Abstract

The invention discloses a papermaking pulping process, aiming to provide a three-in-one pulping process that is pollution-free, odorless, room temperature pulping, energy-saving and environment-friendly. The method includes the following steps: deodorization, disinfection, cleaning and slicing with ozone water; immersion in chemical liquid in ozone water; biocatalysis and degradation; mechanical pulping; bleaching with saturated ozone water; concentration, pulping and packaging. The production cost is reduced by using classified domestic garbage as raw materials. The whole production process has no pollution, no odor, no suspended solids, normal temperature pulping, zero discharge of water, and fully closed recycling. It is a clean and environmentally friendly pulping process, which cannot be achieved by chemical pulping methods, and pulp High yield.

Description

technical field [0001] The invention relates to the field of papermaking process, in particular to a pulping process in the papermaking process. Background technique [0002] At present, countries around the world continue to invest huge sums of money in research and development for the treatment and reuse of municipal solid waste. At present, it is not a difficult problem to classify domestic waste, unless there is a problem of high or low classification rate, but no one can completely recycle the classified domestic waste for post-processing. Here it is the key point that the classified treatment of municipal solid waste is difficult to popularize. It is still a practical problem for the post-processing of classified reuse resources, especially for mixed wood fiber species. Most of the current pulping methods are chemical pulping, which is suitable for modern production and has strong adaptability to raw material pulping. , short cycle and large scale, but there are obvi...
