摘　　要：文章综述了水处理中絮凝动力学方面的研究进展。在分析絮凝机理基础上,分别回顾了异向絮凝动力学、差速沉降絮凝动力学和同向絮凝动力学的研究历程,从絮凝机理的认识过程到模拟模型的发展,详细介绍了模型的应用情况,并揭示了尚未解决的关键问题。The paper reviewed the progress of flocculation dynamics applications in the field of water treatment. On the analysis of floeeulation mechanism, perikinetie floeeulation, orthokinetie floeeulation and differential sedimentation were respectively described in terms of theory development and modeling progress. Many of unresolved critical issues were discussed when the models were applied in practice.
