▎ 摘　　要

NOVELTY - Light/bioelectrochemical integrated module water purification system device comprises photocatalytic system device and bioelectrochemical processing unit, the photocatalytic system device includes a solar photovoltaic cell (1), the bioelectrochemical processing unit includes at least one group of circuits composed of bioanode (4), composite cathode (6) and additional cathode (5), the composite cathode and the additional cathode are connected in parallel, the bioanode is made of carbon material, the composite cathode is made of carbon material as a base material, and modified by in-situ synthesis of cellulose carbon aerogel, the iron-based oxide is supported by co-precipitation, and graphene, iron oxide or molybdenum disulfide is supported on the additional cathode as a catalyst. USE - The device is useful for in treatment of trace organic pollutants (trace organic pollutants is organic pollutants with benzene ring structure, where organic pollutants with benzene ring structure is pyrene, dichlorobiphenyl or tetrabromobisphenol A) in water (all claimed). ADVANTAGE - The device: can quickly adsorbs trace organic micro-pollutants in water body on composite cathode, realizes the catalytic oxidation and decomposition into small molecules simultaneously under synergistic effect of additional cathode and external light source system, and deeply degrades into carbon dioxide and water by biological anode, and realizes the high-efficiency purification of micro-polluted water. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the light/bioelectrochemical integrated module water purification system device.
