本文主要是作者以前的研究，这是旨在建立一个理论协议的絮凝器的设计和操作的基础上，从实验和模拟的絮凝过程的数据进行回顾。絮凝是快速砂滤系统的主要预处理过程，该过程在沉淀池中产生可沉降的絮体，减少流向砂滤机的固体负荷。我们试图通过结合絮凝研究的三个类别：絮凝体特性，絮凝动力学和絮凝工程方面，在絮凝器的设计和操作中从经验方法过渡到理论方法。提出了絮体密度函数和絮体强度函数作为絮体的重要属性。Levich方程基于粘性分区扩散控制的假设，代表了絮凝过程中的基本碰撞动力学。最后，介绍了絮凝研究的工程应用实例。
This paper is mainly a review of the author's previous research, which was aimed at establishing a theoretical protocol for the design and operation of flocculators based on data from experiments and simulations of the flocculation process. Flocculation is the main pretreatment process of the rapid sand filtration system, and the process produces settleable flocs in the sedimentation basin, reducing the solid load flowing to the sand filter. We tried to make the transition from empirical to theoretical approaches in the design and operation of flocculators by combining the three categories of flocculation research: floc characteristics, flocculation kinetics, and engineering aspects of flocculation. The floc density function and the floc strength function were proposed as important attributes of floc. The Levich's Equation, based on the assumption of viscous subrange diffusion control, represented the basic collision kinetics during flocculation. Finally, examples of engineering applications using our flocculation research were described.
