NOVELTY - The utility model claims a graphene photo-catalytic net fixing structure for water treatment, comprising a return frame plate, the edge of the upper part of the return frame plate is fixedly connected with a plurality of hemispherical cover distributed equidistantly; the middle position of the inner side wall of the return frame plate is horizontally provided with a splicing edge groove; the splicing edge groove is inserted with a graphene photo-catalytic net; the edge part of the graphene photo-catalytic net is fixedly connected with multiple fixed ring rings distributed in equal distance. The utility model is fixedly connected with a plurality of equidistantly distributed fixing ring rings at the edge part of the graphene photo-catalytic net; the later stage can remove the fixing bolt from the fixing ring ring to replace the graphene photo-catalytic net; the fixing mode is more stable, The invention avoids the problem that the traditional technology uses the bandage to fix the graphene photo-catalysis net which is easy to break.
