▎ 摘  要

NOVELTY - Method for treating graphene-based wastewater, involves (a) adjusting the pH of wastewater to 5-9, passing the wastewater to graphene suspension sieve under action of gravity, and passing the water in wastewater to water collecting tank arranged below the graphene suspension using graphene suspension sieve under action of gravity, and (b) modifying sprayed graphene microchips on graphene suspension sieve using graphene oxide with poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) triblock copolymer and polyvinylpyrrolidone in order. USE - Method for treating graphene-based wastewater. ADVANTAGE - The method reduces the agglomeration between graphene, increases the adsorption capacity.
