Abstract

The invention provides a papermaking wastewater environment-friendly treatment system and treatment method, relates to the technical field of papermaking wastewater treatment, and solves the technical problems of material waste and low wastewater treatment efficiency caused by poor recovery effect in current papermaking wastewater treatment. The papermaking wastewater environment-friendly treatment system comprises a physicochemical pretreatment tank (1), a coagulation reaction tank (3), a primary sedimentation tank (4), an adjusting tank (7), a cooling tower (8), a pre-acidification tank (9), an anaerobic reactor (11), an aerobic aeration tank (13), a secondary sedimentation tank (15) and an air floatation tank (16). According to the papermaking wastewater environment-friendly treatment system and treatment method, resources in the papermaking wastewater can be recycled, the cost is saved, the treatment effect of the papermaking wastewater is improved, and the influence of waste residues and waste gas on the environment in wastewater treatment is reduced.

Description

technical field [0001] The invention relates to the technical field of papermaking wastewater treatment, in particular to an environmental protection treatment system and treatment method for papermaking wastewater. Background technique [0002] In wet papermaking factories, a large amount of water is used and discharged from pulping to papermaking. The discharged water is called papermaking wastewater. Except for a part of papermaking white water participating in recycling, the excess wastewater needs to be treated to reach sewage discharge Standards can be discharged, so every pulp and paper mill has a sewage treatment workshop or sewage treatment plant. [0003] However, most of the current sewage treatment systems are not perfect, and the renewable resources in the wastewater are not recovered as much as possible, resulting in a certain waste. In the process of treatment, due to the unreasonable system, the energy consumption of wastewater treatment is high, and the ente...
