▎ 摘　　要

NOVELTY - Treating ecological water using graphene photocatalytic network system comprises selecting polluted slow-flowing water body, and salvaging the floating objects on water surface, spreading aquatic plants and bottom net into river, and sinking the aquatic plants and bottom net sink into river bed, assembling graphene photocatalytic net, selecting polyethylene rope, using triangle fixing method for fixing the polyethylene rope to two ends of each group net for connecting cloth net floating frame, arranging an optical fiber irradiating layer, using optical fiber irradiating layer for sizing graphene photocatalytic net, arranging the number of optical fibers in optical fiber illuminating layer, fixing and uniformly distributing illuminating end on irradiated layer of optical fiber, assembling cloth net floating frame, providing water circulation device, setting fixed pile on shore, connecting to cloth net floating frame, and slowly releasing graphene photocatalytic net. USE - The method is useful for comprehensively treating ecological water using graphene photocatalytic network system. ADVANTAGE - The method: is comprehensive; has high aesthetics and good treatment effect by adopting graphene photocatalytic network, good removal effect on pollutants, and has good water ecological treatment effect; combines photocatalysis technology with aquatic plant treatment technology.
