Flocculation settling tanks are well known as one type of settling tank in drainage. Flocculation is the most basic and extremely important treatment process in industrial water and domestic sewage treatment, and by adding some medicaments (commonly called coagulants and coagulant aids) into water, particles which are difficult to precipitate in water can be mutually polymerized to form colloid, and then the colloid is combined with impurities in the water body to form larger floccules. The floccule has strong adsorption force, and can adsorb suspended matters, partial bacteria and soluble matters. The floccule is absorbed, and the volume is increased to sink. The application of the coagulating sedimentation process in water treatment has been hundreds of years, and compared with other physicochemical methods, the coagulating sedimentation process has the advantages of good effluent quality, stable and reliable process operation, economy, practicability, simple operation and the like.
