The vertical-flow multi stage flotation column for processing.
Background technology
In recent years, air supporting is widely used in sewage disposal, and especially the application in oil-polluted water field is more extensive.
Air supporting is that a kind of micro-bubble of utilization high degree of dispersion goes to stick the wadding grain in water for carrier, by the buoyance lift of bubble
Effect so as to which buoyancy, so as to realize the mandatory floating of grain of wadding a quilt with cotton, reaches a kind of detached skill of solid, liquid more than gravity and floating resistance
Art, can be divided into dispersion Bubble-floating Method, dissolved air flotation and electrolytic gas float glass process etc., at present in oil-containing, suspended matter-containing wastewater process often
For pressurized dissolved air flotation.
The principle of air-dissolving air-float is under an increased pressure, to make air soluble in water, forms air hypersaturated state, is then subtracted
To normal pressure, air is separated out, form a large amount of to close microbubble group, and make float and colloid micro- in slow uphill process
Grain, in bubble surface enrichment, and floats on the surface of the water with bubble, so as to reach the purpose for removing SS and CODcr, realizes air supporting.Pressurization
The main body of air-dissolving air-float can be divided into air-dissolving apparatus and gas floatation separation device, be usually used in having air supporting as gas floatation separation device at present
