▎ 摘　　要

NOVELTY - Improving wastewater treatment by silica-supported graphene oxide comprises sequentially treating wastewater through pretreatment, biochemical system, and secondary sedimentation tank, treating sewage in secondary sedimentation tank, entering a packed tank filled with silica-loaded graphene oxide for treatment, when the adsorption capacity reaches saturation, removing particulate matter adsorbed on surface of material by water washing, collecting washed particulate matter, discharging it into dirt chamber, removing the heavy metal ions bound by chemical bonds by pickling, regenerating the material by strong alkali and weak acid salt and restoring the performance of material. USE - The method is useful for improving wastewater treatment by silica-supported graphene oxide. ADVANTAGE - The method removes suspended matter and chroma heavy metal ions in sewage, increases strength of synthetic material, is beneficial to expose carboxy group of EDTA, and to capture heavy metal ions in water.
