Problems solved by technology

Although the biopulping technology is also used in the prior art, the commonly used biological bacteria are white rot fungi or actinomycetes. Although they have been improved compared to the traditional chemical pulping technology, they still have long reaction time and produce Due to the defects of low fiber purity and low yield, it is difficult to apply to actual production

Embodiment 1

[0030] Example 1 Configuration of bacterial liquid

[0031] The biological bacteria used in the present invention have been deposited in the General Microbiology Center of China Microbial Culture Collection Management Committee (CGMCC, No. 3, No. 1, Beichen West Road, Chaoyang District, Beijing) on ​​April 6, 2012, and its deposit number is CGMCC No. 5975 biological bacteria (Wickerhamomyces anomalus).

[0032] The above-mentioned biological bacteria are mixed with water to form a bacterial liquid, and the density of the formed bacterial liquid is 60 million bacteria / ml or more for use.

Embodiment 2

[0033] Example 2 Biological bacterial liquid pulping of woody raw materials

[0034] Using Caragana korshinskii as the raw material, the biological bacteria liquid pulping method when using woody raw materials is specified. The biological pulping method of other woody materials, such as poplar and eucalyptus, can refer to this process.

[0035] Please refer to figure 1 , The process of biological bacterial liquid pulping method is divided into three stages: preparation stage, pulping section and by-product section.

[0036] (1) Preparation stage: 1-4

[0037] 1)-2): Separate the harvested Caragana. It can be separated by a winnowing machine or other mechanical separation. After the skin rods are separated, the skins are input into the organic feed workshop for processing feed, and the peeled rods are input to the next program.

[0038] 3) Cut the rod into sections on the cutting machine, the length is 3-4cm, and the oblique opening is better to increase the penetration area.

[0039] ...

Embodiment 3

[0057] Example 3 Biological bacterial liquid pulping of herbal raw materials

[0058] Using wheat straw as the raw material, the biological bacteria liquid pulping method when using herbal raw materials is specified. The biological pulping method of other herbal raw materials, such as wheat straw, rice straw, and corn stover, can be carried out with reference to this process.

[0059] Please refer to figure 2 , The process of biological bacterial liquid pulping method is divided into three stages: preparation stage, pulping section and by-product section.

[0060] (1) Preparation stage: 1, 4

[0061] Cut the wheat straw into 4-5cm sections, and enter the soaking bin or soaking tank for washing and cold soaking. First, wash away the dirt and other debris on the surface of the raw material and soak at the same time. The water temperature is natural temperature and the time is soaked and swelled. Whichever is 10-12h. After the turbidity of the liquid after multiple soaking, the super...

Abstract

The invention relates to bio-bacteria and a bio-bacterial solution pulping method. The bio-bacteria are wickerhamomyces anomalus with a collection number of CGMCC No.5975. The bio-bacterial solution pulping method mainly comprises the following steps of: preparing a bacterial solution; processing raw materials; and pulping, namely defibering, biodegradation, steam sterilization, coarse grinding, finely grinding, pulp screening, latency, and pulp washing. The paperboards made by the bio-bacterial solution pulping method reach AA or above level; and the waste liquid produced in pulp making can be recycled or changed into methane which is a kind of energy or organic fertilizers, so energy can be saved and environment pollution is avoided.

Description

Technical field [0001] The invention relates to a biological bacteria liquid pulping method, in particular to a biological bacteria and a biological bacterial liquid pulping method. Background technique [0002] Pulping technology is the process of degrading (or dissociating) plant stalks, branches, tree trunks and other materials to remove lignin and pectin and other materials to obtain fibrous materials. Fiber is the main component of papermaking. [0003] In the pulping process, to separate out the fibers, these non-fibrous substances must be dissolved out first, and obtaining fibers is the purpose of pulping. [0004] According to the current status of China’s pulping industry, chemical pulp is the mainstay used in production. The waste liquid generated in chemical pulp production pollutes the environment, destroys the land, and pollutes the air; a large amount of sodium hydroxide (caustic soda) is added to the pulping industry. ), chemical harmful elements are also used in the...
