▎ 摘  要

NOVELTY - The utility model claims a graphene production waste water treatment system, comprising a pre-processing unit, a filter unit and an evaporation crystallization unit, the pre-processing unit, a filter unit and an evaporation crystallization unit are orderly connected; through the pre-treatment tank into the sulphuric acid by using sulphate, using fine sand filter and a cartridge filter to remove part of the graphene oxide, using counter to carry out reverse osmosis process shrinks the waste water, produced water is recycled; the concentrated waste water for segmentation and evaporating, crystallizing and separating to obtain industrial grade sodium sulphate and manganese sulphate. greatly reduces steam consumption needed by the evaporation concentration crystallization and segmented evaporation-crystallization process steam can be recycled through reverse osmosis concentrated water, to ensure the purpose of zero discharge and the graphene of the graphene production waste water highly effectively recycling waste water produced.
