The processing technology specifically comprises the following steps: 1) preprocessing paper pulp fibers; 2) introducing ethylene diamine to the surfaces of silicon dioxide nano particles to obtain preprocessed silicon dioxide nano particles; 3) carrying out an interlayer spacing expansion treatment on nano montmorillonite to obtain pretreated nano-montmorillonite; 4) preparing a paper pulp fiber treatment solution; and 5) diluting the preprocessed paper pulp fibers, adding the diluted paper pulp fibers into the paper pulp fiber treatment solution, performing high-speed stirring, performing grouting and suction filtration, and performing a squeezing-drying treatment to obtain paper pulp fibers meeting requirements. The processing technology can reduce the loss of fine fibers in the dehydration processof paper pulp, the loss rate of fibers is reduced, the technical defects that in the prior art, the fine fibers are dispersed unevenly in the paper pulp and the surface roughness of the paper pulp fibers is increased can be overcome, and produced paper is high in quality and excellent in physical and chemical performance.
