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] Example 1 Configuration of bacterial liquid

[0032] The biological flora used in the present invention has been deposited at the General Microbiology Center of the China Microbial Culture Collection Management Committee (CGMCC, No. 3, No. 1, Beichen West Road, Chaoyang District, Beijing) on ​​April 6, 2012, and it contains the deposit number: Rheinheimera tangshanensis with CGMCC No.5972, Acinetobacter lwoffii with CGMCC No.5973, Pseudomonas fluorescens with CGMCC No.5974 .

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

[0034] Tangshan Rheinoniae: Acinetobacter reuteri: Pseudomonas fluorescens is 1-3:1-2:1-2; the density of the formed bacterial solution is more than 60 million bacteria / ml, and it is reserved.

Embodiment 2

[0035] Example 2 Biological bacterial liquid pulping of woody raw materials

[0036] Using Caragana korshinskii as raw material, the method of pulping with biological bacteria liquid when woody raw material is used is specified. The biological pulping method of other woody raw materials, such as poplar and eucalyptus, can refer to this process. When Caragana korshinskii is used, the composite flora is configured according to the following mass ratio: Rheinella tangshanensis: Acinetobacter rouxii: Pseudomonas fluorescens is 1:2:2; when poplar is used, the composite flora is as follows The mass ratio is configured: Tangshan Rheinoniae: Acinetobacter reuteri: Pseudomonas fluorescens is 2:1:2; when eucalyptus is used, the composite flora is configured according to the following mass ratio: Tangshan Rheinonia: Acinetobacter reuteri: Pseudomonas fluorescens is 2:1:2.

[0037] Please refer to figure 1 , The process of biological bacterial liquid pulping method is divided into three stag...

Embodiment 3

[0059] Example 3 Biological bacterial liquid pulping of herbal raw materials

[0060] 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.

[0061] When wheat straw is used, the composite flora is configured according to the following mass ratio: Rheinonia tangshanensis: Acinetobacter reuteri: Pseudomonas fluorescens is 2:1:2; when straw is used, the composite flora is as follows Quality ratio configuration: Tangshan Rheinoniae: Acinetobacter ruckeri: Pseudomonas fluorescens is 3:1:2; when corn stalks are used, the composite flora is configured according to the following quality ratio: Tangshan Rheinoniae : Acinetobacter reuteri: Pseudomonas fluorescens is 2:2:1.

Abstract

The present invention relates to a composite flora and a pulping method by using a biological bacterial liquid of the composite flora. The composite flora comprises rheinheimera tangshanensis with a preservation number of CGMCC No.5972, acinetobacter lwoffii with a preservation number of CGMCC No.5973, and pseudomonas fluorescens with a preservation number of CGMCC No.5974. The method mainly comprises: preparing a bacterial liquid; treating raw materials; and pulping, wherein pulping comprises: fiber kneading or squeezing rolling, biodegradation, steam sterilization, crude pulp grinding, fine pulp grinding, pulp material screening, soaking, and pulp washing. The paper board prepared by using the pulping method can achieve a level of more than an AA grade. In addition, waste liquid generated during a pulping process can be recycled or converted into biogas or an organic fertilizer adopted as an energy source so as to provide advantages of energy source saving and environment protection.

Description

Technical field [0001] The invention relates to a biological bacterial liquid pulping method, in particular to a composite flora and a biological bacterial liquid pulping method. Background technique [0002] Pulping technology is the process of degrading (or dissociating) plant straws, branches, tree trunks and other raw 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, in order to separate 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 the production of chemical pulp 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 als...
