The invention discloses a treatment method of organic dye in waste water. The method comprises the following steps: (1) soaking a sponge in graphene oxide suspension emulsion to obtain a graphene oxide composite sponge; placing the graphene oxide composite sponge in mixed liquid of a nanoscale photocatalyst and a reducing agent to obtain photocatalyst-modified graphene composite sponge hydrogel; washing and drying the photocatalyst-modified graphene composite sponge hydrogel to obtain a photocatalyst-modified graphene composite sponge; (2) enabling the waste water containing the organic dye topass through an adsorption reactor loaded with the photocatalyst-modified graphene composite sponge to adsorb the organic dye in the waste water; (3) taking out the photocatalyst-modified graphene composite sponge after adsorption and saturation, and performing catalytic decomposition on the organic dye under illumination to obtain a regenerated photocatalyst-modified graphene composite sponge. The method can effectively adsorb the organic dye in the waste water, and an adsorbent material used is easy to regenerate.
