐述了其应用效果。Polyaluminium chloride has the characteristics of high positive charge density and large molecular structure. Its preparation and application technologies are mature. This paper introduced preparation process of PAC briefly, and reviewed its application in wastewater treatment in papermaking industry, neutralization and capture of anionic trash in ehemimechanical pulp and white water, sizing effect improvement of neutral/alkaline sizing agent and control of its hydrolysate, and development of new composite surface sizing agent. And case studies were presented to elucidate its application efficiency.
