Example Embodiment

[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: Bacillus sp. with CGMCC No.5971, Acinetobacter lwoffii with CGMCC No.5973, Pseudomonas fluorescens with CGMCC No.5974, deposited Wickerhamomyces anomalus, CGMCC No. 5975.

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

[0034] Bacillus: Acinetobacter ruckeri: Pseudomonas fluorescens: Wickerhamomyces anomalus is 1-3:1-2:1-2:2-3; the density of the formed bacterial solution is 6×10 7 More than bacteria / ml, spare.

Example Embodiment

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

[0036] 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.

Abstract

The present invention relates to a composite flora and an application of the composite flora in a biological bacterial liquid pulping process. The composite flora comprises bacillus sp. with a preservation number of CGMCC No.5971, acinetobacter lwoffii with a preservation number of CGMCC No.5973, pseudomonas fluorescens with a preservation number of CGMCC No.5974, and Wickerhamomyces anomalus with a preservation number of CGMCC No.5975. 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 pulping method of biological bacterial liquid, in particular to a composite bacterial group and a pulping method of biological bacterial liquid. 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 the bleachin...
