Abstract
The invention discloses a functional biocatalyst for biogas fermentation and a method for fermenting using the catalyst. The catalyst comprises 1-3 parts of a microbial composite bacterial agent, 100 parts of hydrolase accelerant and 61-329 parts of mineral nutrient accelerant, wherein the mineral nutrient accelerant is one or more of microcrystalline ground phosphate rock, microcrystalline zeolite powder, microcrystalline calcium carbonate powder, urea, phosphate, bentonite and active carbon. The biogas fermentation method comprises the following steps: performing biogas fermentation by using 350-650 parts of poultry excrement, 100-300 parts of inoculum and 163-430 parts of functional biocatalyst while controlling the moisture content of the poultry excrement at 75-85%; and stirring and mixing for fermentation, wherein the concentration of the whole original feed liquid is 7-12%. In the invention, apart from the supplement of the nutritive elements for biogas fermentation, the effects of deodorization and inhibition of pathogenic microorganisms are realized through the functional complementation effect among the adsorption of an adsorbent, ion exchange, biodegradation and membrane filtration so that the biocatalyst is harmless; and moreover, the preparation technology has the advantages of simple process, easiness in operation, good effect, low investment, no pollution and wide application value.
Description
Technical field
The invention belongs to biogas fermentation technical field, relate to a kind of containing the multi-functional biological catalyst of micritization ground phosphate rock and utilize catalyzer to carry out the method for biogas fermentation.
Background technology
According to State Environmental Protection Administration, the concentrated province of 23, whole nation livestock and poultry farms in scale, city's investigation were shown in 2000; nineteen ninety-five; the whole nation then COD total emission volumn of trade effluent is 768.37 ten thousand tons; and the waste discharge amount of livestock and poultry breeding industry is converted to COD, be 728.6 ten thousand tons, approach the COD total emission volumn of national trade effluent.1999, the generation of China's animal waste was about 1,900,000,000 tons, was 2.4 times of industrial solid wastes.2000, national feces of livestock and poultry year generation reached approximately 17.3 hundred million tons, be 2.7 times of trade waste.The organic pollutant containing in animal waste, only mono-of COD just reaches 7,118 ten thousand tons, considerably beyond industry and the COD summation of Sewage Pollution thing.But these feces of livestock and poultry and sewage are good biogas fermentation materials, fully utilize these wastes, realize the recycling of waste, turn waste into wealth, turn harm into good, have important practical significance.
Anaerobic methane fermenting process is that a methanogen and non-methanogen interact, the homeostasis process of restriction mutually.Multiple organic matter, under certain temperature, humidity, potential of hydrogen and anaerobic condition, is decomposed and is hydrolyzed by microorganism, and insoluble organic macromolecule is resolved into small molecules, for producing hydrogen, acetogen and methanogen utilization, finally produces a kind of inflammable gas.Its main component is CH
4, be secondly CO
2, H
2s, nitrogen and other compositions.
Marsh gas fermentation processes is in fact microorganism, metabolism and energy conversion process, and in catabolic process, biogas microorganism obtains energy and material, and to meet self Growth and reproduction, most of Substance Transformation is CH simultaneously
4and CO
2.Anaerobically fermenting microbial growth needs certain nutritive substance, and C, N, P to be methane fermentating microorganism grow three kinds of nutritive elements that need most.Carbohydrate in organism is the C element nutrition of bacterium, and the organonitrogen in organism is the N element nutrition of bacterium, and the nutrition of P element is added by external source.Except guaranteeing, necessary anaerobically fermenting nutritive element, to need comparatively suitable C/N ratio in marsh gas fermentation processes, its scope is generally 10:1～30:1.In practical engineering application, generally take to add the method for crop material to regulate C/N value to reaching better aerogenesis effect in fowl and animal excrement (pig manure, cow dung, chicken manure etc.).For example, cornstalk, rice straw, Cotton Stalk, straw and Herba Eichhorniae are mixed with cow dung, improve anaerobically fermenting environment, can improve 10%～80% biogas output.But because a large amount of Mierocrystalline celluloses, hemicellulose and xylogen are present in plant stem-leaf or poultry manure, xylogen and hemicellulose are with covalent bonds, cellulosic molecule is embedded in wherein, form a kind of natural cover for defense, make enzyme be difficult for contacting with cellulosic molecule, be difficult to by acid or enzymic hydrolysis, cause stalk when anaerobically fermenting, to decompose slowly.C/N value generally, in 25:1-30:1 left and right, does not need the carbon source or the nitrogenous source that add other just can meet the required C/N ratio of anaerobically fermenting.
In addition in biogas fermentation engineering practice, also there is, the problem of some ubiquities.For example, (1) biogas output cold season obviously reduces, and the marsh gas raw materials gas production rate of same quantity is usually not as good as 1/3rd of summer; (2) biogas fermentation material can not get decomposing fully and utilizing in pond, and actual biogas turnover ratio (raw material factor of created gase) is lower.In order to improve decomposition utilization ratio and the gas production rate of biogas fermentation material, all extremely focus on the quality and quantity of methanogen floras (anaerobic sludge) in biogas both at home and abroad.Research shows: methanogen can only utilize ammonium nitrogen as nitrogenous source, and can not utilize complicated nitride.Urea facile hydrolysis is ammonium nitrogen, therefore can provide sufficient nitrogenous source for methanogen and methane-oxidizing bacteria.Adding urea and Secondary ammonium phosphate etc. can provide required nutritive element for anaerobically fermenting, improves the gas production rate of biogas fermentation.Add Rock Phosphate (72Min BPL) than elemental phosphorous better effects if.When effectively utilizing Mineral resources, be conducive to the raising of the propagation of microorganism and the surge capability of reactor.Further research shows: add sorbent material and also can improve aerogenesis effect.Major cause be sorbent material by germs collect, increase microbe density, simultaneously can keep the environment favourable to microorganism growth, thereby allow microorganism degradation of organic substances matter better, the consumption of quickening volatile acid, raising gas production rate.In addition, sorbent material also can reduce heavy metal content in methane fermentation system.
We think, except increasing the quality and quantity of methanogen floras, should add a kind of multifunctional bio catalyzer for biogas fermentation, improve environment and the metabolic function of bacterial classification, and organism is more thoroughly decomposed, and improve the gas production rate of biogas fermentation.Practice shows: for process solid content higher, containing the biogas fermentation material of more more difficult decomposing organic matter, take this measure to seem particularly important.
