Flocculation Effect Detection of Chemical Wastewater Based on Image Processing

With the image correction technology, a deep study and analysis was performed on the mutual relationships among a series of key parameters, including the coagulant dosage and the equivalent diameter, fractal dimension and concentration characteristics of the flocculation image, in the correction process of the chemical wastewater. Considering the actual operation environment and the real-time requirements of automatic dosing control, the Retinex algorithm was adopted in this article to solve the problems of uneven light distribution occurring in the process of experiment. In addition, another algorithm, the simple algorithm, was also applied to the calculation in the link of image correction, so as to shrink the program scale. According to the simulation results, it was indicated that the simulation operation was of relatively good practicability in the practical automatic control.
