[0017] Example
[0018] 1) Wheat straw pretreatment→softening→microbial decomposition→slicing→refining→screening→to obtain wheat straw slurry;
[0019] 2) Disintegration of waste paper→purification and impurity removal of slurry→concentration, maturation and medium-concentration refining of slurry→to obtain waste paper slurry;
[0020] 3) Mix the wheat straw pulp and waste paper pulp at a mass ratio of 1:1.5 to obtain a mixed pulp;
[0021] 4) The mixed slurry is then passed through the front pool to stabilize the liquid level and slurry concentration, and then passes through the white bucket, flushing pump, and enters the pressure screen. The fiber bundles and impurities are removed from the pressure screen, and then enters the headbox for cloth The pulp is then dehydrated in the wire section to form a wet paper web, then pressed, pre-dried, sizing, post-dried, and formed into a parent roll in the reeling section, and then rewinded and slit into the required specifications;
