Abstract

Flocculation is the most widely adopted method in wastewater treatment, and it is influenced directly bythe characteristics of the flocculants.The application of the comuputer visual detection system to the wastewater flocculating treatment has been studied.First, the structure, design principles and method of the system are introduced in detail.Flocculation and precipitation test of two kinds of flocculants in simulated wastewater have been done.Image treatment technique of the computer is made use of to analyse the floc images, finding out the parameters relating to the floc precipitation characteristics and getting the curve of floc image gray scale value and the turbidity of the solution.The method that judges the end-point of flocculation process by using the gray scale square diagram of the floc images is put forward.Basis for the automatic control of flocculation process is provided.
