Abstract: The present invention relates to a reduced graphene oxide-coated filament that inhibits the adsorption of pollutants when applying a filament filter in a wastewater treatment process, thereby enabling a long-term usage of the filament filter by coating the hydrophobic filament with reduced graphene oxide (RGO) and maximizing the hydrophobicity of the filament; and to a manufacturing method thereof. The method for manufacturing a reduced graphene oxide-coated filament according to the present invention comprises the steps of: swelling the hydrophobic filament; coating the swollen filament with graphene oxide (GO) by immersing the swollen filament in a polar aprotic solvent having the graphene oxide (GO) dispersed therein; and reducing the graphene oxide (GO).
