The present invention discloses a papermaking wastewater and sludge ecological recycling system and an ecological recycling method, and belongs to the ecological processing field. The papermaking wastewater and sludge ecological recycling system includes a wastewater pre-treatment station and a reed wetland, the wastewater pre-treatment station comprises a regulation tank, a primary sedimentation tank, a UASB tank, an aerobic tank, a secondary sedimentation tank and a sludge tank, the regulation tank, the primary sedimentation tank, the UASB tank, the aerobic tank, the secondary sedimentation tank and the sludge tank are in turn connected, the secondary sedimentation tank is respectively connected with the regulation tank and the reed wetland, the reed wetland includes a reed sludge bed, an ecological pond, a surface flow wetland and a horizontal flow wetland, the secondary sedimentation tank and the sludge tank both are connected with the ecological pond, the ecological pond, the surface flow wetland and the horizontal flow wetland are in turn connected, and wastewater pre-treatment station sludge distribution pipes are evenly distributed on the reed sludge bed. The papermaking wastewater and sludge ecological recycling system reduces wastewater and sludge treatment and discharge construction and operating cost, improves energy source use ratio, saves water resources, and can realize the sustainable development of papermaking industry.
