▎ 摘　　要

NOVELTY - Graphene photocatalytic net comprises a bottom plate (1), a cover plate (2), a graphene photocatalytic net body (3) and a clamping assembly (4). The top of the bottom plate is provided with a multiple first threaded holes (11). The graphene photocatalytic net body is laid on the top of the bottom plate, and a multiple rings (31) are fixed on the side of the graphene photocatalytic net body. The cover plate is covered on the top of the bottom plate, and the top of the cover plate is provided with a multiple second threaded holes (21). The first threaded rod (22) is rotatably connected in the second threaded hole. The first threaded rod is threadedly matched with the inner side wall of the first threaded hole. The clamping assembly is arranged at the bottom of the cover plate. The clamping assembly comprises a round rod (41), a sleeve (42) and a pressing mechanism (43). The round rod is fixed on the top of the bottom plate. USE - Graphene photocatalytic net used in optical catalysis graphene sewage treatment device (claimed). ADVANTAGE - The organic matter in the sewage is catalyzed and degraded by using sunlight as an irradiation light source combined with the graphene photocatalytic net body, so that the treatment effect of the sewage is more efficient. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an optical catalysis graphene sewage treatment device, which comprises: a base (5), a filter box (6), a photocatalytic treatment box (7) and a water pump (8), the filter box is fixed on the top of the base, a water inlet (61) is fixedly connected to the top of the filter box a filter screen (62) is fixed on the inner side wall of the filter box, a backing plate (71) is fixed on the inner side wall of the photocatalytic treatment box, and a placement groove (711) is arranged on the top of the backing plate, the placing groove is provided with the graphene photocatalytic net, the water pump s fixed on the top of the photocatalytic treatment box, the input end of the water pump is fixedly connected with a water inlet pipe (81), and the output end is fixedly connected with a water outlet pipe (82), the water inlet pipe is fixed on the side wall of the filter box, and communicates with the inside of the filter box, and the water outlet pipe is fixed on the top of the photocatalytic treatment box, and communicates with the interior of the photocatalytic treatment box.
