Abstract
The invention discloses a method utilizing small-molecule diketone to serve as optical active agent for oxidation treatment of dye waste water and belongs to the field of dye waste water treatment. The method comprises the steps: filtering the dye-containing waste water to remove suspended matter; adding a small-molecule diketone compound to the dye-containing water body, and evenly mixing; and placing the dye-containing water body under an ultraviolet source to perform irradiation until dyes are decolorized. The method initially determines the structural characteristics of diketone capable of serving as the dye-decolorizing optical active agent: the molecular configuration is in a chain shape, and molecules are small. The dye-decolorizing method based on diketone is based on a reaction induced by ultraviolet light, can achieve efficient decoloration of various dyes, and has remarkably higher decoloration efficiency than a traditional UV/H2O2 method. Besides, the decoloration efficiency is not subjected to influence of coexistent alcohol in the water body, simultaneously the acid environment is favorable for promoting the reaction, and accordingly the method has more obvious advantages in the acid water body. The method has an autoacceleration performance in degrading the dyes, and the degradation speed is improved along with proceeding of the reaction.
