摘要
传统混凝理论是在经典胶体化学的基础上，假定胶体颗粒为球形建立的。混凝形态学则着重研究胶粒和絮凝剂的形态特征及其对混凝效果的影响。本文在归纳混凝形态学基本理论的基础上，利用电子显微镜等现代分析仪器，研究了多种胶粒的形态特征，分析了这些形态特征对胶体稳定性、混凝效果、混凝动力学的影响，并对传统混凝理论忽略胶粒形态因素所造成的偏差进行了修正。
Abstract Classical theory of flocculation is based on the assumptions of globe shape of colloid particle. Flocculation morphology is to study the different morphoses (including shape, size, symmetry, space structure and special connection way) of different kinds of colloid particles and coagulants and their effects on flocculation. Based on the theory of flocculation morphology, the morphoses of different kinds of colloid particle are observed by electron microscope test and their effects on colloid stability, flocculation, coagulation kinetics etc are studied. It is confirmed that the classic theory have some deviations in coagulation of non spherical particle and these deviations are revised by flocculation morphology model.
