Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a dissolved air release amount detection device. Background Technique

[0002] In the shallow tank dissolved air flotation method, the sewage mixture is mixed with air in the form of micron-sized fine bubbles through a dissolved air pump and a dissolved air pipe, so that the suspended impurity particles in the mixture adhere to each other in the pipeline to form a solid-liquid-gas three-phase mixture. Its density is much smaller than that of water, forming a floating body relying on the buoyancy of water, and the suspended matter filled with tiny bubbles quickly floats on the liquid surface to complete solid-liquid separation.

[0003] At present, the solubility of air in the mixture is affected by multiple factors such as temperature, pressure, and medium. Generally speaking, an increase in temperature will cause the movement speed of air molecules to increase and the solubility to decrease; while a decrease in temperature will slow down the movement speed of air molecules and increase the solubility. Pressure is also an important factor affecting the solubility of air.
