【摘要】 本文从分析絮凝体密度和其构造形态的关系出发,提出了理想化结团絮凝体的构造模式。通过对实际结团凝聚装置中作用在结团絮凝体上的各种外力的分析可认为高体积浓度悬浮层中絮凝体之间的摩擦力和挤压力是促使构成絮凝体的初始粒子规则排列,形成高密度结团絮凝体的主要动力。各外力与结团絮凝体的内聚力达到平衡的条件决定了结团絮凝体的构造形态和它的密度。试验结果基本上证实了这些特点。更多还原

【Abstract】 An idealized model of pellet floc is presented in this paper by follwing an analysis of the relationship between floc density and the agglomeration manner of the primary particles which form the floc,By analysing the forces acting on pellet flocs in practical pellet coagulation unit,it is proposed that the robbing forces and pressing forces between flocs in suspended blanket of high volumetric concentration are main forces promoting regular agglomeration of the primary particles forming high density pellet floc.The type of structure and the density of pellet flocs are determined by the equilibrium condition of their inner bonding forces with the external forces exerting on it.Results of experiment have proved the above proposition.更多还原
