| description | The utility model belongs to the technical field of papermaking wastewater purification treatment. The utility model discloses a papermaking wastewater treatment system, which comprises a collecting well, an inclined screen, a floatation tank, a pollutant filter tank, an anaerobic tank, an aerobic tank, a secondary sedimentation tank and a sludge thickening tank, wherein the collecting well is connected with the inclined screen, the floatation tank, the pollutant filter tank, the anaerobic tank, the aerobic tank and the secondary sedimentation tank in sequence through a pipeline; the pollutant filter tank is provided with a pipeline connected with a papermaking water tank; the anaerobic tank, the aerobic tank and the secondary sedimentation tank are respectively provided with a sludge reflux pipeline connected with the sludge thickening tank. Most of papermaking wastewater purified by the treatment system disclosed by the utility model can be recycled, and little can be directly discharged. Moreover, fine fib |
