摘　　要：本文是多年研究的总结。1985年以确定高浊度水处理絮凝剂投量为契机,肯定了泥沙颗粒因素以比表面积为特征参数对投药量起着重要的作用,提出了关系式。通过生产试验又提出了闭环自控投药系统的考虑了颗粒因素的基本数学模式。在一系列试验研究中还确定了泥沙比表面积对自然沉速、沉泥浓度、原水浊度的影响,从而较系统地明确了泥沙颗粒因素在高浊度水研究中的重要作用。This article is the summarization of many years study. From the study of flocculantdosage for high-turbid water treatment in the 1985, authors have confirmed the impor-tant role of sediment particle factor, indicated by specific surface area of sediment parti-cles, and have obtained the relation between the flocculant dosage, the concentration andthe specific surface area of sediment particles. Through the plant test the basicmathematical model, basised on total surface area, for automatical close-cycle dosingcontrol system is developed. And through determined the series of experiments, the spe-cific surface area of sediment particles have an effect on plain settling velocity, on theconcentration of the sludge in settling tank and on the turbidity of raw water from theYellow River are found. Thereby, the important role of sediment particle factor inhigh-turbid water study is defined in a systematic way.
