NOVELTY - The utility model claims a device for treating polluted water by graphene doped titanium dioxide photo-catalysis, comprising a controller and a storage battery set, the storage battery set is connected with the controller through the cable, the inverter is connected with the lamp shade through the cable, the inner part of the lamp shade is provided with an ultraviolet lamp, the lower part of the ultraviolet lamp is provided with a stainless steel wire net, the back side of the stainless steel wire net is provided with a buoy. The graphene-doped titanium dioxide photo-catalytic treatment device for treating polluted water, by matching between the lampshade and the ultraviolet lamp, using ultraviolet light as light source, generating redox reaction with organic pollutant, realizing water purification, further decomposing and converting other inorganic pollutants, such as CN -, NO2 -, H2S, SO2, NOx and so on, avoids the traditional only using a little part of ultraviolet light in the solar light energy, easy to be affected by the weather and the light catalytic efficiency is not high so as to cause the device utilization rate is not high.
