Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of reclaimed water treatment, especially to a dosing and water distribution device for a gas floatation tank. BACKGROUND

[0002] Reclaimed water refers to treated municipal sewage or domestic sewage, and its water quality is between tap water (upper water) and sewage (lower water) discharged into a pipeline. Reclaimed water is usually water treated by deep purification, including water treated by deepening treatment after secondary treatment in a sewage treatment plant and water treated by concentrating bathing water, vegetable washing water and the like of large buildings and residential communities. Reclaimed water treatment requires the use of a gas floatation tank to remove particulate impurities in water.

[0003] When treating reclaimed water, the gas floatation tank also needs to be combined with a dosing device to disinfect the reclaimed water by using a medicament. According to the patent with the publication number CN210505709U, a dosing device for a gas floatation tank is disclosed, which sprays the mixed liquid of acid liquid and flocculant in the dosing tank into the pool through the dosing pipe and the dosing hole, so that the mixed liquid is sprayed into the pool in a large range and the speed of diffusion of the mixed liquid into the pool is accelerated. However, the principle of the gas floatation tank is to use a large number of micro-bubbles to capture and adsorb fine particulate matter, so that the fine particulate matter floats to achieve the effect of solid-liquid separation. Therefore, when the above-mentioned dosing device adds medicament to the gas floatation tank, the medicament is difficult to flow downward and fully react with water due to the continuous upward floating of bubbles, and the water treatment efficiency needs to be further improved, so further improvement is needed.
