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, Rheinheimera tangshanensis of CGMCC No.5972, Acinetobacter lwoffii of CGMCC No.5973, and Pseudomonas fluorescens with CGMCC No.5974 and Wickerhamomyces anomalus with CGMCC No.5975.

[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: Rheinmus tangshanensis: Acinetobacter ruckeri: Pseudomonas fluorescens: Wickerhamomyces anomalus is 1-3:1-3:1-2:1-2:2-3; the density of the formed bacterial liquid For more than 60 million bacteria / ml, reserve.

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 caragana is used, the composite flora is configured according to the following mass ratio: Bacillus: Rheinrichia Tangshan: Acinetobacter ruckeri: Pseudomonas fluorescens: Wickerhamomyces anomalus is 3:1:2:2:2 ; When poplar is adopted, the composite flora is configured according to the following mass ratios: Bacillus: Rhinemeria tangshanensis: Acinetobacter ruckerii: Pseudomonas fluorescens: Wickerhamomyces anomalus is 3:2:1:2:2; For eucalyptus, the composite flora is configured according to the following mass ratio: Bacillus: Rheinrichia tangshanense: Acinetobacter ruckeri: Pseudomonas fluorescens: Wickerha...

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: Rheinrichia Tangshan: Acinetobacter ruckeri: Pseudomonas fluorescens: Wickerhamomyces anomalus is 2:2:1:2:3; When rice straw is used, the composite flora is configured according to the following mass ratio: Bacillus: Rheinrichia Tangshan: Acinetobacter ruckerii: Pseudomonas fluorescens: Wickerhamomyces anomalus is 1:3:1:2:3; For corn stalks, the composite flora is configured according to the following mass ratio: Bacillus: Rheinrichia tangshanense: Acinetobacter ruckeri: Pseudomon...

Abstract

The invention relates to biological flora and a biological bacterium liquid pulping method. The composite flora comprises bacillus sp. with the collection number CGMCC No.5971, rheineheimera tangshanensis with the collection umber CGMCC No.5972, acinetobacter lwoffii with the collection number CGMCC No.5973, pseudomonas fluorescens with collection number CGMCC No.5974, and Wickerhamonmyces anomalus with the collection number CGMCC No.5975. The method mainly comprises the following steps of: preparing bacterium-containing liquid; treating raw materials; and pulping, namely defibering, performing biodegradation, performing steam sterilization, coarsely grinding to obtain pulp, finely grinding to obtain pulp, screening pulp materials, performing latency and washing pulp. A paperboard which is prepared by the biological bacterium liquid pulping method can reach above the AA level. Waste liquid produced in the pulping process can be recycled or converted into methane or organic manure which is used as energy resources. Energy resources are saved, and the method is environment-friendly.

Description

technical field [0001] The invention relates to a pulping method of biological bacterial liquid, in particular to a biological bacterial group and a pulping method of biological bacterial liquid using the same. 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...
