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

[0031] The configuration of embodiment 1 bacterial liquid

[0032] The biological flora used in the present invention has been preserved on April 6, 2012 at the General Microbiology Center (CGMCC, No. 3, No. 1, Beichen West Road, Chaoyang District, Beijing) of the China Microbiological Culture Collection Management Committee, and the preservation number is Bacillus sp. of CGMCC No.5971, Acinetobacter lwoffii of CGMCC No.5973, Pseudomonas fluorescens of CGMCC No.5974.

[0033] The above-mentioned composite bacteria group is configured into a composite bacteria aqueous solution according to the following mass ratio, which is the bacterial solution:

[0034] Bacillus: Acinetobacter ruckeri: Pseudomonas fluorescens: 1-3:1-2:1-2; the density of the formed bacterial liquid is more than 60 million bacteria / ml, for later use.

Embodiment 2

[0035] Example 2 Pulping of woody raw materials with biological bacteria liquid

[0036] Caragana is used as raw material, and the pulping method of biological bacteria liquid when woody raw materials are used is specifically described. The biopulping method of other woody raw materials, such as poplar and eucalyptus, can be carried out with reference to this process. When using caragana, the composite flora is configured according to the following mass ratio: Bacillus: Acinetobacter ruckeri: Pseudomonas fluorescens is 3:2:2; when poplar is used, the composite flora is configured according to the following mass ratio Configuration: Bacillus: Acinetobacter ruckeri: Pseudomonas fluorescens is 3:1:2; when Eucalyptus is used, the composite flora is configured according to the following mass ratio: Bacillus: Acinetobacter ruckeri: Pseudomonas fluorescens Bacteria is 2:1:2.

Embodiment 3

[0059] Embodiment 3 The biological bacteria liquid pulping of herbal raw material

[0060] Using wheat straw as a raw material, the pulping method of biological bacterial liquid when using the herbal raw material is specifically described. The biopulping of other herbal raw materials, such as wheat straw, rice straw, and corn stalks, can be carried out with reference to this process.

[0061] When wheat straw is used, the composite flora is configured according to the following mass ratio: Bacillus: Acinetobacter ruckeri: Pseudomonas fluorescens is 2:1:2; when straw is used, the composite flora is configured according to the following mass ratio Configuration: Bacillus: Acinetobacter ruckeri: Pseudomonas fluorescens is 1:1:2; when corn stalks are used, the composite flora is configured according to the following mass ratio: Bacillus: Acinetobacter ruckeri: Pseudomonas fluorescens The ratio of single cell bacteria is 2:2:1.

Abstract

The invention relates to a compound bacterium used for pulping a biological bacterium fluid and the application of the compound bacterium. The invention further provides a method for pulping the biological bacterium fluid. The compound bacterium comprises bacillus (CGMCC No.5971), acinetobacter lwoffii (CGMCC No.5973) and pseudomonas fluorescens (CGMCC No.5974). The method mainly comprises the steps as follows: preparing the bacterium fluid; handling raw materials; and pulping which comprises defibering, bio-degradation, steam sterilization, rough pulping, fine pulping, pulp screening, latency and pulp washing. Paperboards prepared by the method for pulping the biological bacterium fluid reach or exceed AA levels. Waste liquid generated in the pulping process can be recycled or translated into methane which can be used as energy resources or organic fertilizers. The method has the advantages of energy conservation and environmental protection.

Description

technical field [0001] The invention relates to a pulping method of biological bacterial liquid, in particular to a composite bacterial group for pulping of biological bacterial liquid and its application. Background technique [0002] Pulping technology is the process of degrading (or dissociating) raw materials such as plant straws, branches, and trunks to remove lignin and pectin and other substances to obtain fibrous substances. Fiber is the main component of papermaking. [0003] In the pulping process, to separate the fibers, the non-fibrous substances must be dissolved first, and the fiber is the purpose of pulping. [0004] According to the current situation of China's pulping industry, chemical pulp is mainly used in production, and the waste liquid generated in chemical pulp production pollutes the environment, destroys land, and pollutes the air; a large amount of sodium hydroxide (caustic soda) is added to pulping ), chemical harmful elements are also used in t...
