▎ 摘　　要

NOVELTY - Degradation of chemical oxygen demand comprises adjusting pH value of wastewater to 3.0-7.0 with acid or alkali, adding photocatalyst titanium dioxide-graphene oxide-multi-wall carbon nanotube three-dimensional composite material at ratio of 300 mL:1 g, and irradiating with UV light for 1.5 hours at 80 degrees C. USE - The method is used for degrading chemical oxygen demand. ADVANTAGE - The method provides more photo-generated electron transport channels, and improves efficiency of photocatalytic degradation of chemical oxygen demand.
