| titleOfInvention | Treatment method of chrome-containing dyeing wastewater |
| abstract | The invention discloses a treatment method of chrome-containing dyeing wastewater, which comprises the following steps: adding a photocatalyst onto wastewater containing hexavalent chrome and dyes, evenly dispersing, regulating the pH value of the wastewater, and irradiating the wastewater with visible light, wherein the photocatalyst is an amorphous titanium dioxide photocatalyst. In the invention, a visible light-catalyst combined photocatalytic redox system is adopted; colored dyes are utilized to absorb visible light; and under the action of the amorphous titanium dioxide (Am-TiO2), the visible light drives the transfer of electrons according to the route dyes--Am-TiO2--Cr (VI), thereby implementing synergic performance of the reduction of highly-toxic Cr (VI) and the degradation of dyes under visible light, and achieving the goal of simultaneously purifying heavy metals and organic pollutants in the chrome-containing wastewater. |
