NOVELTY - Renovation of black smelly water comprises (i) preparing reduced graphene modified nano-titanium dioxide heterogeneous structure composite photocatalyst; (ii) adding the homogeneous mixture into fiber slurry to obtain high density polyethylene network; (iii) drying naturally the nano-photocatalytic film-coated high-density polyethylene network in air and drying in drying room temperature; and (iv) setting the modified graphene nano-photocatalytic film-coated high-density polyethylene network on creek, contacting with water and receiving light black and black smelly water. USE - The method is useful for renovation of black smelly water (claimed). ADVANTAGE - The method is simple, saves energy, environment-friendly and economical and does not need aeration. DETAILED DESCRIPTION - Renovation of black smelly water comprises (i) preparing reduced graphene modified nano-titanium dioxide heterogeneous structure composite photocatalyst; (ii) manufacturing water-resistant and impact-resistant aluminum cross-linking agent, preparing homogeneous mixture of the reduced graphene-modified nanometer titanium dioxide heterogeneous structure composite photocatalyst obtained and aluminum-based crosslinking agent, adding the homogeneous mixture into fiber slurry to obtain high density polyethylene network or attaching to high-density polyethylene fiber web and making into nano-photocatalytic film coated high-density polyethylene fiber network; (iii) drying naturally the nano-photocatalytic film-coated high-density polyethylene network in air and drying in drying room temperature; and (iv) setting the modified graphene nano-photocatalytic film-coated high-density polyethylene network on creek, contacting with water and receiving light black and black smelly water.
