The polyvinylidene fluoride (PVDF) microfiltration membrane was modified by vacuum filtration method with cerium oxide-titanium dioxide (CeO2-TiO2), graphene oxide-cerium dioxide (GO-CeO2), graphene oxide-titanium dioxide (GO-TiO2) and graphene oxide/titanium dioxide-cerium oxide[GO/(CeO2-TiO2)], respectively, to prepare composite membranes. The structure and light absorptivity of the composite membranes were investigated by X-ray diffraction, ultraviolet visible diffuse reflection, scanning electron microscopy and Fourier transform infrared spectroscopy. The removal efficiencies of ammonia nitrogen and DOC by composite membranes under dark and ultraviolet light conditions were studied by using the lake water samples from GehuLake branch in Changzhou as raw water. Under dark condition, (GO-CeO2) composite membrane had the highest removal efficiency of ammonia nitrogen (28.21%) and GO/(CeO2-TiO2) composite membrane had the highest removal efficiency of DOC (29.58%). Under ultraviolet light condition, the synergistic effect ofGO, CeO2 and TiO2 resulted in the best removal effect of ammonia nitrogen (65.4%) and DOC (54.7%) byGO/(CeO2-TiO2) composite membrane.
