Description
Technical Field
The invention belongs to the technical field of sewage treatment, and particularly relates to a turbulent diffusion tank based on an air floatation coagulation system.
Background
The coagulation system is an extremely important link in the operation process of air floatation, and sewage enters the first process of air floatation, namely coagulation reaction; the coagulation process is a complex physicochemical process of the interaction between the coagulant and water and colloids and fine suspensions. Under the actions of dissociation of coagulant and hydrolysis products, colloidal pollutants and fine suspended matters in water are destabilized and aggregated into flocculating bodies with separability; the coagulation system comprises two stages, namely a mixing stage and a flocculation stage. The mixing stage forms smaller particles which are flocculated to form larger flocks. During the formation of the flock, not only the suspended particles but also a portion of the bacteria and dissolved substances are adsorbed.
In the coagulation process, sewage is discharged into a diffusion tank, a coagulant is added into the diffusion tank, and meanwhile, liquid in the diffusion tank is stirred by a stirrer, so that the liquid is rapidly circulated in the tank, and the liquid in a high-shear area and the liquid in a low-shear area are rapidly exchanged, so that the liquid in the diffusion tank is rapidly and uniformly mixed; the coagulant destabilizes and aggregates colloidal pollutants and fine suspended matters in water into floccules with separability, and separates the floccules from the water, thereby achieving the effect of purifying water.
In the process of coagulating sewage in the diffusion tank, the flocculants can be attached to the inner wall of the diffusion tank, after a long time, a thick layer of dirt can be attached to the inner wall of the diffusion tank, so that the volume of the diffusion tank is reduced, the coagulating effect is affected, the dirt is easy to cause blockage of a pipeline, and the flow of water flow is blocked.
To this end, the invention provides a turbulent diffusion cell based on an air-floating coagulation system.
