Problems solved by technology

However, the waste liquid produced in the production of chemical methods pollutes the environment, destroys the land, pollutes the air, and has high energy consumption, power consumption and water consumption.
It does not comply with the national energy saving and emission reduction policy, and the materials cannot be effectively recycled. The organic matter in the waste liquid is mixed with chemicals, and the organic matter cannot be reused, causing a lot of losses.
Important equipment relies on imports, and the investment cost and maintenance cost of vulnerable parts are high
However, there is incomplete degradation of lignin, serious pollution, and the amount of wastewater produced is 18-19 m 3 Per ton of pulp, the COD of wastewater is 1300-1500

Embodiment 1

[0023] Depend on figure 1 Shown, the inventive method comprises the following steps in concrete implementation:

[0024] (1) Compounding of bacterial liquid;

[0025] A plurality of bacterial species are configured into a complex bacterial flora aqueous solution according to the following mass ratio, which is the bacterial liquid; the ratio of each bacterial species is: brown rot fungus: Acinetobacter ruckeri: Pseudomonas fluorescens: Wickerhamomyces anomalus is ( 1~2):(1~3):(1-3):(2~3);

[0026] (2), washing swelling and steaming wood chips or herbal raw materials;

[0027] The wood chips or herbal raw materials are washed and swelled and then enter the steaming chamber, where they are softened for 10-20 minutes. After the wood chips or herbal raw materials are softened, they enter the oblique spiral dehydrator for dehydration;

[0028] (3), biodegradation;

[0029] Transport the decomposed raw materials to the configured composite bacteria liquid tank, so that the compou...

Embodiment 2

[0049] In the specific implementation of the present invention, the composite bacterial solution is composed of brown rot fungi, Acinetobacter ruckeri, Pseudomonas fluorescens and Wickerhamomyces anomalus in a mass ratio (1.2-1.8): (1.5-2.5): (1.5~2.5): (2.2~2.8) compounded together, add water to make the colony density 6×10 7 more than one / mL composite bacteria solution;

[0050] The chemical liquid is calculated by weight percentage: KOH 2.5-3.5%, H 2 o 2 3-5%, Na 2 SiO 3 1.8-3.5%, DTPA (diethyltriaminepentaacetic acid) 0.2-0.4%, and the balance made of water.

Embodiment 3

[0052] In the specific implementation of the present invention, the composite bacteria solution is composed of brown rot fungus, Acinetobacter ruckeri, Pseudomonas fluorescens and Wickerhamomyces anomalus in a mass ratio of 1.5: 2: 2: 2.5, adding water The bacterial colony density was made to be 6×10 7 more than one / mL composite bacteria solution;

[0053] The chemical liquid is calculated by weight percentage: KOH 3.0%, H 2 o 2 4.0%, Na 2 SiO 3 3.0%, DTPA (diethyltriaminepentaacetic acid) 0.3%, and the balance made of water.

[0054] The field test of the product of the present invention shows that the degree of polymerization of the cellulose is 400 to 600 cp; the apparent specific volume of the cellulose is 6 to 8 cm 3 / g; the average particle size of cellulose is 150~200μm, compared with the prior art, the present invention is owing to adopting biological pretreatment to raw material, makes it further soften, thereby significantly improves the extrusion tearing effe...

Abstract

The invention relates to a method for producing cellulose for an additive through biological ultrasonic waves. The purposes of saving energy, reducing emission, saving water, reducing the production cost and increasing the use rate of matter can be effectively achieved. The method includes the steps that brown-rot fungi, acinetobacter lwoffii, pseudomonas fluorescens and Wickerhamomyces anomalus are compounded, water is added, and compound bacterium liquid with the flora density being 6*107 / mL or above is prepared; a fiber raw material is cut and made to be 3 cm to 5 cm in length, water is firstly used for swelling, then steam defibering is conducted, and water removing is conducted; the fiber raw material obtained after steam defibering is put into the compound bacterium liquid to be degraded and is fished out and subjected to draining, steam sterilization is conducted, the fiber raw material is put into chemical liquid to be defibered into a fiber bundle, the fiber bundle is subjected to ultrasonic treatment to form single fibers, and the single fibers are soaked in warm water and are dried and sterilized; and the fibers are ground into the cellulose. The method is advanced, scientific and easy to operate, the problem of pollution of the cellulose prepared biologically is fundamentally solved, energy is saved, emission is reduced, water is saved, the production cost is reduced, the use rate of matter can be increased, and economic and social benefits are huge.

Description

technical field [0001] The invention relates to cellulose, in particular to a method for bioultrasonic production of cellulose for additives. Background technique [0002] Cellulose is a polysaccharide compound and is the most valuable natural renewable resource for human beings. Cellulose chemistry and industry began many years ago, and it was the main research object during the birth and development of polymer chemistry. The main physiological function of cellulose is to absorb a large amount of water, increase the amount of feces, promote intestinal peristalsis, accelerate the excretion of feces, and make carcinogens The residence time in the intestinal tract is shortened, and the adverse stimulation to the intestinal tract is reduced, thereby preventing the occurrence of intestinal cancer. In the prior art, the preparation of cellulose is mostly through chemical methods, and the waste liquid generated in the production of chemical methods pollutes the environment, destr...
