A UV-oxidation/disinfection system (100) uses an electrodeless microwave-excited lamp (40) combined with a coaxial flow-through reactor in which liquid to be treated is pumped from the bottom of the reactor (10) and flows upward (12) through a vessel against gravity. A hydrogen peroxide solution is injected into the liquid and mixed by an inline mixer (27) just before the liquid enters the vessel. The solution is irradiated during its entire passage through the vessel by the lamp which has a substantial part of its spectral output in the wavelength most effectively absorbed by hydrogen peroxide molecules. A method of using the coaxial flow-through reactor to destroy toxic chemicals in water is also provided. The reactor is also used for UV disinfection of water supplies. According to another embodiment, two or three reactors are arranged serially such that the output of the first reactor is the input of the second reactor.
