Apparatus and method, belong to technical field of biological fermentation.
Background technology
Vinegar grain is using the organic waste discharged during grain raw material production vinegar, in recent years, with country's vinegar processed
Greatly developing for industry, produces the vinegar grain of discharge up to 3,000,000 tons every year, with acid big (acetic acid content 36000mg/kg), slightly
The features such as content of cellulose (25.78% (butt)) high, gross protein value low (12.79% (butt)), difficult decomposition.Above-mentioned spy
Point causes that current vinegar grain processing mode be present, for example, fraction vinegar grain is used as animal feed and edible mushroom is planted
Training material, as feed drying high cost;Culture medium of edible fungus consumption is few, it is impossible to from substantial solve problem;Most of vinegar grain
Go out of use, for a long time, landfill is its main processing mode, and the content of organic matter higher causes to be produced during landfill
A large amount of sour water leakage pollution underground water and edaphic percolate and the greenhouse gas methane of the unordered discharge of generation.Effective place
Reason vinegar grain, reduces the pollution of environment, realizes the recycling of vinegar grain, is the important way for solving vinegar industry discarded object processed in recent years
Footpath.
Anaerobic fermentation is the frontier of domestic and international Recent study, can be generated while degradation of organic substances matter hydrogen,
The biomass energy gas such as methane, is to improve one of environment, effective way of utilization of waste as resource.Vinegar grain spy maximum in itself
Point is that low percentages of protein, crude fiber content be higher, acetic acid content is abundant.Anaerobic digestion includes 4 processes:Extracellular hydrolysis,
Produce acid, produce acetic acid and methane phase, traditional homogenous anaerobic digestion can only process relatively low fermentation raw material concentration (less than 20%), vinegar
The poor slag of grain is not easily decomposed and acetic acid content is abundant, and homogenous anaerobic digestion methane phase process is easily made in a reactor
Crusted into vinegar grain and floated, system is easily acidified, and causes the stability and gas producing efficiency of vinegar grain biogas fermentation relatively low.
Vinegar grain raw material is belonging to organic acid content raw material higher, and whole anaerobic digestion process methane phase process is rate-limiting step
Suddenly, cause vinegar grain and easily produce organic acid to suppress when carrying out single-phase continuous Anaerobic Digestion, lag phase is larger.In order to avoid having
Machine acid suppresses, and traditional homogenous anaerobic digestion can only the low yield operation under relatively low load.Therefore, unrestraint efficient anaerobic is developed
Firedamp gas equipment is produced in digestion and technique turns into the key that the vinegar residue resource of high content organic acid is processed.
The content of the invention
It is a primary object of the present invention to the problem for overcoming prior art to exist, there is provided a kind of vinegar grain solid-liquid split-phase anaerobism disappears
Change the apparatus and method for producing biogas, effectively using the organic acid of vinegar grain abundant raw material can be conducive to vinegar grain methane engineering technology
