Abstract
The invention discloses a biogas residue fermentation raw material, which aims to provide a fermentation raw material for biogas, which has the advantages of high gas generation speed, high utilization rate of raw materials and long gas generation period. The biogas residue fermentation raw material comprises the following components in parts by weight: 60-150 parts of livestock and poultry manure, 5-20 parts of effective microorganisms and 1-10 parts of biogas residue. The livestock and poultry manure is composed of the following three components in parts by weight: 20-60 parts of dry chicken manure. 20-60 parts of dry pig manure and 20-60 parts of dry cattle manure. The biogas residue fermentation raw material is especially suitable for a newly built biogas tank.
Description
Technical field
The present invention relates to biogas field, specifically, relate to a kind of natural pond slag fermentation raw material.
Background technology
Biogas be a kind of colourless, have taste, poisonous, have a smelly mixed gas, its composition is not only with the kind of fermentation raw material and relative content is different changes, and each is variant because of fermentation condition and fermentation stage.Generally, the main component of biogas is methane, carbonic acid gas and a small amount of gases such as hydrogen sulfide, carbon monoxide, hydrogen, nitrogen and ammonia.Biogas only just can be obtained biogas of fine quality, that amount is many meeting under microbial growth condition and methane-generating pit normal running (operation) conditions.Now the fermentation raw material of biogas is mainly by peasant household, cultivate livestock and poultry to solve, and raw material ratio is more single and not enough, but the trend cultivating is centralization, mass-producing future development, and the rural area labour that goes out is more in addition, and peasant household's cultivation amount is fewer and feweri.In recent years, country drops into substantial contribution development methane-generating pit for farm household, solve rural energy problem, because cultivation peasant household number is few, fermentation raw material wretched insufficiency, cannot meet the condition of the normal operation of methane-generating pit, many methane-generating pits are idle, even scrap, in addition raw material composition is single, gas production rate is not enough, has affected the development of biogas industry.Therefore, the composite material of marsh gas of research and development scientific formula is the key addressing this problem.
At present, we retrieve the open source literature of some biogas fermentation materials, for example:
1. Chinese Patent Application No. 20091O167968.2, open day on April 21st, 2010, this application case discloses a kind of composite material of marsh gas and preparation method, it comprises and utilizes feces of livestock and poultry, crop waste stalk is through stack retting, dry, pulverization process, add biological bacteria, additive, be uniformly mixed and become product, raw material mixes by following weight part: feces of livestock and poultry 70-80%, agricultural crop straw 15-25%, biological bacteria 3-6%, additive 0.001-1%, by feces of livestock and poultry, agricultural crop straw stack retting, be dried, pulverize, add biological bacteria and additive, mixing is mixed thoroughly, make composite material of marsh gas.Its weak point is: bacterial classification is less, has affected the decomposition rate of biogas, causes aerogenesis speed slower.
2. Chinese Patent Application No. 201310050639.6, and in open day on May 13rd, 2013, this application case discloses a kind of composite material of marsh gas, and its component by quality is: feces of livestock and poultry 70-80kg, bacterium slag 10-15kg, biological bacteria 10kg, natural pond slag 5kg.Said feces of livestock and poultry is dried poultrymanure 30kg, dry pig manure 10-40kg, dry cow dung 10-40kg.The throw out drying that said natural pond slag is methane-generating pit, the product of pulverizing.Its weak point is: bacterial classification is less, has affected the decomposition rate of biogas, causes aerogenesis speed slower.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide the biogas fermentation raw material that a kind of aerogenesis speed is fast, utilization rate of raw materials is high, the aerogenesis cycle is long.
For achieving the above object, the present invention is achieved by the following scheme:
A natural pond slag fermentation raw material, comprises following component, is expressed as: feces of livestock and poultry with parts by weight: 60～150 parts, EM bacterium: 5～20 parts, natural pond slag: 1～10 part.
Wherein feces of livestock and poultry is comprised of three kinds of components, is expressed as: dried poultrymanure with parts by weight: 20～60 parts, dry pig manure: 20～60 parts, dry cow dung: 20～60 parts.
Described EM bacterium is that a kind of mixed bacterium generally comprises 80 kinds of useful mushrooms such as sporeformer, yeast, milk-acid bacteria.
Described methane slag is that residue or the big-and-middle-sized biogas engineering that methane-generating pit for farm household produces after biogas produces the residue drying after biogas, the product after pulverizing.
The principle of work of invention: marsh gas fermentation processes is in fact substance metabolism and the conversion process of energy of microorganism.In catabolic process, biogas microorganism obtains energy and material, and to meet self growth and breeding, most of Substance Transformation is methane and carbon dioxide simultaneously.Various like this organic substances are constantly decomposed, and have just formed the important step of nature matter and energy circulation.Thus, fermentation raw material production biogas is to realize by the biochemical reaction of series of complex.
Compared with prior art, the present invention has following beneficial effect:
1. aerogenesis speed is fast.With respect to prior art, the made fermentation raw material of the present invention contains more beneficial bacteria, has promoted the decomposition rate that organic substance has just started to drop into methane-generating pit, accelerates " hydrolysis " process, is conducive to shorten the speed that aerogenesis had been walked, improved to aerogenesis.
2. utilization rate of raw materials is high.With respect to prior art, the made fermentation raw material of the present invention contains more beneficial bacteria, can make the hydrolysis of organic substance more thorough, has improved raw-material utilization ratio.
3. the aerogenesis cycle is long.The made fermentation raw material of the present invention contains more beneficial bacteria, after organic substance hydrolysis, has formed good biogas environment, and gas deliverability is stronger.
