▎ 摘　　要

NOVELTY - Treating graphene-containing slurry wastewater involves adding alkali liquor into the graphene-containing slurry wastewater, and adjusting the pH value of the graphene-containing slurry wastewater to 7-7.5. The polymerization agent is added under a stirring state and stirred, until particles are formed and uniformly dispersed to obtain a mixed solution. The polymerization agent is polyaluminium chloride. The flocculating agent is added into the mixed liquid, stirred, until the flocculate and the water have a separation trend. The flocculating agent is polyacrylamide. When the floc and water have a tendency to separate, and stopped stirring for sedimentation. The upper layer is a wastewater layer, the lower layer is a graphene-containing layer, and the upper layer and the lower layer are respectively collected. USE - Method for treating graphene-containing slurry wastewater. ADVANTAGE - The method enables to prevent the re-formation of mixtures and difficulties in disposal of wastewater that meets the standard discharged, and graphene sediment collected and disposed of as a general solid waste. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene-containing slurry wastewater treatment device, which comprises a waste water treatment container (2), a waste water collection container (3) and a graphene filter device (4). The waste water treatment container with stirring device (5) is provided with a waste water inlet and a feed inlet at the top. The side opening is connected to the waste water collection container pipeline, The graphene collection container (6) and a waste water collection container are connected to the pipeline below the graphene filter device. DESCRIPTION OF DRAWING(S) - The drawing shows schematic diagram of devices used in the treatment process of wastewater containing graphene slurry.
