▎ 摘　　要

NOVELTY - An antipollution three-dimensional electrocatalytic filler comprises polyvinylidene fluoride, butanedione, N,N-dimethylacetamide, graphene, graphite powder, and carbon-based catalyst. USE - Antipollution three-dimensional electrocatalytic filler used for decomposing polycyclic aromatic hydrocarbon in wastewater. ADVANTAGE - The antipollution three-dimensional electrocatalytic filler enables processing of wastewater without blocking the device, improves the processing efficiency of the device, and provides processed wastewater with reduced pollutants. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the filler, which involves stir-mixing N,N-dimethylacetamide, graphite powder, and graphene for 3 hours, adding polyvinylidene fluoride, stirring continuously for 10 hours at 70 degrees C, slowly adding butanedione, stirring continuously for 10 hours, adding the carbon-based catalyst, soaking, stirring continuously for 10 hours, heating to 80 degrees C, filtering, and drying the filter residue at 80 degrees C for 5 hours.
