The invention discloses a method for the comprehensive utilization of energy grass in the fields of feeds, biogas and paper pulp, and belongs to the field of biomass resource utilization. For obtaining the highest biomass yield per unit land area, and fully utilizing the energy grass (an economic crop with a huge application potential), according to the method, the applications of the energy grass in the three fields of the feeds, the biogas and the paper pulp are organically combined, and through creative tests and full actual application effect contrasts, a set of effective comprehensive utilization method of the energy grass is developed.

Description

A kind of method that energy grass fully utilizes in feed, biogas and paper pulp field
Technical field
The invention belongs to biomass resource utilization field, relate to the recycling of energy grass, be specifically related to a kind of method that energy grass fully utilizes in feed, biogas and paper pulp field.
Background technology
Current energy grass has relevant application, as in biomass energy, edible and medical fungi is produced, desert treatment, the application in the fields such as animal husbandry, but current existing technology is only confined to the application of energy grass in particular area, in order to adapt to the technological requirement of particular area and obtain better economic worth, often gather when maximum yield of biomass does not reach maximum in the energy grass average production phase, so just do not play the maximum energy production potential of energy grass on unit soil, making full use of this resource of energy grass is not realized yet, and there is the problems such as the discharge of more discarded object in related process.
Current energy grass has relevant application, as in biomass energy, edible and medical fungi is produced, desert treatment, the application in the fields such as animal husbandry, but current existing technology is only confined to the application of energy grass in particular area, in order to adapt to the technological requirement of particular area and obtain better economic worth, often gather when maximum yield of biomass does not reach maximum in the energy grass average production phase, so just do not play the maximum energy production potential of energy grass on unit soil, making full use of this resource of energy grass is not realized yet, and there is the problems such as the discharge of more discarded object in related process.
Summary of the invention
The object of the present invention is to provide a kind of method that energy grass fully utilizes in feed, biogas and paper pulp field.In order to obtain the highest yield of biomass of land area of one unit, and make full use of the huge industrial crops of this application potential of energy grass, the application of energy grass in feed, biogas, paper pulp three fields combines by the present invention, by creationary test and the contrast of sufficient practical application effect, have developed a set of effective energy grass method of comprehensive utilization.
For achieving the above object, the present invention adopts following technical scheme:
A kind of method that energy grass fully utilizes in feed, biogas and paper pulp field comprises the following steps:
(1) from more than ground 5 ~ 20cm, energy grass plant is neatly cut off, then energy grass fresh green leaves and tender stalk part are separated with the old stalk part of energy grass;
(2) energy grass fresh green leaves and tender stalk part are ground into 1 ~ 8cm, are dried to moisture 60 ~ 85%, add feed ensiling agent or the ensiling ensilage of 4 ~ 15 days, mix, airtight storage 15 ~ 60 days; By energy grass fresh green leaves good for ensiling and tender stalk part Direct-fed animal; Or be dried moisture 5 ~ 25%, be crushed to 2 below cm, add Animal nutrition additive, make commercial animal feed;
(3) old for energy grass stalk is crushed to 3 ~ 15 cm, put into closed container, add water, the water surface did not have culm, added the natural pond liquid of the normal fermentation of 0.5 ~ 6%, and airtight acidifying fermentation 2 ~ 6 days under the constant temperature of normal temperature or 30 ~ 60 DEG C, filters and obtain acid solution and fermentation residue;
(4) acid solution imported in marsh-gas fermentation tank and carry out biogas fermentation, fermentation temperature 30 ~ 60 DEG C, pH=6.5 ~ 8.0,5 ~ 35 days moisture retention time, the waste liquid after fermentation is used as the fertilizer of energy grass growth;
(5) fermentation residue use water is rinsed 2 ~ 5 times, be processed into paper pulp.
The processing method of described paper pulp adopts one or more in alkaline process, sulphite process, solvent pulping, the slurrying of dirt thing, Mechanical Method, chemical mechanical pulping, chemical thermomechanical method.
Described energy grass is one or more in Pennisetum plant, Sorghum propinquum, sugar grass, giantreed, reed, class reed, sugarcane, spot thatch, those special grass, sudangrass, Caulis Miscanthis floriduli, reed, awns, awns beanstalk, Dicranopteris amplachinget Chiu, Arundinella hirta (Thunb.) Tanaka, Plantula Neyraudiae Reynaudianae, silage corn, lemongrass, Spartina alterniflora, Value of Spartina Anglica, switchgrass.
Remarkable advantage of the present invention is:
(1) gather when energy grass average production phase endogenous substance output is the highest, the living beings that limited land output is maximum can be made full use of.
(2) the present invention make use of energy grass completely, technique clean and safe, discharges, achieve no pollution, zero-emission without any discarded object.
(3) product of the present invention has animal feed, biogas, paper pulp, all has very high economic development value.
Detailed description of the invention
Set forth the specific embodiment of the present invention further with example below, the present invention includes but be not limited to following instance.
A kind of method that energy grass fully utilizes in feed, biogas and paper pulp field comprises the following steps:
1. kind to plant huge bacterium grass, within the average production phase dry matter production the highest in harvesting, at above 10cm place, face, huge bacterium meadow, huge bacterium grass plant is neatly cut off.Huge bacterium grass fresh green leaves and tender stalk (part that huge bacterium grass top fresh green leaves is concentrated) are cut off with the old stalk portion of huge bacterium grass (huge bacterium grass fresh green leaves and tender stalk part are stalk and aging cured leaf with lower part) contact site, this is in stipes length 6cm again.The defining method of optimal harvest time: time the ratio in different growing stages plant weights/growth period is maximum.
2. fresh green leaves step 1 split with pulverizer and tender stalk part are ground into segment, and length, at 1 ~ 8cm, is dried to moisture 70%, adds feed ensiling agent, mixes, airtight storage 60 days.Huge bacterium grass fresh green leaves good for ensiling and tender stalk part are dried to moisture 15%, are crushed to 2 below cm, add Animal nutrition additive, make commercial animal feed.
3. the huge bacterium culm after step 1 being split is crushed to 3 ~ 15 cm, and the huge bacterium culm crushed puts into closed container, adds water, and the water surface covers culm, adds the normal fermentation natural pond liquid of 1%, airtight acidifying fermentation under the constant temperature of normal temperature or 35 DEG C, fermentation time 6 days.Rear filtration of having fermented obtains acid solution and fermentation residue.
4. acid solution conduit step 3 obtained imports in marsh-gas fermentation tank and carries out biogas fermentation, fermentation temperature 37 DEG C, pH=6.5 ~ 8.0,20 days moisture retention time.Waste liquid after fermentation is used as the fertilizer of huge bacterium grass growth.
