The invention discloses a processing device for removing phenol and naphthalene in sewage and a method thereof and belongs to the technical field of treatment of chemical wastewater containing poisonous and harmful phenol and naphthalene. The device comprises a processing device body and also comprises a suction pump. A water inlet area, a photo-catalytic oxidation area, a biodegradation area and a membrane mandatory separation area are arranged from one side to the other side in the processing device body. The top of the photo-catalytic oxidation area also comprises an ultraviolet lamp and a TiO2 catalysis plate. An elastic stereoscopic filler is arranged inside the biodegradation area, and the bottom of the biodegradation area comprises an air diffuser. According to the processing method, phenyl ring or polycyclic structure in phenol and naphthalene are opened by photo-catalytic oxidation to be changed into low-molecular substances, and the low-molecular substances are converted into carbon dioxide or other
