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

[0029] The configuration of embodiment 1 bacterial liquid

[0030] The biological bacteria adopted in the present invention have been preserved on April 6, 2012 in the General Microorganism Center (CGMCC, No. 1, Beichen West Road, Chaoyang District, Beijing) at the General Microorganism Center of China Microbiological Culture Collection Management Committee, and its preservation number is CGMCC Rheinheimera tangshanensis No.5972.

[0031] Mix the above-mentioned biological bacteria with water to form a bacterial liquid, the density of the formed bacterial liquid is more than 60 million bacteria / ml, and set aside.

Embodiment 2

[0032] Example 2 Pulping of woody raw materials with biological bacteria liquid

[0033] 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.

[0034] For details, please refer to figure 1 , The flow process of the pulping method with biological bacteria liquid is divided into three stages: the preparation stage, the pulping section and the by-product section.

[0035] (1) Preparation stage: 1-4

[0036] 1)-2): Separate the harvested caragana from the bark. Air separator or other mechanical separation can be used. After the bark is separated, the bark is sent to the organic feed workshop for processing feed, and the bark after peeling is sent to the next program.

[0037] 3) Cut the rod into sections on a cutting machine, the length is 3-4cm, and ...

Embodiment 3

[0056] Embodiment 3 The biological bacteria liquid pulping of herbal raw materials

[0057] 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.

[0058] For details, please refer to figure 2 , The flow process of the pulping method with biological bacteria liquid is divided into three stages: the preparation stage, the pulping section and the by-product section.

[0059] (1) Preparation stage: 1, 4

[0060] Cut the wheat straw into 4-5cm sections, put them into the soaking chamber or soaking tank for washing and cold soaking, first wash away the soil and other sundries on the surface of the raw materials, and soak at the same time, the water temperature is natural temperature, and the time is based on soaking and swelling Subject to,...

Abstract

The invention relates to rheinheimera tangshanensis and a biological bacteria liquid pulping method of the rheinheimera tangshanensis. The rheinheimera tangshanensis is stored with a number of CGMCC No. 5972. The biological bacteria liquid pulping method mainly comprises the following steps of: preparing bacteria liquid; processing raw materials; and pulping, wherein pulping steps comprise the following steps of: defibering, biologically degrading, sterilizing through steam, carrying out rough pulping, carrying out fine pulping, screening a sizing agent, removing latency, and washing the sizing agent. A paperboard prepared by the biological bacteria liquid pulping method provided by the invention reaches a level over AA grade; waste liquid produced in a pulping process can be recycled or transformed into methane which can be served as an energy resource or organic fertilizer, and therefore, energy resources are saved, and environment protection is achieved.

Description

technical field [0001] The invention relates to a pulping method of biological bacteria liquid, in particular to a pulping method of Rhinemeria tangshanensis and its biological bacteria liquid. Background technique [0002] Pulping technology is the process of removing lignin and pectin and other substances from plant straws, branches, trunks and other materials through degradation (or dissociation) 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 produced in chemical pulp production pollutes the environment, destroys the land, and pollutes the air; a large amount of sodium hydroxide (caustic soda) is added to pulping ), chemical harmful elements are also used in th...
