Method for rapidly removing antibiotics in water

The invention belongs to the technical field of water treatment, and particularly relates to a method for rapidly removing antibiotics in wastewater. According to the invention, the variety and concentration of free radicals generated by vacuum ultraviolet (VUV) photolysis are controlled by adjusting the concentration of dissolved oxygen in water, and step-by-step selective removal of various antibiotics in water is realized by relying on the oxidation-reduction action of different free radicals. According to the method provided by the invention, the maternal removal rate and mineralization rate of the antibiotics in the wastewater can respectively reach 98% and 86%. According to the method, no chemical agents, catalysts and other substances are added, accurate step-by-step controllable removal of multiple antibiotics in oxidation reduction is achieved only by adjusting the concentration of oxygen in the system, evolution of bacterial drug resistance is controlled from the source, and the method has the techn
