Abstract
The invention relates to a clean pulping technology of bamboo materials, and especially a clean pulping technology employing biological composite strains. The technology provided by the invention is characterized in that: a composite strain liquid is cultured, and the composite strain liquid is used for pulping. With the technology, a problem of common pulping technologies, that the discharge amount of pollutants is large, is solved. The technology has advantages of energy consumption reducing, water consumption reducing, environment friendly, energy saving, and highly efficient. According to the invention, with the cooperation of various strains, effect and efficiency of bamboo cellulose separation and purification can be effectively improved, and produced wastewater can be processed through harmless treatment.
Description
Technical field
The present invention is a kind of bamboo wood clean pulping process, especially a kind of technology of utilizing the biological compound fungi kind to carry out cleaning pulping.
Background technology
The main component of pulping raw material is cellulose, hemicellulose and lignin, also has materials such as in various degree pectic substance, pigment in addition.Wherein cellulose and hemicellulose are the basis that slurrying need keep, and other composition all belongs to the material that must remove.How environmental protection and energy saving ground separates the purification cellulose and hemicellulose is the difficult problem of pulping process and the key link of research of technique.
Traditional pulp and paper making method is a method of utilizing chemical method, mechanical means or both combinations, and string is separated from raw material, is processed into the production process of true qualities or bleached pulp.There is following problem in this traditional papermaking:
1, seriously polluted, black liquor of pulp making COD, BOD height, wastewater flow rate is big, and the thio-alcohol foul odour is arranged, and can't directly utilize and discharge because of it contains a large amount of harmful chemical industry soda acid compositions, but it is big to implement the pollution control difficulty to it, and cost is high;
2, pulping process energy consumption and water consumption is high;
3, tensile strength, pop strength and the tearing strength to paper pulp all has bigger broken ring effect.
Along with development of biology, people's using microbe has carried out broad research to non-wood-fiber resource pulping process.Research shows; Microorganism with non-cellulose physical capacity in the degradation of fibers raw material extensively is present in nature; Be main with sickle-like bacteria, rhizopus, aspergillus and some basidiomycetes in the fungi, bacterium has bacillus amyloliquefaciens, Ke's formula bacillus, Irving's formula bacillus etc.But up to now, utilize the non-cellulose material in the microbial degradation bamboo fiber raw material, promptly really reach the research report of bio-pulping realistic scale, do not see that almost domestic and international other unit or individual delivered relevant report.
The hemicellulose in the employing biotechnology degradation of fibers raw material and the method for lignin are the development trends of pulp and paper industry.Biological degradation method not only can be guaranteed fiber product and quality, and can reduce production costs, alleviate environmental pollution.
Summary of the invention
The objective of the invention is to solve the existing in prior technology weak point, provide a kind of with complex microorganism bacterial classification and environmental protection and energy saving, technology is simple, with low cost and can improve the bio-pulping process of pulp property.
To achieve these goals, the present invention has adopted following technical scheme: a kind of bamboo wood clean pulping process.Its technology is: a, bamboo is cut into sheet, the dipping back is carried out the thread rolling differentiation with screw extruder to bamboo chip; B, cultivation composite bacteria liquid; C, bamboo material ferment in composite bacteria liquid; D, isolate the bamboo material in the bacterium liquid, and high-temperature sterilization; E, defibrination or making beating obtain paper grade (stock) magma.
Raw material is a bamboo among the said step a, and dipping 4～8h makes the bamboo wood profit rise by compression ratio 1: 4.
Bio-pulping is used the composite bacteria microorganism among the said step b, and bacterium and fungi microbe are composited according to a certain ratio.Microorganism is the composite bacteria of brown rot fungus, whiterot fungi, mushroom tack bacterium composition, about 30 ℃ of cultivation temperature.
Liquor ratio is 1: 5～6 among the said step c, and bacterial concentration is 5～60,000/ml, and fermentation time is 2～3 days.
Cooking of high-temperature steam gas 30min in the said steps d makes the cellulose suction bulk, and to bacteria inactivation rate.
Coarse fiber bundle among the said step e after the deactivation slaking is bulk through wash, discongest, high consistency refining or the making beating after obtain papermaking magma.

The specific embodiment
Bamboo is cut into sheet, behind hot vapour gas steaming 30min, under 1: 4 compression ratio condition, bamboo chip is carried out the thread rolling differentiation with screw extruder; After having cultivated composite bacteria liquid under 30 ℃ of temperature; The bamboo material was fermented in composite bacteria liquid 2～3 days; In bacterium liquid, isolate the bamboo material, and high-temperature sterilization; Defibrination or making beating obtain paper grade (stock) magma.Technology of the present invention and traditional handicraft handsheet paper physical property are as shown in table 1.
