The air flotation system is mainly used for purification treatment of industrial sewage in papermaking, chemical industry, printing and dyeing, food, beer, pharmaceutical, slaughtering and other industries. The untreated sewage must first enter the aeration zone and fully mix with the micro-bubbles. The micro-bubbles will bring the suspended solids to the water surface in the process of rising, and the scraper will run along the liquid surface to scrape the suspended solids onto the inclined metal plate. , and then push it into the sludge discharge pipe groove, and flow into the sludge collector through the sludge discharge pipe groove. The power of the sludge scraper is only 0.5kw. After purification, the sewage will pass through the overflow tank under the inclined plate before discharge. The overflow tank is used to control the water level of the air flotation tank to ensure that the liquid in the tank will not flow into the sludge discharge pipe. The open pharynx flow pipe will flow from the aeration section Stretches along the bottom of the air flotation tank. While generating micro-bubbles, the vortex concave aerator will form a negative pressure zone at the bottom of the pool with a return pipe. This negative pressure will make the wastewater flow back from the bottom of the pool to the aeration zone, and then return to the air flotation section.
