Description

technical field

[0001] The invention belongs to the technical field of water treatment, and relates to a method and a system for synchronously detecting the fractal characteristics of flocs in water in different spatial dimensions on-line. Background technique

[0002] Today, coagulation is still an irreplaceable treatment unit in the water treatment process, and its effect directly affects the subsequent solid-liquid separation effect and the final effluent water quality. In recent years, with the development of the application of molecular biology in the field of water treatment technology, the agents used are not limited to chemical flocculants, biological flocculants have also been widely used and achieved better results in the treatment of special water quality. However, no matter what kind of agent is used, a good flocculation effect is always the goal pursued by related engineering technologies and researchers.

[0003] At present, the techniques used to indicate the...
