Description
Technical field
The utility model belongs to biogas utilization technical field, relates in particular to a kind of biogas recirculation formula anaerobically fermenting fertilizer system processed.
Background technology
Biogas be organic substance under anaerobic, a kind of mixed gas generating through the fermentative action of microorganism.Because this gas is swampy at first, so be called biogas.The various organism such as human and animal excreta, stalk, sewage in airtight methane-generating pit, at anaerobism (there is no oxygen) condition bottom fermentation, the methane fermentating microorganism decomposition and inversion that class is various, thereby produce biogas.Biogas is a kind of mixed gas, can burn.Biogas is the inflammable gas that organism produces through microbiological anaerobic digestion.
Biogas is the mixture of multiple gases, and generally, containing methane 50～70%, all the other are carbonic acid gas and a small amount of nitrogen, hydrogen and hydrogen sulfide etc.Its characteristic is similar to Sweet natural gas.In air as contain 8.6～20.8%(by volume) biogas time, will form volatile mixed gas.Biogas except direct burning for cooking, dry agricultural byproducts, heating, illumination and gas welding etc., also can make the industrial chemicals such as the fuel of oil engine and methanol, formalin, tetracol phenixin.Feed liquid and the sediment of after firedamp gas equipment fermentation, discharging, contain more rich nutritive substance, can be used as fertilizer and feed.
Biogas is some organic substances, and under certain temperature, humidity, acidity condition, isolated air (as with methane-generating pit), through microbial process (fermentation) and the inflammable gas of generation.It contains a small amount of hydrogen sulfide, so stink slightly.Fermentation is complicated biochemical change, has many microorganisms to participate in.Reaction roughly divides two stages: (1) microorganism becomes simple material the carbohydrate in complicated organic substance, fat, protein degradation, as lower fatty acid, alcohol, aldehyde, carbonic acid gas, ammonia, hydrogen and hydrogen sulfide etc.(2), by the effect of methane bacterial classification, make some simple materials become methane.To normally produce biogas, be necessary for microorganism and create good condition, make it can survive, breed.Methane-generating pit must meet multiple condition.First, methane-generating pit is airtight.Organic substance is fermented into biogas, is the result of multiple anerobe activity, therefore will cause the anaerobic environment of an anerobe activity.To note isolated air building when methane-generating pit, airtight, do not seep water.Secondly, in methane-generating pit, to maintain 20～40 ℃ because conventionally at this temperature factor of created gase the highest.The 3rd, methane-generating pit will have sufficient nutrient.Microorganism will survive, breed, and must from fermented material, draw nutrient.In the fermentation raw material of methane-generating pit, human and animal excreta can provide nitrogen element, and the Mierocrystalline celluloses such as the stalk of farm crop can provide carbon.The 4th, fermentation raw material will contain suitable quantity of water, and moisture 80% left and right in the fermentation raw material of general requirement methane-generating pit is too much or very few all unfavorable to aerogenesis.The 5th, the pH value general control of methane-generating pit is 7～8.5.
In the last few years, biogas was progressively promoted and was come in vast rural area as a kind of clean energy, had following effect for rural area: (1) biogas can not only solve rural energy problem, and can increase Organic Fertilizer Resources, improve quality and increase fertilizer efficiency, thereby improve crop yield, improvement soil; (2) use biogas, can save in a large number the organism such as stalk, hay, to be used for producing animal feed and as paper making raw material and handicraft starting material; (3) set up biogas and can reduce the phenomenon of haggling trees and disorderly stripping vegetation, protection vegetation, makes agricultural production system progressively to cycle development; (4) set up biogas, be conducive to the generation of environment purification and minimizing disease.This is that the germ mortality in human and animal excreta, improves environmental health condition because in methane-generating pit fermentative processing process; (5) with the biogas illumination of cooking, both saved household economy spending, the work time of saving again housewife, reduce labour intensity; (6) use natural pond fertilizer, improve agricultural product quality and quality, increase income, reduce agricultural pollution, for Agricultural product without pollution lays the foundation.Conventional material cycle utilize the type ecosystem mainly contain plant husbandry-aquaculture-biogas engineering three in conjunction with, aquaculture-fishery-plant husbandry three in conjunction with and the type such as the ecological engineering of aquaculture-fishery-forestry three combinations.It is the most general that wherein the material cycle of plant husbandry-aquaculture-biogas engineering three combinations is utilized the application of type ecological engineering, and effect is best, also applies wider.
But the raw material in the anaerobically fermenting pond in existing biogas fermentation treatment system exists and stirs inhomogeneous problem, makes raw material not carry out fully anaerobically fermenting operation, and this just has influence on biogas production efficiency and biogas output.
