Description

Composite fungus agent of a kind of COD that degrades and preparation method thereof
Technical field
The present invention relates to microbiobacterial agent field, specifically the composite fungus agent and preparation method thereof of a kind of COD that degrades.
Background technology
Well-known, current mankind is faced with multiple crisis, such as crisis in food, energy shortage, resource scarcity, ecological degeneration and Population explosion etc.After the mankind enter 21 century, utilize the unlimited Biological resources epoch and a series of new problems produced by running into from utilizing the limited mineral wealth epoch to be transitioned into.Because microorganism cells is that one larger than face amount, biochemical conversion ability strong, can carries out the Living system of quick self-replacation; and they also have the diversity of species, heredity, metabolism and ecotype, make them can play its irreplaceable unique effect in the various crises solving facing mankind.
Industrial pollution source: trade effluent is the important source of pollution in waters, the features such as the amount of having is large, area is wide, complicated component, toxicity are large, should not purify, difficult.Agricultural pollution source: agricultural pollution source comprises excrement of animals, agricultural chemicals, chemical fertilizer etc.China is one of country that soil erosion is the fastest in the world, every chronology soil number of dropouts about 5,000,000,000 tons, the lake of 2/3rds is subject to the harm of eutrophication in various degree, causes algae and other biological distorted proliferation, cause the change of water transparency and dissolved oxygen, thus cause water quality deterioration.Domestic pollution source: the various washing composition that domestic pollution source mainly uses in urban life and sewage, rubbish, ight soil etc., mostly be nontoxic inorganic salts, many containing nitrogen phosphate and sulfur in sanitary sewage, bacterium of curing the disease is many.Existing sewage disposal process by activated sludge process cost is high, and COD (chemical oxygen demand (COD), Chemical Oxygen Demand) clearance is undesirable.
Microbial preparation was existing in water surrounding improvement in recent years applied, but there is a lot of problem, as some microorganisms can not produce enzyme, the small molecules nutritive substance of just simple absorption water body, effectively can not promote the material cycle of water body environment, effectiveness comparison is slow.Bacterial classification is single, and the effect of each microorganism in the link of water body material cycle is different, and show through experiment, composite bacteria effect and processing efficiency are much larger than single culture.
Summary of the invention
The object of the present invention is to provide that a kind of adaptive capacity to environment is strong, COD of sewage is removed and can be reached composite fungus agent of the degraded COD of 95% and preparation method thereof, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
To degrade a composite fungus agent of COD, be made up of the following bacterium liquid according to volume ratio: candida tropicalis 9-11%, Candida parapsilosis 9-11%, subtilis 28-32%, Bacillus licheniformis 28-32%, excrement intestines milk-acid bacteria 19-21%; And the bacterium number of each bacterium liquid is followed successively by: candida tropicalis 2.1 × 10 8-5.4 × 10 8individual/ml, Candida parapsilosis 2.3 × 10 8-5.8 × 10 8individual/ml, subtilis 5.5 × 10 8-9.6 × 10 8individual/ml, Bacillus licheniformis 5.0 × 10 8-9.8 × 10 8individual/ml, excrement intestines milk-acid bacteria 1.5 × 10 8-2.6 × 10 8individual/ml.
As the further scheme of the present invention: the composite fungus agent of described degraded COD, be made up of the following bacterium liquid according to volume ratio: candida tropicalis 10%, Candida parapsilosis 10%, subtilis 30%, Bacillus licheniformis 30%, excrement intestines milk-acid bacteria 20%.
The preparation method of the composite fungus agent of described degraded COD, is made up of following steps:
One, cultivate in organic abundant sewage substratum after candida tropicalis, Candida parapsilosis, subtilis, Bacillus licheniformis, excrement intestines milk-acid bacteria being inoculated in sterilizing respectively, obtain respective bacterium liquid; Be 30 DEG C in temperature, shaking speed is that the bacterium number being cultured to bacterium liquid under the condition of 200r/min reaches above-mentioned scope;
Two, above-mentioned bacterium liquid is mixed according to volume ratio, obtain composite fungus agent.
As the further scheme of the present invention: the steam sterilizing condition that step one prepares sewage in the sewage substratum of bacterium liquid is 121 DEG C, 30min.
As the further scheme of the present invention: the working conditions of composite fungus agent requires that sewage pH is 6.0-7.0, temperature 25-35 DEG C.
Strain characteristic selected by the present invention and function as follows:
1) subtilis, can produce amylase and bacillin, again can the organic matter such as degradation of polysaccharide class.
2) Bacillus licheniformis, can produce proteolytic enzyme, bacitracin etc., adapts to all kinds of Sewage Environment ability strong.
3) candida tropicalis, Candida parapsilosis, can produce proteolytic enzyme, and degraded multiple protein class is organic.
4) sausage stuffed mainly with bean starch paste milk-acid bacteria, can produce lactic acid class goods and materials, and the multiple macromole of effective acidication is organic, release small organic molecule matter.
Compared with prior art, the invention has the beneficial effects as follows: composite fungus agent prepared by the present invention adaptive capacity to environment is strong, be applicable to different areas microbial augmentation sewage disposal, be applicable to the sewage that all kinds of organic matters such as aquaculture wastewater, sanitary sewage and percolate class sewage are abundant, COD of sewage is removed can reach 95%.Solve existing sewage disposal process by activated sludge process cost high, the problem that COD clearance is undesirable.Described in specific as follows.
1) microorganism used can the multiple larger molecular organics of efficient degradation.Traditional active sludge contains multiple-microorganism, but superior microorganism Microflora is limited, can not reach the object of efficient degradation, and sludge sump laid down cost is high, and operation maintenance cost is high, to sewage organic matter degradation limited efficacy.
2) microorganism used is based on sewage ancestral home bacterium
Microorganism has certain environmental compatibility as all biologies, traditional microorganism great majority used are Lu Sheng, reach water body and can not adapt to water surrounding, therefore can not breed very soon, form dominant microflora, and ancestral home bacterium is separated from Sewage Environment, to Sewage Environment strong adaptability, artificial input can form dominant microflora rapidly later.
3) microorganism used can also produce microbiotic sample material
Selected microorganism can produce microbiotic sample material as genus bacillus, Bacillus licheniformis, has restraining effect to pathogenic bacterium.
4) microorganism selected by is the mixture of multiple-microorganism, and they have stronger specific aim and combination ability, not mutually exclusive in biologic packing material, mutually coordinates in sewage, and successful improves.Do not need complicated engineering process during use, directly throw in, easy to use.
