基于数字图像处理技术的污水自动加絮凝剂研究

Research on the automatic flocculant adding in wastewater treatment based on digital image processing technique

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。

Aiming at the necessity of wastewater purification, the relationship between the alum floe characteristics and the dosage of floeeulant has been studied. The alum floe eharaeteristies can be identified by using the digital image processing technique, through the operations, such as collecting the alum floe images, filtering, equalization, segmenting the imagines,ete., and the statistieal date ean be aeeomplished. The relationship between the dosage of floeculant and the diameter of alum floe particles can be obtained by experiments.
