Description

A kind of complex microbial inoculum for deodorization
Technical field
The invention belongs to environmental protection and microorganism field, and in particular to be a kind of complex microbial inoculum for deodorization and Its preparation method.
Background technology
With the development and the improvement of people's living standards of industrial and agricultural production, pollutant caused by the mankind is continuously increased, special It is not that since the last century, the mankind destroy the hair at full speed for having brought social civilization and science and technology with large-scale environmental protection Exhibition, substantial amounts of soil, water body are by different degrees of pollution so that the benign cycle of ecological environment receives serious influence And destruction, also cause and cause harm to the health of the mankind and self-growth, environmental pollution increasingly becomes being total to for every country With one of problem, environmental pollution has become the significant problem of current international community with protection, right especially in developing country The control of environmental pollution has reached very urgent stage.A major reason for causing pollution is a large amount of of municipal wastewater Discharge, according to statistics, always the company of discharge is about annual 34500000000 tons to China's municipal wastewater, and wherein sanitary sewage accounts for more than 30%, life COD, BOD in sewage5Severe overweight.A kind of foul smell is given out in family bathroom space, drain of kitchen for various reasons, is made People's nausea, dizziness, or even vomiting, directly affects the life of people, jeopardize the health of people.Therefore, the control of malodor source Have become one of environmental problem for being badly in need of solving.
Deodorant mainly includes physical deodorization agent, chemical deodorizing agent, microbial deodorant, plant deodorant and compound removed Smelly dose.Wherein, stink substance is mainly adsorbed onto in absorbent hole by Physical deodorization by adsorbent, during Physical deodorization deodorization Between it is fast, but cost is higher, and adsorbent can not reuse, and the adsorbent containing stink substance is not easily recycled, and is easily caused Secondary pollution.Chemical method mainly mitigates stench, wherein chemical deodorizing agent by using chemical deodorizing material and aromatic substance Use can not thoroughly remove odorant, aromatic can bring unpleasant odour because fragrance scent is too strong.Microbial deodorant Agent mainly utilizes microorganism the odorant source on rubbish surface can be used for microorganism itself, is lived by microbial metabolism It is dynamic to make its degraded, in general, multiple-microorganism collective effect is more beneficial for absorbing, decompose caused by SO2、H2S、CH4Deng stench The pernicious gas of taste, meanwhile, multiple-microorganism can produce inorganic acid, form the acyclic acidic for being unfavorable for putrefactive microorganisms life Border, and fundamentally degrade and the material of foul gas is produced when decomposing, this is also that EM bacterium obtain applications well effect in terms of deodorization One of the reason for fruit.
The foul smell source on rubbish or sanitary sewage surface can be removed to a certain extent using microbial bacterial agent, but using micro- Biological treatment equally exists some problems, for example, deodorizing effect can not continue, so as to result in the need for repeatedly uninterruptedly using micro- life Thing deodorant carries out rubbish deodorization, causes substantial amounts of manpower and materials and wastes, and therefore, there is a kind of deodorization duration length to be supplied Complex microbial inoculum to adapt to the requirement of environmental protection.
The content of the invention
It is an object of the invention to provide a kind of complex microbial inoculum for deodorization, the complex microbial inoculum master There is kluyveromyces marxianus bacterium, the zymotic fluid of EM bacterium mixes, complex microbial inoculum good deodorization effect of the invention, The deodorization duration is grown, it is possible to reduce complex microbial inoculum application times, saves labour.
Another object of the present invention is to provide the application of the complex microbial inoculum, the complex microbial inoculum can It is widely used in the deodorization of rubbish heap, lavatory, kitchen, sanitary sewage surface.
Another object of the present invention is in the preparation method with providing the complex microbial inoculum.
To reach above-mentioned purpose, the present invention adopts the following technical scheme that:
A kind of complex microbial inoculum, it mainly includes yeast strain, the zymotic fluid of EM bacterium mixes.
Wherein, the yeast strain is kluyveromyces marxianus.
The preparation method of the complex microbial inoculum is:
A:The preparation of yeast strain ferments liquid;
B:The preparation of EM bacterial strain fermentation liquors;
C:By yeast strain ferments liquid and EM bacterial strain fermentation liquors using volume ratio as 0.2-0.5:1 volume ratio is well mixed, It can be prepared by complex microbial inoculum of the present invention.
Further, the preparation method of the yeast strain ferments liquid is:The activation of kluyveromyces marxianus bacterium is followed by Kind at 28-35 DEG C, cultivates 48-72h in the fluid nutrient medium of culture yeasts bacterium in 120-200r/min shaking tables, passes through The concentration of kluyveromyces marxianus is adjusted to 1 × 10 with sterilized water after counting7-1×109CFU/mL。
Wherein, the fluid nutrient medium is YPD culture mediums.
Further, the preparation method of the EM zymotic fluids is:0.2-0.5Kg brown sugar is added in warm water, is sufficiently stirred Dissolving, when being cooled to room temperature, 6-10g EM strains are added, are sealed by fermentation 5-8 days at a temperature of 25-35 DEG C, obtain EM fermentations Liquid.
Further, more preferably type of service is microbial fermentation solution to complex microbial inoculum of the invention, can also be led to Cross conventional method and be processed into freeze-dried powder, or other composite bacteria agents are combined into other deodorant.
Further, other deodorant can be chemical deodorizing agent, plant source deodorant etc..
Further, complex microbial inoculum of the invention regards its use state, can be made by way of launching, spraying With.
Microbial strains used herein can be bought by conventional commercial means and be obtained, for example, the present invention is implemented The purchase of kluyveromyces marxianus bacterium grinds bio tech ltd from Shanghai one used in example, and the EM bacterium are revived purchased from Shandong Ke Han bioengineering limited company.
Compared with prior art, deodorizing microorganism composite bacteria agent of the invention has the beneficial effect that:
1st, while complex microbial inoculum of the invention quickly can go to eliminate the unusual smell, odoriferous thing can be thoroughly eliminated, It is capable of the maintenance deodouring effect of long period;
2nd, complex microbial inoculum nonhazardous of the invention effect, has no irritating odor, will not cause secondary pollution;
3rd, complex microbial inoculum of the invention is due to efficiency time length, first use, so that it may prevent and kill off foul smell well Source, be advantageous to save labour;
4th, complex microbial inoculum raw material of the invention is easy to get, and preparation technology is simple, and production cost is relatively low.
