Amount has as many as 3,000,000,000 tons, and China's agricultural crop straw annual output is more than 900,000,000 tons.Straw are utilized using biogas fermentation technical treatment
Stalk not only can produce efficient, clean high-grade energy, while the biogas residue and biogas slurry that generate can also be directly used as organic fertilizer
Material, a kind of effective outlet of can yet be regarded as.Biogas fermentation technology itself is a kind of highly developed technology, is turned using the technology
Change stalk is new energy, the quality of life that can alleviate China's conventional energy resource pressure, improve the rural area people；Another party
Face, also solves the problem that the problem of outlet of crop material, reduces because of its open incineration, huddles and the brings such as disorderly set to the unfavorable shadow of environment
It rings.In fact, stalk marsh gas is clearly carried out emphasis as a main renewable energy by China supports development.
It is well known that the wood fibre structure of stalk complexity is to hinder the key factor of its biodegrade, therefore carrying out
Before biogas fermentation, it usually needs pre-processed to stalk.Common preprocess method includes physics pretreatment, the pre- place of chemistry
Reason and Biological Pretreatment, from the point of view of current application, the method mainly combined using physics pretreatment+chemical pretreatment, i.e.,
Chopping/crushing+acid/base pretreatment.However, currently used acid-base pretreatment method is mainly strong acid or pretreatment by strong alkali, example
Such as hydrochloric acid, sulfuric acid, sodium hydroxide, potassium hydroxide, this generally existing equipment etching problem of preprocess method, and needs are largely
Water cleans pretreated raw material or a large amount of soda acid is needed to neutralize.When being cleaned with water, can lose molten
Solution property organic matter, when with acid-base neutralization, and can generate a large amount of sodium ion and chloride ion, it is not only possible to inhibit anaerobic fermentation,
It may also result in environmental pollution, and will affect the later use of biogas residue.And biologic pretreatment method is for cellulose, hemicellulose
Element, the degradation of lignin and not up to good technical effect.

Pretreated liquid portion is subjected to biogas fermentation after liquid immersion stalk；The physical-chemical-of Publication No. CN105255953A
The method of Biological Pretreatment corn stover combines 1% sodium hydroxide and mould processing stalk progress stalk ingredient point using crushing
Analysis；Publication No. CN106119295A's utilizes NH4HCO3To pre-process the method for corn stover and the anaerobic fermentation of corn stover
Method, using NH4HCO3Processing corn stover has simultaneously carried out anaerobic fermentation to stalk after processing.The above invention carries out stalk
Anaerobic fermentation is carried out after pretreatment again, the period of anaerobic fermentation is shortened to a certain extent, improves gas production, but all deposit
More many and diverse operating, due to needing to add bronsted lowry acids and bases bronsted lowry, security risk is high, and can also generate sewage in preprocessing process causes
