Method for treatment of breeding waste antibiotics based on TiO2 photocatalysis

The invention relates to a method for treatment of antibiotics, in particular to a method for treatment of breeding waste antibiotics based on TiO2 photocatalysis. The method comprises the following steps: using TiO2 as a catalyst in ultraviolet exposure environment, and putting the TiO2 into a mixed solution of the breeding waste antibiotics and water; putting the mixed solution to be under a tritium lamp to perform ultraviolet light irradiation, and ensuring that hole h+ and electron e- are generated on the surface of TiO2 solid, the hole h+ enables H2O to be oxidized, the electron e- enables O2 in the air to be reduced, a .OH group is produced, and the .OH group oxidizes the antibiotics to produce CO2; ensuring that a CO2 is produced when one carbon atom is degraded, and repeating the cycle till the antibiotics are completely transformed into CO2. The method can provide a novel antibiotic degradation method which is mild in reaction conditions, low in energy consumption, capable ofeffective killing pathoge
