Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment, and in particular relates to an air-floating ion aeration system containing a degradation agent. Background Art

[0002] Ion flotation is a common water treatment technology. Its principle is to separate air or oxygen from dissolved gases in water to generate bubbles, so that pollutants suspended in water (such as suspended solids, grease, colloids, etc.) settle to the bottom of the water or float to the surface of the water, so as to purify water quality and improve water transparency. The existing flotation ion aeration system includes a flotation tank, which is provided with a coagulation zone, a flocculation zone, a mixing zone and a scraping zone, and a stirring assembly is installed on the top of the coagulation zone and the flocculation zone. The flotation ion aeration system also includes a dissolving tank, and the dissolving tank uses a releaser to transport bubbles into the water. When the flotation ion aeration system is transported to the coagulant and flocculant, the coagulant is more aggregated when entering the coagulation zone through the feed pipe, and the stirring assembly needs to stir for a long time to mix the coagulation zone with water.
