Abstract

The invention discloses a papermaking pulping technology, and aims at providing a pollution-free odorless energy-saving environment-friendly three-in-one pulping process capable of pulping at normal temperature. The papermaking pulping technology comprises the following steps: deodorizing with ozone water, disinfecting, cleaning, slicing; immersing with an ozone water chemical drug liquid; biological catalyzing and degrading; mechanical fibrillation pulping; bleaching with saturated ozone water; concentrating, pulp squeezing and packing. Classified household garbage is taken as the raw material, and the production cost is reduced. During the whole production flow, no pollution, no foul smell and no suspension are generated, pulping is operated at normal temperature, zero discharge of water is achieved, and the water is reused in a totally-enclosed way, and therefore the papermaking pulping technology is a cleaning environment-friendly pulping technology, conventional chemical pulping technologies do not have the above advantages, and the papermaking pulping technology is high in paper pulp 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...
