The invention belongs to the technical field of spinning, particularly relates to a high-strength polyethylene gel spinning system white oil deep purification and cyclic utilization process, and aims to solve the problems of incomplete purification, low cyclic utilization rate, unstable reuse quality, large adsorbent loss and high energy consumption in the prior art, and provides the following scheme: the method comprises the following steps: S1, collecting and pretreating crude white oil; the method comprises the following steps: collecting crude white oil generated in a high-strength polyethylene gel spinning extraction section, centrifugal deoiling and dry tail gas condensation, collecting the crude white oil into a crude white oil storage tank, adding a pretreatment aid into the crude white oil, and realizing deep purification and efficient circulation of the high-strength polyethylene gel spinning waste white oil through cooperation of a five-stage closed-loop process and five sets of customized formulas in a nitrogen protection atmosphere. The adsorption efficiency is improved by more than 35%, the index is close to that of fresh white oil, the cyclic utilization rate of the white oil is more than or equal to 95%, the consumption of each ton of fibers is reduced to below 1kg from 20kg, the hazardous waste output can be greatly reduced by more than 85% by the process, and VOC (volatile organic compounds) can be discharged after reaching the standard.
