Description
Technical field
The present invention relates to a kind of biological bacteria liquid pulping method, particularly relate to a kind of biological bacteria and biological bacteria liquid pulping method thereof.
Background technology
Pulping technique is exactly by materials such as the stalk of plant, branch, trunks, is removed the materials such as xylogen wherein and pectin, obtain the process of fibrous matter by degraded (or dissociating).Fiber is the main component of papermaking.
In pulping process, fiber be isolated, first will these non-fibrous material strippings, obtaining fiber is exactly slurrying purpose.
According to the present situation of the current slurrying industry of China, be applied in production and mainly occupy an leading position with chemical pulp, the waste liquor contamination sublimity that chemical pulp produces in producing, damage to land, polluted air; In slurrying, add a large amount of sodium hydroxide (caustic soda), also use chemical noxious element in bleaching process, producing waste liquid cannot all recycle.And it is high to consume energy, power consumption and water consumption large; All using a large amount of electricity in whole production process, causing and becoming power consumption rich and influential family.Waste liquid blowdown flow rate is large; The waste liquid that cannot recycle can only outwards discharge.Do not meet national energy-saving and reduce discharging policy.Material can not reach Efficient Cycle recycling.Chemicals cannot be separated from waste liquid, and organism and chemicals mix, and organism also cannot be reused, and causes a large amount of loss.
Therefore, be necessary exploitation bio-pulping technology, fundamentally solve a pollution difficult problem for pulping and papermaking industry.Bio-pulping technology is adopted although also have in prior art, but the biological bacteria usually adopted is whiterot fungi or actinomycetes, although it makes moderate progress relative to traditional chemical pulping technology, but still there is long reaction time, obtained fiber fineness is low, yield is low defect, be difficult to be applied to actual production.Therefore, still need the biological bacteria that exploitation is new further, improve bio-pulping process, to overcome above-mentioned defect, and realize energy-saving and emission-reduction, water-saving simultaneously, reduce production cost and the rate of utilization of raising material.
Summary of the invention
The object of the invention is to overcome the chemical pulping method of prior art and the above-mentioned defect of bio-pulping method, a kind of new slurrying biological bacteria is provided.Contriver, by long screening operation, obtains the biological bacteria that can realize foregoing invention object being suitable for bio-pulping.
Particularly, biological bacteria provided by the invention is Wickerhamomycesanomalus, and its preserving number is CGMCCNo.5975.
This Wickerhamomycesanomalus bacterium in malt juice liquid medium 25 DEG C cultivate three days, cell is spherical, avette, sausage shape, and size be (4.8-14.4) × (3.6-7.2) μm, have precipitation formation.25 DEG C, wort agar inclined-plane is cultivated one month, bacterium colony cheese shape, oyster white, and surface smoothing is not reflective, edge root shape.Corn Meal Agar Dalmau slat chain conveyor, produces pseudohypha.
Described biological bacteria (Wickerhamomycesanomalus) can be used in the slurrying of biological bacteria liquid.
The present invention also provides a kind of biological bacteria liquid pulping method, and it mainly comprises step:
1) configuration of bacterium liquid: above-mentioned biological bacteria (Wickerhamomycesanomalus) mixed with water, forms bacterium liquid;
2) Feedstock treating: by segment or section after woody raw material peeling, or herbaceous material is cut into chunks, the raw material cut is put into fermentation vat swollen;
3) slurrying, it comprises step:
Discongest: by the raw material thread rolling of swollen and/or crowded stone roller;
Biological degradation: by the raw material soaking after discongesting in the bacterium liquid configured;
Wet sterilization: to be pulled out from bacterium liquid by the raw material after above-mentioned biological degradation, draining, passes into water vapor sterilizing;
Corase grind slurry: the raw material after sterilizing is carried out one section of corase grind slurry, become fibrous bundle;
Fine grinding is starched: above-mentioned one section of corase grind slurry is carried out two sections of fine grinding slurries, makes fibrous bundle be dispersed into single fiber;
Addition in pulp: screen, be filtered through one section of corase grind slurry and two sections of fine grindings slurry after slurry in fibrous bundle, defibrination makes it make single fiber again;
Disappear latent, pulp washing: in warm water, soak, above-mentioned obtained paper pulp for cardboard processed.
Wherein, the density of the bacterium liquid formed in step 1) is more than 6,000 ten thousand/ml bacterium.
Wherein, step 2) in, the woody raw material length cut is 3-4cm, and the herbaceous material length cut is 4-5cm.The described swollen time is 10-12h.
Wherein, the biological degradation temperature described in step 3) remains on 35-40 DEG C, time 34-36 hour.The mass ratio of the raw material after discongesting and bacterium liquid is 1:6-8.Described steam sterilizing is water at atmospheric pressure steam sterilizing 10-30 minute.
Further, step 2) in soak the soak solution after raw material through flocculation, precipitation, supernatant liquor recycling, the fermentation of throw out input methane-generating pit produces biogas.
The advantage of biological bacteria liquid pulping method provided by the invention is: 1) free from environmental pollution: waste liquid directly changes into organic fertilizer, reaches zero release, no pollution.2) bio-pulping can play a protective role to fiber, and compared with traditional chemical process, Whole fiber and half fiber can all reclaim by present method, therefore improve slurry yield.Energy consumption 30% is reduced than traditional slurrying; Paper pulp yield improves 20-25%.3) bio-pulping carries out lignin degradation at ambient pressure, energy-conservation, reduce discharging, low-carbon (LC).4) production cost is low, high financial profit.The cardboard adopting this biological bacteria liquid pulping method to prepare reaches the above level of AA level.Byproduct of the present invention is transported to settling tank flocculation, precipitation, and supernatant liquor returns second stage employ, remakes presoak and uses.Containing nutrient for plants such as gas chromatography and N, P, K such as abundant xylogen in throw out, throw out mixes, acidifying with old bacterium liquid (raw material thickness bacterium liquid of repeatedly degrading, also containing N, P, K, Fe and trace element) again, then together enter in marsh gas fermentation pool, produce biogas.By the Boiler Ash mixing granulation of natural pond slag, natural pond liquid and pulverizing, make granular organic fertilizer, finally dispatch from the factory, realize zero release.
The biological bacteria that the present invention obtains through creating work for a long time by providing above-mentioned contriver, perfect further existing bio-pulping technology, reduce the reaction times, improve purity and the yield of obtained fiber, this technology can be applied on a large scale in actual production.Applying biological bacterium of the present invention at short notice in degrading plant body xylogen produce paper pulp, papermaking, byproduct twice transformation becomes biogas, biogas coal supply, gas boiler for dual purpose combustion heating, saves coal consumption.Finally, natural pond slag makes organic fertilizer, defines the economic circulation new model of " material organic transformation ", reaches no waste discharge, namely zero release.Fundamentally solve a pollution difficult problem for pulping and papermaking industry.Energy-saving and emission-reduction, water-saving, reduces production cost, improves the rate of utilization of material.
For above and other objects of the present invention, feature and advantage can be become apparent, preferred embodiment cited below particularly, and coordinate accompanying drawing, be described in detail below.
