| titleOfInvention | Dye wastewater treatment method |
| abstract | The invention discloses a dye wastewater treatment method, and relates to wastewater treatment. The method comprises the following steps of: pretreating the surface of an industrial titanium plate, preparing a solution containing fluorine ions, using the industrial titanium plate as a positive electrode and common metal as a counter electrode, oxidizing the positive electrode to obtain a TiO2 nanotube array film with an orderly structure and controllable size on the surface of the titanium, and performing heat treatment on the TiO2 nanotube array film to obtain an anatase TiO2 nanotube array film; putting the anatase TiO2 nanotube array film into a reactor filled with wastewater, adding a Fe2+ solution and a H2O2 solution, regulating the pH of the solution to be 2-5, and performing photocatalytic degradation of the wastewater by taking a high pressure mercury lamp as a light source under the condition of introducing oxygen; and taking a TiO2 nanotube array out, and performing ultrasonic cleaning with water for recycle. The photocatalytic treatment efficiency of the TiO2 nanotube array on the wastewater is improved; and the consumption of a Fenton reagent is reduced, the cost is reduced and the treatment efficiency is improved; and a photocatalyst has the characteristics of high stability and capacity of being repeatedly used. |
