Abstract
The utility model relates to an air flotation device. The air flotation device is characterized by comprising a box body and an air dissolved water draining system, wherein the box body is sequentially divided into a pre-treatment area, an air flotation water collecting area and a clean water area; the air flotation water collecting area is divided into an air flotation area and a water collecting area through a flashing sheet; the air dissolved water draining system comprises a first air dissolved water draining pipeline positioned at the bottom part of the air flotation area, and a second air dissolved water draining pipeline positioned in the water collecting area. The air flotation device has the advantages that air dissolved water drained by the first air dissolved water draining pipeline in the air flotation area absorbs small granules in sewage, the small granules float on the liquid as bubble raises, a slag scrapping machine scraps suspended matters into a slag collecting tank, and then the water subjected to air flotation enters the water collecting area for secondary air flotation and then flows into the clean water area through a communication pipe consisting of a water collecting pipe and a water outlet pipe so as to be drained; the water is subjected to secondary air flotation in the water collecting area, and the bubble produced in the secondary air flotation is less than that produced in the first air flotation; any energy consumption is not increased basically while improving the treatment effect, and the normal water collection is also not influenced.
