水处理絮凝动力学研究进展

Research Progress on Flocculation Kinetics for Water Treatment

综述了水处理絮凝动力学模型的研究进展,介绍了Smoluchowski模型及其改进模型、微涡旋理论模型和群体平衡模型,对各模型的适用条件和优缺点进行了详细对比分析,指出今后的研究中,需结合实际情况作出假设并综合考虑絮体的形态结构(数量、大小、分形维数等)以及涡旋形态大小等因素,才能得出全面真实反映絮凝过程的动力学模型。

This paper reviews the research progress on flocculation kinetics model for water treatment, and introduces the Smoluchowski model and its improved model, micro vortex theory model and population balance model, compares and analyzes the applicability conditions, advantages and disadvantages of each model, and proposes that in the future study, assumption should be made based on actual conditions and floc morphology(quantity, size, fractal dimension, etc.) as well as the vortex shape size, so as to obtain a dynamic model that can fully reflect the flocculation process.
