Embodiment 1

[0025] Take 100 tons of wheat straw and chop it; take 100 tons of water to moisten the chopped wheat straw; inoculate 9 tons of common thermophilic actinomycetes into the wheat straw pile, and use the heat released by common thermophilic actinomycetes during fermentation to make The forage is heated up, and when the temperature is raised to 70°C, the temperature is controlled and fermented for 15 days; after the straw pulp is produced, the deep processing is continued according to the conventional technology.

Embodiment 2

[0027] Take 100 tons of rice straw and chop it up; take 130 tons of water to moisten the chopped rice straw; inoculate 6 tons of brown heat-linked mold into the straw pile, and use the heat released by the brown heat-linked mold to increase the humidity of the forage. When the temperature is raised to 80°C, the temperature is controlled and fermented for 14 days; after the straw pulp is produced, the deep processing is continued according to the conventional technology.

Embodiment 3

[0029] Take 100 tons of the mixture of wood chips and wood powder; take 150 tons of water to moisten the wood; inoculate 7 tons of the mixture of Thermosporium actinomyces, Pyrobacillus and Pyrosporium to the wood pile Inside, the heat released by the strains during fermentation is used to heat up the wood, and when the temperature is raised to 75°C, the temperature is controlled and fermented for 15 days; after the wood pulp is produced, the deep processing is continued according to conventional techniques.

Abstract

The pulp-making process by using microbial fermentation process is mainly aimed at solving the problem of black liquor polluting environment, and incldues the following steps: cutting wheat (rice) straw or wood material, moistening cut wheat (rice) straw or wood material, inoculating the moistened cut wheat (rice) straw or wood material with bacteria or actino mycetes, fermenting and heating, continuously fermenting and zymolysis so as to obtain straw (wood) pulp.

Description

technical field [0001] The technical field to which the invention belongs is the papermaking field, especially the technical field of papermaking using microbial fermentation method. Background technique [0002] The common papermaking technology used in various paper mills is to heat and pressurize the wheat (rice) straw raw material, caustic soda, and cooking agent in a steaming ball, and after a certain period of time, the lignin in the wheat (rice) straw raw material , polysaccharide, pectin, protein and other complex components are dissolved in caustic soda, so that they are separated from cellulose to obtain pulp fiber. The biggest shortcoming of this method is that the black liquor produced is difficult to manage or the management cost is very high. The black liquor is discharged into the river, causing serious pollution to the river water source. At present, reports of papermaking sewage polluting downstream water sources in the Yellow River and ...
