For the ease of the understanding of those skilled in the art, the present invention is made further below with reference to embodiment and attached drawing
Bright, the content that embodiment refers to not is limitation of the invention.The present invention is described in detail below in conjunction with attached drawing.
Embodiment one
A kind of VOCS waste gas processing method of micro-nano oxygen bubbles synergistic carriers biology, including the following step successively carried out
Suddenly:
A:Mixing water and oxygen, and pressurize to the mixture of water and oxygen, so that it is micro- less than 30 to form diameter in water
The oxygen bubbles of rice;
B:It boosts to the mixture of water and oxygen, so that generating nanoscale oxygen bubbles in water, forms micro-nano oxygen
Air-bubble;
C:It is soaked to micro-nano oxygen to ionize, it is soaked to form the micro-nano oxygen of ionization;
D:Using the VOCS exhaust gas for ionizing micro-nano oxygen bubbles water spray and rising flowing, ionize micro-nano oxygen it is soaked with
Become water after VOCS exhaust gas contact;
E:Utilize VOCS exhaust gas of the micro-nano oxygen bubbles water spray of ionization generated in step C after step D spray, ionization
Micro-nano oxygen it is soaked with VOCS exhaust gas contact after become water;
F:The water that collection step D and step E is generated, circulation step A to step E;
G:Enable the VOCS exhaust gas after step E spray by being provided with the bio-carrier of flora.
Micro-nano oxygen bubbles surface band positive and negative charge, and relative to common blister, institute's band positive and negative charge is relatively high, benefit
With micro-nano oxygen bubbles with positive elecrtonegativity, can adsorb with plus-minus electric substance.VOCS exhaust gas and the micro-nano oxygen bubbles of ionization
After water contact, all hydrophobicity finely ground particle substances can be adsorbed on the surface of micro-nano oxygen bubbles, adsorpting polymerization in VOCS exhaust gas
The macromolecular resin formed afterwards is not soluble in water, therefore can precipitate and fall and separate with VOCS exhaust gas.User periodically recycles whereabouts
Macromolecular resin.
In the case where continuous shrink, the density of the charge of electric double layer can increase rapidly 10um micro-nano oxygen bubbles below
Height, when bubbles burst, the positive and negative charge for having reached high concentration, which sparks, discharges the energy of savings, generates a large amount of
Radical ion, such as oxonium ion, hydrogen ion, hydroxyl ion.And hydroxyl radical free radical therein has very strong oxidation,
Purification reduction effect well can be played with some organic pollutants for being difficult to degrade of oxygenolysis.Micro-nano oxygen bubbles rupture
When, the tension force effect of walls will discharge huge explosion energy, ultrasonic energy, and this ultrasonic wave is made with very strong sterilization
With can produce a large amount of anion, destroy pollutant and be covalently keyed, the chemical bond that can also be destroyed inside pollutant connects
It connects, completes oxidative degradation pollutant.When VOCS exhaust gas continues flowing and second spray soaked by the micro-nano oxygen of ionization
When, VOCS substance in VOCS exhaust gas by the continuous oxygenolysis of micro-nano oxygen bubbles at small molecule or monomolecular substance, while it is micro-
The ultrasonic energy that nano oxygen bubbles burst generates sterilizes VOCS exhaust gas, to realize purification.In VOCS exhaust gas still at this time
There is part VOCS substance not to be decomposed, therefore military order VOCS exhaust gas utilizes the flora pair on bio-carrier by bio-carrier
VOCS adsorbed, nitrification and denitrification, final 95% or more VOCS substance be oxidized be reduced to carbon dioxide, water, oxygen,
Hydrogen realizes that VOCS waste gas purification handles qualified discharge, and can prevent secondary pollution.
During processing, VOCS exhaust gas is made to rise flowing using the positive pressures pressurizing device such as air blower, it is useless compared to VOCS
Gas nature Doenward flow, the flow velocity of VOCS exhaust gas is slower, and soaked time of contact is also longer with micro-nano oxygen, effectively improves net
Change effect.
Micro-nano oxygen ducks in drink ramp after can make oxygen from the water surface scatter and disappear, so as to cause micro-nano in water
Oxygen bubbles content is few, then causes to purify insufficient.Micro-nano oxygen in the present invention is soaked sprayed before by magnetic field
Ionization, therefore the ion that the micro-nano oxygen bubbles formed is generated with ionization, so that micro-nano oxygen bubbles forms ion air mass.
Under the action of these ions, bubble surface tension gradually increases, and keeps the diameter of bubble smaller and smaller, and with the dissolution of ion
And it is gradually dissolved in water, and this ionization power and surface tension have completely or partially resisted liquid and floated to bubble generation
Power effect, so that bubble is steadily stayed in liquid, be effectively ensured micro-nano oxygen it is soaked in have higher micro-nano oxygen
Air bubble content, to improve purification efficiency and clean-up effect.
Further, the bio-carrier in step G is polyurethane foamed blocks.Polyurethane foamed blocks shape is similar to sponge, hole
Cave specific surface area reaches 250 meters squared per grams or more, provides 1 to microorganism:The habitat of 250 huge growth and breeding.By biology
The carrier biofilm that carrier is formed can be carried out biofiltration, decompose and convert the harmful substance in VOCS exhaust gas.
Further, flora used in step G is PSB bacterium, B350 bacterium and B110 bacterium.PSB bacterium is facultative type mushroom:
Such as swamp Rhodopseudomonas, green pseudomonas, Rhodococcus sp, it can utilize and decompose ammonia, hydrogen sulfide, mercaptan.B350 bacterium is facultative type
Mushroom:Such as Nocard's bacillus, Bacillus foecalis alkaligenes, aspergillus niger, can utilize and Decomposition of benzene, aldehyde, Trimethylamine, furfural.B110 bacterium is preferably
Oxygen type mushroom:Such as bacillus subtilis, bacillus megaterium, saccharomyces cerevisiae, can utilize with decompose saturated hydrocarbons, cyclic hydrocarbon, ether, ketone,
Ester, phenolic compounds.
Further, the number ratio of PSB bacterium, B350 bacterium and B110 bacterium is 1:2:1.5.Can effectively prevent flora it
Between swallow mutually, guarantee that PSB bacterium, B350 bacterium and B110 bacterium can steadily coexist on bio-carrier.
With the composition before four groups of VOCS exhaust-gas treatments, composition compares following table with treated, it is seen that various in VOCS
Organic VOCS exhaust gas constituents removal rate reaches 90-99%, and average removal rate is 95% or more, and standard biologic liquid spray process
Removal rate is usual<50%, originally water spray removal rate is usual<45%, it is seen that method treatment effect provided by the invention it is more preferable and
Treatment effeciency is higher.
