Aiming at the problem that polymer wastewater is difficult to be treated, the photocatalytic degradation of polyacrylamide (PAM) in water is studied by using TiO2 as catalyst. The results show that light source and catalyst are the necessary conditions for the oxidation of PAM. The energy distribution of light source and the intensity of light have a significant influence on the reaction rate and the degradation effect of wastewater, and it is feasible to treat polyacrylamide wastewater by photocatalytic oxidation.
