| 摘 要： | 本文首先阐述由环形水槽试验所得出的细颗粒泥沙动水絮凝的若干规律。然后进行絮凝体形成和破碎的机理分析。从而得出产生动水絮凝的充分、必要条件:一是泥沙和电介质的物理、化学性质;二是絮凝体的抗剪能力大于所受到的剪切力,由此引出动水絮凝临界流速的概念。

| Abstract: | Some laws on hydrodynamic f locculation of fine sediments found in the circular channel test was elaborated at the beginning of the paper. Then, based on the mechanistic analysis on the forming and breaking of floes, the sufficiency and requirement of producing hydro-dynamic flocculation was given as follows: 1) physical and chemical properties of fine sediments and dielectrics; 2) greater shearing strength of hydrodynamic flocculation than the shear force it bears. It leads to the concept about critical velocity in hydrodynamic floccu-lation. |
