Background The industrial sewage contains a large amount of suspended particles, colloid impurities and soluble pollutants, flocculation treatment is one of core processes in industrial sewage pretreatment and advanced treatment, and fine impurities and colloid particles in the water collide with each other and are coagulated to form flocculates with larger particle size by adding a flocculation reagent into the sewage, so that the separation of the pollutants and the water body is realized, and a foundation is laid for subsequent filtration, emission or reuse. At present, the existing industrial sewage flocculation treatment device generally adopts a step-by-step treatment mode of flocculation before separation, namely, the mixing and reaction of sewage and flocculation reagent are finished in a flocculation tank, and after the flocculation reaction is finished completely, mixed liquor containing a large amount of flocculates is conveyed to separation equipment to realize the separation of the flocculates and the clean water. However, in the actual operation process, as the separation of the flocculate is not carried out in the flocculation reaction process, the concentration of the flocculate in the flocculation tank is gradually increased along with the continuous proceeding of the flocculation reaction, on one hand, the viscosity of the water body is increased, the sewage and the unreacted flocculation reagent are prevented from being fully mixed and collided, the speed and the effect of the flocculation reaction are reduced, partial fine impurities cannot be effectively coagulated, the subsequent separation effect is influenced, on the other hand, the flocculate with the too high concentration is easy to collide and break, the fine flocculate is formed, the effective separation is difficult to realize, even secondary pollution is caused, and the subsequent treatment load is increased.
