Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment, and in particular relates to a rapid mixing device for inducing adsorption fluidized bed. Background Art

[0002] Induced adsorption fluidized bed technology is widely used in the water treatment industry, involving processes such as hardness removal, dephosphorization, defluorination and heavy metal removal. In the existing induced adsorption fluidized bed technology, the liquid medicine is usually injected directly into the fluidized bed through the liquid inlet. Due to the limitations of the liquid medicine injection point, the liquid medicine often cannot be quickly and evenly mixed with the treatment medium and filler after entering the fluidized bed. This uneven mixing phenomenon causes the local liquid medicine concentration to be too high or too low, which in turn affects the removal efficiency of the target pollutants. When the local liquid medicine concentration is too high, it will not only cause a waste of liquid medicine, but may also cause secondary pollution; if the liquid medicine concentration is too low, the target pollutants cannot be effectively removed, resulting in substandard effluent water quality.
