摘要
颗粒物微界面的物理化学过程在混凝工艺中起着十分重要的决定作用.有关界面过程化学的研究构成了混凝技术研究与发展的重要内容和理论基础.本文仅以颗粒物/AOM-IPF水-溶液的相互作用为例,从水体颗粒物的稳定性、高效纳米絮凝剂的研究、微界面形态与过程以及混凝作用机理等诸方面,对该领域的研究与进展加以系统介绍.
The interfacial process chemistry of the aquatic particle, which forms the important content and theoretical basis for the research and development of coagulation technique, exhibits significant role during coagulation process. The inorganic polymer flocculant （IPF）-particle/AOM - aqueous solution interaction was discussed as an example in this paper, to illustrate the rapid advance in this area. The various aspects such as stability of the aquatic particulates, efficient nano-flocculant, micro-interface speciation and process, and the coagulation mechanism are discussed in detail.
