摘　　要：絮凝体粒径分布可作为评价絮凝效果好坏的指标,也可以作为控制混凝剂投加的依据。采用数字图像处理技术,通过对采集的絮凝体图像进行预处理,结合图像Otsu二维分割、连通域判断等操作,实现了在线测量絮凝体粒径分布。结果表明,该方法可以快速准确地获取絮凝体的粒径分布,为控制混凝投药起到了很好的预警作用。Flocs diameter distribution could be used as indicators for evaluation of flocculation, also could be used as a basis for controlling the amount of coagulant dosage. A method for online measuring flocs diameter distribution was achieved which based on the digital image processing, pretreatment of collecting flocs image, two-dimensional cutting of Otsu and connected region judgment. The results indicated that this method could obtain flocs diameter distribution rapidly and accurately which plays an important warning role in controlling coagulant dosage.
