Abstract:

Aiming at the necessity of wastewater purification, the relationship between the alum floc characteristics and the dosage of flocculant has been studied. The alum floc characteristics can be identified by using the digital image processing technique, through the operations, such as collecting the alum floc images, filtering, equalization, segmenting the imagines, etc., and the statistical date can be accomplished. The relationship between the dosage of flocculant and the diameter of alum floc particles can be obtained by experiments.

Key words: digital image processing, alum floc, flocculants

摘要：

针对污水净化需求,研究了矾花特征和絮凝剂加入量之间的联系,利用数字图像处理技术,经过对采集到的矾花图像进行滤波、均衡化、图像分割等操作,完成对矾花的特征识别统计,并通过实验得出絮凝剂加入量和矾花粒径之间的关系。
