▎ 摘  要

NOVELTY - Silt-loaded photocatalyst has silt loaded with graphene-nano bismuth ferrite, which is used to degrading organic pollutant in river and lake. The silt loaded with graphene-nano bismuth ferrite (BiFeO3) is prepared by screening the size of the sediment through cyclone classification, removing the coarse particle to obtain the fine-grained sediment, performing surface activation treatment on fine-grained sediment, supporting graphene on the fine-grained sediment after surface activation and loading the graphene on the sediment for nano-photocatalytic loading. USE - Silt-loaded photocatalyst used for degrading and purifying of organic matter in natural water body. ADVANTAGE - The silt-loaded photocatalyst has good degradation ability for the hard-to-degrade organic pollutant in water and bottom sludge, and can be used for the degradation and purification of organic matter in natural water body, and it has great practical application prospect and commercial development value, and the catalyst solves the problems of catalyst condensation and secondary pollution, and opens up a new way for organic pollution in river and lake.
