For example: algae in lakes, reservoirs and parts of rivers; plant residues and fine colloidal impurities; dye granules in the printing and dyeing industry; short fibers in the paper and chemical fiber industries; microdroplets of petroleum and organic solvents in the oil refining and chemical industries; heavy metal ions in the electroplating and pickling wastewater; electrophoretic paint waste water, and the like; are light particles having a specific gravity very close to that of water. For these raw water, if the conventional precipitation method is continued, the effect is inevitably poor, and particularly in the low temperature condition in winter, the treatment effect is more difficult to be ensured because the coagulation and hydraulic conditions are deteriorated. Conceivably, the flocs which are difficult to precipitate are hard to sink, but the work is half done, and rather than being directed at the reason, the air bubbles are artificially introduced into the water body to be adhered to the flocs, so that the overall density of the flocs is greatly reduced, and the flocs are forced to float upwards by virtue of the rising speed of the air bubbles, thereby realizing rapid solid-liquid separation. In this sense, the emergence of the air flotation technology is a revolution to the gravity settling method, and it opens up a new field of solid-liquid separation technology. The air floating machine is characterized in that a dissolved air system generates a large amount of micro bubbles in water, air is attached to suspended particles in a highly dispersed micro bubble mode, the density is lower than the water state, the air floating machine floats on the water surface by utilizing the buoyancy principle, and therefore solid-liquid separation water treatment equipment is realized.
