[0002] Papermaking technology is specifically divided into two forms: mechanical and manual. The mechanical process is carried out continuously on a papermaking machine. The pulp suitable for paper quality is diluted with water to a certain concentration, and initially dehydrated on the wire section of the papermaking machine to form wet paper sheets. The sheets are then pressed and dehydrated, and then dried into paper. A large amount of wastewater will be generated during the initial dehydration and pressing dehydration. In order to prevent the wastewater from being discharged into the water body and causing serious pollution to the water environment, and to avoid the waste of water resources, it is necessary to use wastewater recovery and utilization equipment.
