Abstract
The invention discloses a progressive air flotation device, which can effectively overcome the drawbacks of the traditional serial two-stage air flotation device. In the progressive air flotation device, waste water enters from an aerator, and oil, suspended substances and other wastes in the waste water subjected to coagulation and flocculation reactions in a front stage first rise up to the surface of the waste water under the supporting action of air bubbles generated by the aerator, then are constantly removed to a waste collection tank by a slag scraper and finally are conveyed out by a screw conveyor; and the waste water moves forward under the action of gravity and overflows from a lower part into a second stage to be further mixed by a back-flow device and an air dissolution device to remove oil and wastes which rise up to the surface. Thus, the wastes are removed and the aim of the invention is fulfilled.
