Industrial wastewater is the most important reason of water pollution caused by industrial pollution, and it accounts for most of the pollutants discharged by industry, the pollutants contained in industrial wastewater are different due to different types of factories, even if the same type of factory, the quality and quantity of pollutants contained in the production process are not the same, in addition to the direct injection of wastewater discharged by industry into water body to cause pollution, solid waste and waste gas also pollute water body.

[0003] In the sewage treatment process, the suspended particles in water or liquid need to be aggregated and enlarged, or flocculation is formed, so as to accelerate the aggregation and sedimentation of particles, and the purpose of solid-liquid separation is achieved. This phenomenon or operation is called flocculation. Usually, the implementation of flocculation relies on the addition of appropriate flocculants, which can adsorb particles and "bridge" between particles, thereby promoting aggregation. In the latex industry, flocculation is the first stage of latex coagulation. The flocculant is usually an electrolyte such as ammonium salt or a colloidal chemical with adsorption function, but there are the following problems in the flocculation process: 1. In the treatment process, the flocculation liquid needs to be effectively mixed, but the common flocculation device is not sufficient for the mixing of sewage, resulting in unsatisfactory flocculation effect. 2. The pipe connection diameter of the liquid inlet connecting pipe of the common flocculation tank in the sewage flow process is fixed, which causes the problem of single connecting pipe caused by the limitation of connecting pipe specification.
