Description
Technical field:
The present invention relates to exhaust gas, dust processing technology field, and in particular to a kind of bioprocessing industry exhaust gas, dust are
System and method.
Background technique:
Atmosphere pollution at present has had reached quite serious stage, and industry is an important sources of atmosphere pollution.Industry
The pollutant kind being discharged into atmosphere is various, have flue dust, sulfur oxide, nitrogen oxide, organic compound, halide,
Carbon compound etc..Wherein have plenty of flue dust, has plenty of gas.It is analyzed from form, industrial waste gas can be divided into graininess exhaust gas
Gentle state property exhaust gas.The active carbon adsorption of principle of industrial waste gas processing, Production by Catalytic Combustion Process, plasma-catalysis oxidation
A variety of principles such as method, condensing recovery, absorption.Active carbon adsorption belongs to physical transfer, utilizes the porosity of active carbon, will
Pollutant is transferred to another by the organic pollutant adsorption storage in exhaust gas between the hole of active carbon from an object
It is transferred to another place in a object or by pollutant from a place, is substantially that there is no right for pollutant transfer
The processing of exhaust gas progress essence.And the active carbon after being saturated belongs to dangerous solid waste, replacement frequency is high, consumption pole
Greatly, such method is gradually eliminated by environmental protection industry (epi).Production by Catalytic Combustion Process refers to organic exhaust gas in the catalytic action of catalyst
Under, 300~400 DEG C at a temperature of burn.The method mostly uses platinum of with higher heat-resisting and antitoxin performance etc. expensive
The catalyst of metal, it is at high cost to guarantee the activity of catalyst;Two-stage treatment process is had to pass through when burning processing, it must also be right
Organic exhaust gas carries out pre-add heat treatment to maintain catalysis ignition temperature, and energy consumption is high, operating cost is high;It simultaneously must strict control combustion
Temperature is burnt to generate other harmful substances when preventing and burning, this not only proposes more requirements to the technology of incinerator itself,
And it is difficult to absolute guarantee's substance without secondary pollution and generates;Benzene-like compounds and oxidation category, stench class compound are urged when burning
Changing burning has great hidden danger to safety in production, and there is also the potential dangers of explosion, especially effumability fuel gas particle
Property exhaust gas.Plasma-catalytic oxidation is the strong oxidation using ozone, by the organic exhaust gas object oxidation point in exhaust gas
The chemical substance and inorganic matter of Xie Weixin.Using ozone strong oxidation when, excessive ozone must be passed through, and excessive smelly
Oxygen can generate biggish harm to human health with exhaust emissions into air;And ozone generator is needed in forceful electric power
Ozone is generated under the action of pressure, under the action of strong voltage, ozone generating apparatus is also easy to produce electric spark, and it is hidden that there are security against fires
Suffer from;And during Strong oxdiative, the product of oxidation reaction has uncertainty, easily generate it is new, more intractable two
Secondary pollutant.Processing method relatively above, biologic treating technique have its unique advantage, it is to utilize microorganism by Industry Waste
Gas is converted into harmless or available substance.However, being directed to the biologic treating technique of exhaust gas not on the market at present
Obtain satisfactory effect, it is difficult to realize efficient, the completely innoxious processing to exhaust gas;And irrational mix
So that equipment volume is huge, strength disposal is small, and being applied in production not only will increase production cost and can also cause to production efficiency
It influences.
Summary of the invention:
The object of the present invention is to provide the system and method for a kind of bioprocessing industry exhaust gas, dust, using biological treatment
Method, physics, the technique that combines of chemistry can be effectively removed exhaust gas, the pollutant in dust according to different exhaust gas, dust
Matter realizes that efficient, the completely innoxious deep purifying to exhaust gas, dust is handled, and purified exhaust gas is non-toxic and tasteless, and realization reaches
Mark discharge, no waste water and the discharge of various impurity dangerous waste substances, do not generate secondary pollution, safe and reliable and this process operation cost
Low, without often more conversion materials, annual maintenance only adds some microbial nutrient solutions, keeps an eye on, can be transported steadily in the long term without special messenger
Row.

The raw green bacterium of mud, the dry bacterium of sulphur, reducing bacteria are laid in biological culture pond, it is main to select in filler containing acid, basic active filler.
Such as utilize microorganism flue gas desulfurization: using autotrophic microbe, being acted on by the indirect oxidation of sulphur removal microorganism, it will
SO in flue gas2It is oxidized to sulfuric acid, microbial bacteria therefrom obtains energy and nutrient.
The microorganisms such as sulfate reducing bacteria are using organic matter as electron donor, using sulphite and sulfate as final electronics
Receptor is simultaneously reduced to sulfide.It is alienation sulfate reduction, the H of generation by the above biochemical reaction process2S etc.
Sulfide can be used as the electron donor of Thiobacillus and photosynthetic bacteria.
It denitrogenates: being acted on using the anaerobic respiration of denitrifying bacterium, nitrogen oxide NOx passes through denitrification in denitrification process
Bacterium is converted into N through catabolism2, adsorbed by anabolism by denitrifying bacterium and solid phase carrier, then in denitrifying bacterium
In, N is reduced to by the effect of nitric-oxide reductase2。
Mass transport process and biochemical reaction process: nitrogen oxide NOx is transferred in liquid phase or solid phase surface liquid film simultaneously by gas phase
And it is removed and purifies by microorganism in liquid phase or solid phase surface.
Beneficial effects of the present invention are as follows:
1) technique that the present invention is combined using biological treatment, physics, chemistry, can effectively go according to different exhaust gas
Polluter in removing exhaust gas, the polluter in exhaust gas, dust converted under the action of microorganism, degraded, absorbed,
Removal realizes and handles efficient, the completely innoxious deep purifying of exhaust gas that purified exhaust gas is non-toxic and tasteless, realizes up to standard
Discharge, no waste water and the discharge of various impurity dangerous waste substances, do not generate secondary pollution, and safe and reliable and this process operation is at low cost,
Without often more conversion materials, annual maintenance only adds some microbial nutrient solutions, keeps an eye on, can be run steadily in the long term without special messenger.
2) present invention cultivates microorganism using the supply source original place of industrial waste gas, dust, i.e. industrial waste gas, dust serves as micro-
The fuel (carbon source, the energy) of biology, and utilize the effect of microorganism carries out oxygenolysis and same to exhaust gas, dust pollution object
Change effect, is eventually converted into harmless compound, reaches bioprocessing industry exhaust gas, dust optimum efficiency.
