▎ 摘  要

NOVELTY - Degrading antibiotic pollutant in wastewater by heterogeneous electrocatalytic flocculation to activate persulfate comprises adding persulfate and magnetic graphene-based Fen+ particles to wastewater to be treated, performing electrocatalytic oxidation and flocculation treatment on wastewater to be treated through electroflocculation reaction device, precipitating iron(II) ion at anode under action of current, rapidly activating persulfate to produce sulfate under synergistic action of magnetic graphene-based Fen+ microelectrode, oxidizing pollutants by sulfate and hydroxide to complete degradation of organic matter, removing incompletely degraded organic matter by adsorption and co-precipitation of highly active flocculation groups formed by iron(III) ion and hydroxide, reacting, allowing to stand, magnetically separating and recycling particle microelectrode material, where anode of electrocoagulation reaction device is an iron pole plate or an iron-containing pole plate. USE - The method is useful for degrading antibiotic pollutant in wastewater by heterogeneous electrocatalytic flocculation to activate persulfate. ADVANTAGE - The method: efficiently and quickly degrades antibiotic pollutants in wastewater; utilizes persulfate having stable chemical properties, and with convenient transportation and storage; and reuses the microelectrode.
