1. A UV/O3/H2O2 advanced oxidation reactor, comprising a water inlet pipe, a water outlet pipe, an ultraviolet reactor and an H2O2 adding device, wherein the water inlet pipe is connected to a water inlet in a lower portion of the ultraviolet reactor, the water outlet pipe is connected to a water outlet in an upper portion of the ultraviolet reactor, and the H2O2 adding device is arranged on a connecting pipe of the water inlet pipe; an O3 adding device is arranged on the connecting pipe of the water inlet pipe; the O3 adding device comprises a gas source, an ozone generator and a water injector; the H2O2 adding device comprises a H2O2 storage tank, a metering pump and a static mixer; the H2O2 adding device is disposed to add H2O2 with a certain concentration to pressurized raw water, the water injector is disposed to add ozone with a certain concentration generated by the ozone generator to the raw water which enters the ultraviolet reactor; and the ultraviolet reactor is configured as a structure that has a bottom end provided with an inlet and a top end provided with an outlet, and that has a plurality of ultraviolet lamps embedded therein, and the ultraviolet lamps are arranged at an angle with respect to a plurality of partition plates,
wherein the ultraviolet reactor comprises an ultraviolet reactor cavity and the ultraviolet lamps, each of the ultraviolet lamps consists of a plurality of ultraviolet lamp tubes which are installed at an angle of 15°-30°, and a distance between the ultraviolet lamp tubes is a reciprocal of a difference between a light transmittance of pure water and a light transmittance of a water sample; a length-width-height ratio of the ultraviolet reactor cavity is 3:2:1, 45° baffle plates are arranged at inner corners of the ultraviolet reactor cavity, and the baffle plates arranged at the opposite corners of the cavity are parallel to the ultraviolet lamp tubes; and the partition plates used for fixing the ultraviolet lamp tubes are arranged in the cavity.
