| titleOfInvention | Preparation method of compound photocatalytic flocculating agent |
| abstract | The invention discloses a preparation method of a compound photocatalytic flocculating agent. The method comprises the following steps of: firstly, preparing polymeric ferrum and aluminum, concretely, mixing coal ash, pyrite dross and manganese dioxide to form mixed waste residue, adding sulfuric acid into the mixed waste residue, and filtering while stirring, wherein the filtrate is the polymeric ferrum and aluminum solution; then, preparing nano titanium dioxide, concretely, mixing butyl titanate and absolute ethyl alcohol together to obtain a solution A, mixing the absolute ethyl alcohol with distilled water and concentrated nitric acid to obtain a solution B, dropping the solution B into the solution A to obtain a mixed solution, dropping the polymeric ferrum and aluminum solution into the mixed solution, mixing uniformly, drying the mixture to form gel, grinding the gel into powder, and roasting the powder to obtain the nano titanium dioxide; and finally, preparing the compound photocatalytic flocculating agent, concretely, adding the nano titanium dioxide into the polymeric ferrum and aluminum solution, and performing ultrasonic emulsification. The prepared flocculating agent has both flocculation capability and photocatalytic degradation capability, is excellent in effect, low in cost and simple in process. |
