Description

A kind of modified model air floatation machine
Technical field
This utility model relates to sewage treatment area, particularly relates to a kind of modified model air floatation machine.
Background technology
Petroleum refining process can produce substantial amounts of oil-containing, saline sewage, this sewage have pollutant levels height, oil-containing, The features such as salinity is high, variation water quality is big, toxicity is big, at present for this kind of sewage, the most first use oil removal, air supporting method for floating Carry out pretreatment, after then concentrating, carry out biochemical treatment.
Wherein, pretreatment mainly removes the oil slick in sewage and emulsifying by methods such as precipitation, air supporting, coarse agglomeration Oil, biochemical treatment is mainly made a return journey the Organic substance in scrubbing water by the degraded of microorganism.
Air supporting preconditioning technique, substantially a gas-solid adsorption and the combined process of solid-liquid separation.In this mistake Cheng Zhong, small bubble adsorbs mutually with the granule of float in sewage, forms the solid three-phase mixed system of aqueous vapor, particle adhesion After upper bubble, device density produces Float upward function less than water, so that the pollutant in suspension are separated from the water out, is formed Scum silica frost, scum silica frost is removed by Slag Scraping Device.
In water technology, affect the factor of the scum silica frost moisture content that sewage air-flotation oil removing, effluent quality and air supporting produce More, wherein the size of bubble, particle diameter distribution, adhesion property are to weigh the key of air-float technology treatment effect.Because air supporting work Skill needs the microbubble of a large amount of high degree of dispersion to be less than as the particle overall proportion of adhesion formation in carrier, with pending water The flco of water, thus rely on buoyancy to rise to the water surface.
Macroscopic view bubble is in 1 meter of deep water, and the time of staying is less than 2 seconds, therefore short for time of contact with float, occurs to adhere to general Rate is low, and crude removal efficiency is low;Micro-nano gas time of staying of ducking in drink is long, and surface area increases, and extends time of contact with float, Dirt-removing power improves.Therefore, reduce bubble diameter, increase bubbles volume simultaneously and can improve bubble and contact with particle, adhere to Chance, is conducive to improving air flotation effect.
For the sewage oil removing of petrochemical industry, current commonly used traditional cavitation air flotation, heterogeneous air-dissolving air-float process.By In air flotation turbo produce bubble diameter mostly at 50 m~400 m, some is even up to 1mm.So bubble chi of particle diameter Very little differ greatly with floc particle, be unfavorable for adhesive attraction, affect air-flotation process effect;For saline sewage, due to salt in sewage Content is high, uses heterogeneous air-dissolving air-float to process, easily causes the problem such as air dissolved pump fouling, bubble release blocking.
