Description
Technical field
The utility model relates to a kind of air floatation machines.
Background technique
Gas floatation process is a kind of efficient solid-liquid separating method, the suspended matter being mainly used in water removal.Its working principle is that
Raw sewerage is initially entered equipped with the small inflatable section for generating microbubble.Sewage passes through inflation during rising
Section, wadding body and suspended matter are sufficiently mixed with microbubble and contact, since there are density contrasts between gas-solid mixture and liquid, so that produce
A raw buoyancy vertically upward, takes solid suspension to the water surface.Air-dispersing bubble is attached on suspended matter in floating-upward process, is reached
Solid suspension just relies on the support of these bubbles to maintain the water surface after the water surface, forms scum layer, and scum layer passes through continuous moving
Chain Slag Scraping Device, which scrapes in sludge sump, to be removed.
Processing for the sewage being discharged in the food enterprises contains more oily substance and food in such sewage
Object disintegrating slag, common air floatation machine, which only passes through, drives the method risen to suspended matter using buoyant gas, broken for relatively large food
Slag is difficult to drive floating, and is easily attached to air floatation machine bottom wall in the case of grease condensation at low ambient temperatures and adheres to swill,
Air bearing slagging-off effect is set to decline to a great extent.
Summary of the invention
