Method for preparing virgin pulp for papermaking by utilizing organic enzyme to carry out enzyme treatment on herbaceous plants

The invention discloses a method for preparing virgin pulp for papermaking by utilizing an organic enzyme to carry out enzyme treatment on herbaceous plants, which comprises the following steps: using the herbaceous plants as the raw materials; spraying the organic enzyme on the materials; carrying out grinding by a high concentration hydraulic grinder; stirring and rolling over the ground virgin pulp in a pulp pool to obtain soft crude fibers; and after filtering the soft crude fibers by an inclined screen, feeding the obtained product into an intermediate concentration hydraulic grinder to grind to obtain the virgin pulp for papermaking, which has the beating degree of 27 to 30 degrees. The invention provides a papermaking process, which implements the digestion-free process of preparing the pulp by the herbaceous plants and has no emission capable of polluting the environment; the yield of the pulp is higher than 20 percent than that of the pulp prepared by a conventional grinding process; and the beating
