Description
Technical field
The utility model relates to a kind of little ecologic reactor that is used for marsh gas purifying.
Background technology
China is maximum in the world agriculture production state, annual hundred million tons of all kinds of crop material 6-7 that produce, and its utilization ratio is about 30%, and this wherein only accounts for 2.6% through the technical finesse utilization.Owing to can't utilize, taken a large amount of soils, all burn stalk in annual for this reason rural area, has caused serious topsoil, and initiation fire and influence motorway and the operating safety of civil aviaton.On the other hand, nearly 100,000,000 of Chinese livestock on hand livestock produces a large amount of ight soil and directly is discharged in the external environment under the situation that does not obtain to deal carefully with, and causes environmental pollution.The method of handling stalk and ight soil at present mainly contains compost and produces biogas.But there are limitation in present compost and biogas production Fang Fang.
One, straw degradative is slow
The slow timely processing that has influenced in biogas fermentation and the biological compost a large amount of stalks that stalk decomposes.The principal element that the restriction stalk decomposes is that the Mierocrystalline cellulose in the stalk is difficult to decompose.But the glucose after Mierocrystalline cellulose decomposes can provide energy for the microorganism in the fermenting process.Therefore in the biogas raw material, add the efficient (Zhang Quanguo " biogas technology and application thereof ", Chemical Industry Press) that cellulase improves biogas production.Based on same reason, add the process that cellulase also can be accelerated the straw biological compost, mention the adding acidic cellulase as patent 160810304360.5 " a kind of method of making fertilizer " and can accelerate composting process.But because the cellulase that aforesaid method is mentioned all needs outsourcing, and cost is higher, though therefore this method effect is better, is not suitable for extensive popularizing and uses.
Two, the production instability of biogas
Studies show that the production of biogas is the biochemical reaction of a complexity, it produces needs to carry out complicated acting in conjunction through multiple microorganism.The temperature in biogas when reaction and the microbe population that is of value to biogas fermentation have determined the output and the stability of biogas production.As utility model patent 161016185590.7 " circulating biogas generator " promptly by unite the heat that utilizes sun power to produce keep the optimum temperuture of biogas fermentation and will ferment after the natural pond slag beneficial microorganism quantity that adds biogas reaction increase biogas fermentation once more realize the stable high yield of biogas.The generation of biogas exists aerobic and two fermenting processs of anaerobism.By the aerobic microbiological fermentation larger molecular organics is decomposed into the environment that small organic molecule is created a strictly anaerobic simultaneously, methanobacteria could utilize small organic molecule to synthesize biogas in the environment of this strictly anaerobic.Therefore,, but still have limitation though simply the method that the natural pond slag is reclaimed to improve methane fermentating microorganism quantity can increase biogas output to a certain extent, and shorten the first aerogenesis of biogas aspect the time effect little.
Three, there is secondary pollution in natural pond liquid
Still residual a large amount of organism that does not decompose fully as yet in the natural pond liquid after the fermentation, the unprocessed direct discharging of these natural pond liquid can cause second environmental pollution.The method of handling natural pond liquid at present mainly is by setting up the redox pool, earlier natural pond liquid is drained into the redox pool, treating to be discharged in the outside atmosphere after liquid interior organism in natural pond fully decomposes again.This method need be the bigger redox pool of floor space of biogas facility auxiliary construction, can't use in the nervous area of land resources.Also there is invention that natural pond liquid is used to make fertilizer in addition, cultivates the substratum of edible mushrooms etc.As: it all is to be converted into utilizable useful product after utilizing natural pond liquid to process that 200710014827.8 1 kinds of patent of invention 200710123079.7 high-efficiency residue in biogas digester and patents of invention are utilized the method for natural pond liquid cultivating drumstick mushroom.The limitation of this method is, still has the unwanted bacteria of some amount in the liquid of natural pond, can have influence on the quality of made substratum.Simultaneously, this method also can't be handled a large amount of natural pond liquid, and being not suitable for environment protection and waste treatment is the project use of target.
Summary of the invention
One of the purpose of this utility model is in order comprehensively to address the above problem, a kind of little ecologic reactor that is used for marsh gas purifying to be provided.
Know-why of the present utility model
A kind of little ecologic reactor that is used for marsh gas purifying provided by the utility model, it is when carrying out marsh gas purifying, promptly by selected several microorganism combinations that are of value to biogas fermentation, inorganic substance after utilizing these microorganisms with remaining organic substance in the liquid of natural pond and decomposition, reduce BOD content and the interior carbonic acid gas of biogas and other content of harmful gas in the liquid of natural pond simultaneously, thereby realize the purification of biogas.

Bacillus subtilisACCC11060;
Principle of the present invention is summarized as follows:
Spirulina is under photosynthesis, and absorbing carbon dioxide discharges oxygen, satisfies the used several microorganism oxygen consumption growth needs of the present invention.
Aspergillus niger and sporangiocyst actinomycetes under the environment of aerobic and suitable temperature, the multiple cellulase of the justacrine of growing.The Mierocrystalline cellulose of these cellulases in can pyrolysis straw produces glucose.These glucose are absorbed synthetic yeast albumen by yeast, and Yeast protein is the required important nutrient of microorganism growth.The Yeast protein that forms after glucose after Mierocrystalline cellulose decomposes and the yeast death has satisfied genus bacillus, aspergillus niger, the required nutrition of actinomycetes growth.
Yeast saccharomyces cerevisiae, bacillus megaterium, bacillus cereus, subtilis etc. can utilize the glucose of generation and the remaining organic substance of natural pond liquid to grow.And under the environment of aerobic, the organic substance in the liquid of natural pond being decomposed into inorganic nutrient salt, these inorganic nutrient salts can provide the basic nutrition material for spirulina carries out the photosynthesis absorbing carbon dioxide again conversely.
Carry under the effect at biogas gas, inside reactor liquid constantly flows, and microorganisms such as spirulina and yeast are taken in the stalk packing material, in the lump it is taken out of when the stalk filter material that more renews.Because spirulina has very high protein content, can improve the carbon-nitrogen ratio in the straw compost process effectively.A large amount of microorganisms of absorption help accelerating organic decomposition course in the biogas fermentation aerobic processes on it simultaneously.
