[0017] The present invention will be further illustrated in combination with the following examples.
[0018] A process for treating waste paper pulp from a paper mill, the steps include:
[0019] 1) The waste paper pulp is sent to the paper-plastic separator through the conveyor belt for grinding and separation. The crushed pulp will flow through the filter screen of the paper-plastic separator and flow into the water collecting tank under the paper-plastic separator. Large long fibers and solid impurities are thrown out from the rear of the paper-plastic separator and fall into the first sedimentation tank.
[0020] 2) Pump the solid-liquid mixture in the water collection tank into the rotary screen filter, filter out the pulp, the pulp enters the papermaking workshop, and the filtrate flows into the circulation tank, and is reused after purification.
[0021] 3) Precipitate the plastic packaging film, long fibers, and solid impurities that fall into the first sedimentation tank. Unrec
