The invention discloses a paper tube raw paper solid waste treatment and recycling process and a process thereof, and mainly relates to the technical field of paper tube raw paper solid waste treatment, and the process comprises the following steps: packaging, pulp washing, crushing, screening, concentrating, purifying and secondary concentrating. According to the method, the slurry residue solid waste is reasonably and effectively recycled, and impurities and slurry generated in all the treatment processes are recycled; the removal rate of papermaking solid waste impurities is as high as 95%, all papermaking solid wastes are reasonably utilized, and the process is green and environment-friendly; and the slurry in the solid waste is effectively recycled, so that the raw material cost is saved to a certain extent. 本发明公开了一种纸管原纸固废处理循环再利用流程及其工艺，主要涉及纸管原纸固废处理技术领域，包括以下步骤：打包、洗浆、碎解、筛选、浓缩、净化、二次浓缩。本发明使浆渣固废得到合理有效的回收处理，且所有处理过程中产生的杂质和浆料均得到了回收利用；使造纸固废杂质去除率高达到95％，所有造纸固废均得到合理利用，绿色环保；有效的回用固废中的浆料，一定程度上节约了原料成本。
