Method for preparing herbal biological fiber and biological paper pulp

Abstract

The invention discloses a method for preparing a herbal biological fiber and biological paper pulp, and the used microbial composite agent and a preparation method thereof. The biological fiber is prepared through pretreatment of a herbal raw material, biological degumming fermentation, and subsequent mechanical treatment of a fermentation product. The composite agent comprises degumming bacteria, nutrition bacteria and decolorizing bacteria, and various strains are synergistic without antagonistic reaction. In the method for preparing the biological fiber and the biological paper pulp, a chemical additive is not needed at all, but the high-cellulose and hemicellulose biological fiber and the biological paper pulp can be industrially produced; decolorization is complete, and the produced biological fiber and biological paper pulp have white color; a bleaching process is avoided, so investment in decolorizing production equipment is saved, and fiber extracting and pulping investment cost can be effectively reduced; in addition, waste gas and waste water are not generated in the fiber extracting and pulping process, inorganic pollutants are not generated, waste water and waste residues produced in each process step can be produced and converted into a biological fertilizer, and water is recycled.

Description

technical field [0001] The present invention relates to the preparation method of fiber and paper pulp, more specifically relates to a kind of preparation method of herbal biological fiber and biological paper pulp. Background technique [0002] An important problem facing the world's paper industry is environmental pollution. In recent years, China's paper and paperboard production and consumption have increased at a rate of 8-10% per year. In 2009, my country's paper and paperboard production reached 86.4 million tons, and its consumption was 85.69 million tons, an increase of 8.27% over the previous year. and 7.99%. On the one hand, there is a huge demand for paper and paper products. On the other hand, there is an extreme shortage of raw materials for papermaking. Moreover, my country's paper mills generally suffer from serious pollution, which does not comply with the national environmental protection policy. As a result, my country's paper industry is caught in a dilem...

AI Technical Summary

Problems solved by technology

Problems in this method: incomplete degumming, high lignin content of the prepared fiber pulp, long cultivation time of compound bacteria, and heavy odor of this method, which is not suitable for urban application

Problems in this technical solution: because this method is degumming of a single strain, the decomposition of lignin is not complete, and at the same time, raw materials are used for pulping, incomplete degumming, poor color, gray ink color, and insufficient toughness

But it still has the following problems: degumming of a single strain of bacteria, incomplete decomposition of lignin, and long pulping cycle; moreover, the difficulty of screening white rot bacteria is the biggest obstacle to large-scale production

[0009] In summary, the main problems of several biopulping technologies listed above are: single degumming, incomplete decomposition of lignin, long time (generally takes 20-30 days), and no process feasibility; and, due to The decomposition and decolorization are not complete. These technologies inevitably require subsequent chemical methods such as alkaline cooking to completely decompose and bleach the materials, which is far from the industrial production of bio-pulp.

[0010] After consulting a large amount of data, and through repeated comparative experiments and analysis, the inventor found that the main reason why the complex flora is difficult to succeed in the prior art is that the screening and matching of the complex flora are extremely difficult.

Since the complex flora is very easy to produce antagonistic effects, it is very easy to affect the effect of microorganisms on the preparation of biofiber and biopulp
