摘　　要：在絮凝动力学、流体力学和絮凝体形态学的基础上,结合絮凝池内的水流特性、颗粒碰撞理论以及紊流能谱,系统阐述了G值、GT值、GT/Re(1/2)、E1/3t、E1/3tT、欧拉准数Eu、单位造涡强度Fs、分形维数指标和D/UL等絮凝过程水力学指标的控制原理与控制方法,总结了不同工艺合理选择絮凝过程控制方法的基本原则,提出了结合水力学相似准数、利用现代摄像技术与计算机手段进行适时监控的絮凝控制指标研究方向。Based on flocculation dynamics, hydrodynamics and flocs morphology, combined with the hydraulic characteristics, particle collision theory and turbulence spectrum in the flocculation tank, the control principles and control methods of several hydraulic indicators, such as G value, GT value, GT/√Re、Et^1/3、Et^1/3T, Euler number, the unit capacity of making vortex, fractal dimension index, D/ UL and so on were systematically expounded. The fundamental principles of choosing reasonable control methods of different flocculation processes were summarized. As an oriented research direction, timely monitoring on floeculation efficiency should be a cause for concern, which is established by using modern photographic techniques and advanced computer means, combined with hydrodynamic similarity criteri- on.
