Description
Technical field
The utility model relates to a kind of bacteria filter systems for handling garbage odor, are mainly used at domestic garbage resource
Science and engineering factory or house refuse terminal.
Background technique
In recent years, China's rubbish output is growing day by day, if a large amount of domestic waste cannot be handled effectively,
Water body, atmosphere, soil etc. to urban ecological environment and periphery is caused into serious pollution, and is caused a large amount of useful in rubbish
The wasting of resources.And people have gradually recognized that part rubbish is using " wealth ", therefore Reducing Municipal Solid Waste, money
Source, the harmless treatment attention more and more by government and the public.In March, 2017, forwarding country, General Office of the State Council hair
Exhibition reform committee, house town and country construction portion " categorized consumer waste system embodiment " push categorized consumer waste, promote resource
It recycles.Many garbage as resource projects also get up accordingly by construction.
Garbage as resource processing can carry out recycling and reusing to resources most in rubbish, turn waste into wealth, changing evil is
Benefit really realizes the final minimizing for realizing rubbish, recycling and innoxious.For example come out the separating plastic in rubbish, it moulds
Cycling and reutilization after material is granulated；Metal in rubbish is sorted out, cycling and reutilization after smelting；Glass is sorted out, is returned
Furnace recycling etc..
However organic matter in garbage contains the compositions such as N, S, under bacteria metabolism effect, can generate NH3, H2S etc.
The features such as foul smell composition, these foreign odor molecules all have big volatility, low boiling point, big smell characterization value.Rubbish is at recycling
A large amount of foul gas can be generated during reason, cause secondary environmental pollution.
The method of present conventional treatment refuse odor is plant liquid spraying method or absorption method.Plant liquid spraying method is to enter
Deodorization particulate in exhaust gas actively captures the odorous gas molecule in air, and stink particle is wrapped up, and passes through combined reaction
Decomposition smell molecule.The plant maintenance of plant liquid spraying method is easy, but treatment effect is unstable and consumes vegetation water.Absorption method
It is that malodor molecules are adsorbed using porous media, equipment is simple, and it is at low cost but adsorption effect is unstable, show as initial stage
Good, odor removal efficient reduces rapidly after operation, and small to concentration, and the big stink of odor strength, fishy smell are without positive effect.

The principle of biological deodorizing be odor pollution object is absorbed using the biodegradation of microorganism and is degraded from
And achieve the purpose that deodorization.Foul smell utilizes microbial cell pair by wet, porous and full of active microorganism biologic packing material
Absorption, absorption and the degradation function of pollutant, the cell individual of microorganism is small, surface area is big, strong adsorption, metabolic type multiplicity
The characteristics of, CO is resolved into after pollutant is adsorbed2、H2O、H2SO4、HNO3Etc. simple inorganic matter.The present embodiment is washed using leading portion
The compound action with biological treatment is washed, foul smell tower washed first removes the soluble foul smell molecule of a part, enters back into biology
Filter tank, by the effect of microorganism by contaminant degradation therein, detailed process is: when foul smell pass through biologic packing material gap, can
Those of nutrient source microbial flora is obtained from pollutant, under the conditions ofs suitable temperature, humidity, pH value etc., it will obtain
Fast-growth, breeding, and biomembrane is formed in filler surface, when foul smell is by the way that therebetween, organic matter is by the water layer of biofilm surface
By microorganism adsorption and degradation after absorption.The essence of pollutant removal be absorbed by the micro-organisms using foul smell as nutriment, generation
It thanks and utilizes.This process is the mutually coordinated process of microorganism, it is by physics, chemistry, physical chemistry and biochemistry
Reaction is formed.Biological deodorizing can be expressed as: pollutant+O2→ cell metabolite+CO2+H2O。
A kind of working method for the bacteria filter system handling garbage odor:
Foul smell from gas access 14 enter tower body 11, from bottom to top pass through filler 12, spray liquid then passes through liquid distribution
Spray head on device is uniformly sprayed onto filler 12, is flowed downward along 12 surface of filler, into cyclic water tank 16.Due to rising
Foul smell and the spray liquid of decline constantly contacted in filler 12, rise water-soluble gas material concentration in foul smell more and more
It is low, blower 2, which is deodorant, after pushing up to tower body 11 is extracted into gas distributor 7.Foul smell tentatively removes the water in foul smell in scrubbing tower 1
Insoluble gas substance, such as: dust, NH3、H2S、CH3SH and organic odorants etc., and adjust the temperature of foul smell, pH value
And humidity, it creates conditions for subsequent biofilter 3.
Foul smell uniformly enters in ventilation duct 4 after the distribution of gas distributor 7, then is entered by ventilation duct air outlet 41
Inside biofilter 3, foul smell comes into full contact with the biologic packing material with certain humidity；Pollutant in foul smell is first by biologic packing material
The water layer of the biofilm surface on surface layer absorbs, and the pollutant in water layer is re-used as nutriment by the microorganism in biologic packing material point
Solution utilizes, to eliminate stink；The top that gas after biological decomposition directly passes through biofilter 3 is discharged into atmosphere.Carefully
Stone concrete layer 5 keeps apart biologic packing material and the ventilation duct air outlet 41 on ventilation duct 4, avoids biologic packing material blocking ventilation
Pipe air outlet 41, while the moisture filter that can leak biofilter 3 is into ventilation duct 4 again for pea gravel concreten layer 5, ventilation duct 4
In water via drain outlet 31 be discharged, recycle after processing, avoid infiltration secondary pollution is caused to environment.
In the above process, the spray liquid in scrubbing tower can eliminate the object concentrated in foul smell in such a way that water absorbs
Matter, usually dust, acid micropollutants or chemical substance need to close by addition if pollutant can hardly be dissolved in water
The reagent of suitable acidity or alkalinity is made a return journey depollution object, and the contaminant compound of generation will be deposited in cyclic water tank 16.
It is provided with temperature probe and humidity probe in biofilter 3, and is provided with irrigation system to guarantee biomass growth
With suitable humidity.
In addition, it should be noted that, the specific embodiments described in this specification, the shape of parts and components are named
Title etc. can be different, and above content is only to the utility model structure example explanation described in this specification.
All equivalence changes or simple change done according to structure, feature and principle described in the concept of the patent of the utility model, are wrapped
