Abstract
A mechanical pulping technique with biodegradation to remove lignin includes proper degradable processing of lignin by microbes and mechanical grinding. Its advantages are cyclic use of water, no sewage drainage, biodegradation conducted in stack of raw material, high quality of product and low cost.
Description
The invention belongs to a kind of novel pollution-free paper paper technology that utilizes the biotechnology exploitation.
At present, in paper industry, be chemical method substantially, a large amount of waste water has brought serious pollution problem to environment.Therefore, people have begun mechanical defibrillation papermaking, the research of microbial degradation lignin pulping and paper-making, in nineteen sixties, just there is the people to seek, screen the microorganism of energy xylogen degradation at occurring in nature, by 1987, the bio-pulping Study on Technology is extensively carried out in countries in the world, also there are many scholars in China at present in the research of carrying out this respect, aspect patent, " biological delignification-machinery pulping technology " patent of invention (number of patent application 97101537.6) that has Dalian University of Technology to declare on January 28th, 1997.Up to the present, Shang Weijian have breakthrough, enter the report of suitability for industrialized production scale.
The objective of the invention is to: propose a kind of biodegradation delignification-machinery pulping technology.
Biodegradation delignification-machinery pulping technology of the present invention, comprise that plant material preparation → biodegradation delignification → machinery grinds the technical process of separating slurrying, it is characterized in that: in the biodegradation delignification process, bacterial classification inoculation is to adopt the method for bacterial classification parcel plant material to carry out.Bacterial classification parcel raw material process is the process of raw material absorption bacterial classification, and bacterial classification also enters among the fiber gap and pit of raw material in parcel raw material surface.Its bacterial classification can be made into powdery, and liquid form uses, can adopt dust, modes such as spray, immersion inoculate, to adopt strain liquid (mycelia liquid) immersion way better, the preparation of strain liquid can adopt prior art to carry out.Soak time is different and can be controlled at half an hour to tens hour as required by its raw material.Wrap up by force to select for use, the microorganism a little less than the cellulose degradation ability is advisable the lignin degradation ability with bacterial classification.General is good to select the strain excellent in whiterot fungi, the white rot basidiomycetes for use.Same microorganism has than big difference the lignin degradation ability of different pulping raw materials, should select for use to be suitable for the strong microbial strains of this kind raw material lignin degradation ability according to different pulping raw materials.The controlled condition of the temperature of biodegradation process, humidity, oxygen supply, degradation treatment time length etc. should be determined according to the bacterial strain uses therefor growth characteristics.General biodegradation delignification can be controlled between 3-30 days.Sponge after the biodegradation delignification is handled adopts the mechanical jordaning technology of prior art and refining equipment to carry out the defibrination processing, can obtain desirable bio-mechanical pulp product.
Biodegradation delignification-machinery pulping technology of the present invention has the sterilization treatment of not needing, and is easy to the large-scale industrialization production application, equipment investment is few, and process conditions are easy to control, good product quality, production cost is low, and is pollution-free, and industrial water such as can all recycle at advantage.
Embodiment:
The strain liquid preparation:
Get commercially available white rot basidiomycetes BB-098 bacterial classification, adopt prior art to make mycelia liquid.
The biodegradation delignification, the machinery pulping operation:
200 kilograms of raw material bagasses (unsterilised processing), adding BB-098 mycelia liquid soaked 12 hours, pick up extract to moisture content between 60-100%, place light compacting on the rickyard, under 25 ℃ of-32 ℃ of conditions of natural climate of locality, carry out air and exchange the processing of oxygen supply solid state fermentation biodegradation delignification naturally, after 28 days, adopt 1400 rev/mins single disc refiner pulp grinder to carry out three sections defibrinations processing.Abrasive disk space, I section 1mm, II section 0.5mm, III section 0.1mm, refining concentration w=3%.Obtain the paper pulp about 40 ° of SR of beating degree,, copy into quantitative 60g/m by the national standard sampling
2Page, measuring its pi of strength by national standard, to the results are shown in Table the strength character that 1:(and alkalization learn before the bagasse pulp bleaching suitable)
The manufacture paper with pulp strength character of page of table 1 bagasse biological mechanical pulp
