Description
Technical field
The present invention relates to technical field of sewage, particularly relate to a kind of airfloat equipment.
Background technology
Airfloat equipment is that a class passes into or produces a large amount of micro bubbles in water, air is made to be attached on suspended particle with the micro-bubble form of high dispersing, cause density to be less than the state of water, utilize law of buoyancy to make it keep afloat, thus realize the water treating equipment of solid-liquid separation.Air supporting mode can be divided into loose gas air supporting, air-dissolving air-float (comprising vacuum By Bubble-floating Method) and electrolytic gas float glass process.Application is had at present in feedwater, trade effluent and municipal sewage treatment.The features such as airfloat equipment has less investment compared with other solid-liquid separation equipment, occupation of land face is minimum, level of automation is high, convenient operation and management.
Water treatment field air floatation machine be applied to following in:
1, fine suspension in surface water is separated, micro-aggressiveness such as algae.
2, useful matter in trade effluent is reclaimed, as paper pulp in paper waste etc.
3, mud in second pond isolation and identification water is replaced.
Airfloat equipment is all finally realize solid-liquid separation with the form of scum silica frost, reaches the object of water purification.The mode of airfloat equipment removing dross is mainly divided into two classes: one is adopt slag scraper to scrape slag; Two is adopt overflow and slag, and these two kinds of modes are all that scum silica frost is drained into slag bath, then by the deslagging pump of slag bath, scum silica frost are drained into sewage network.
According to a large amount of equipment service experience, scum silica frost still floats on above water body with the form of scum silica frost after entering slag bath, dissolves in bottom water body on a small quantity.The sewage of bottom can only be drained into sewage network by simple deslagging pump, the scum silica frost on top contains flocculation agent due to it, structure is sticky, water ratio is low, is difficult to dissolve in water, so cannot be discharged, so just cause the scum silica frost of slag bath cumulative, and then fermentation produces toxic and harmful, affects the health of machine room, threaten the personnel entering machine room.
