Problems solved by technology

[0003] At present, in the papermaking process, the waste liquid produced by the cooked plant fiber will carry a large amount of nutrients and has strong alkalinity. If it is discharged directly, it will cause environmental pollution and waste of resources. After purification, it will increase production. cost, therefore, those skilled in the art have proposed a kind of method that carries out paper pulp and feed coproduction with plant fiber as raw material, to solve the problem raised in above-mentioned background

Abstract

The invention belongs to the technical field of preparation methods for joint production of paper pulp and fodder, and particularly relates to a method for joint production of paper pulp and fodder bytaking plant fiber as a raw material. The method comprises the following steps: cleaning dust and impurities on the surface of the plant fiber with clear water, then putting a portion of the plant fiber into a container for high-temperature cooking for 5-10min, fishing out the plant fiber and removing water by filtration, and putting the cleaned plant fiber into a thread rolling machine to obtaina filamentous product. Waste liquid generated when the paper pulp is manufactured by the plant fiber is turned into wealth;straw is treated with the papermaking waste liquid to serve as coarse fodder, ammonia is not used or less ammonia is used, and thus chemical fertilizer can be greatly saved, the problem that ammoniated straw competes for the chemical fertilizer with farmland is solved, and the organic matter digestibility of straw treated with the papermaking waste liquid can be improved by 20%, the manufacturing utilization rate of the plant fiber is improved, energy is saved, the environment is protected, and the production efficiency is high; and complex microbial florae are added into the waste liquid, so that the fermentation time can be remarkably shortened, fermentation can begenerally completed within 3-5 days, and the fermentation is more sufficient and thorough.

Description

technical field [0001] The invention belongs to the technical field of the preparation method of the joint production of pulp and feed, and in particular relates to a method for the joint production of pulp and feed by using plant fiber as a raw material. Background technique [0002] Plant fiber is a thick-walled tissue widely distributed in seed plants. The paper industry is an industry that manufactures various types of paper products. The paper industry is an important industry closely related to the development of the national economy. It involves forestry, agriculture, machinery Manufacturing, chemical industry, electrical automation, transportation, environmental protection and other industries. At the same time, the paper industry is a technology-intensive, complex process, large resource consumption, and a lot of pollutants. The product range of the industry includes pulp, machine-made paper and cardboard, processed paper, handmade paper, etc. The traditional pulpi...
