▎ 摘　　要

NOVELTY - Preparation of highly-graphitized biological carbon base material comprises crushing and sieving biological carbon, cleaning and drying, adding cleaned and dried biological carbon into acid solution, stirring, water washing to neutral, drying to obtain acid modified biological carbon, mixing acid modified biological carbon with potassium ferrate, grinding, and performing high-temperature pyrolysis under nitrogen atmosphere. USE - The method is for preparing highly-graphitized biological carbon base material for treatment of waste water containing heavy metal complex (claimed) as particle electrode in three-dimensional particle electrode for deep mineralization of organic ligand. ADVANTAGE - Graphene nanolayer structure can be peeled off to form on surface of biological carbon material for reinforcing electronic transmission performance, endowing rich oxygen-containing functional group and strengthening heavy metal complex cracking ability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for treatment of waste water containing heavy metal complex comprising adding highly-graphitized biological carbon base material to two-dimensional electrode reaction system containing heavy metal complex waste water, uniformly stirring and mixing, applying current, reacting, and performing precipitation separation.
