[0035] In practical application, the present invention utilizes a delivery pump of existing technology to input the antibiotic-contaminated water to be treated into the composite catalytic tank 11 through the composite catalytic input pipe 101. The antibiotic-contaminated water undergoes a combined oxidation process of ozone catalytic oxidation and ultraviolet photocatalytic oxidation within the composite catalytic tank 11. Antibiotic-contaminated water flows from bottom to top in composite catalytic tank 11. Ozone microbubbles are introduced into the antibiotic-contaminated water using ozone aeration device 15. Ozone catalytic oxidation of antibiotic-contaminated water is carried out by ozone to destroy the main molecular structure of antibiotics. Using a gas delivery pump based on existing technology, ozone in the ozone storage tank is delivered through pipelines to each main gas delivery pipe 153. The ozone in the main gas delivery pipe 153 is then delivered through gas delivery hoses 1530 to each aeration delivery pipe 152. Finally, the ozone in the aeration delivery pipe 152 is sprayed out from multiple ozone aeration nozzles 1520 into the antibiotic-contaminated water body. The ozone forms dense microbubbles in the antibiotic-contaminated water body. These ozone microbubbles flow from bottom to top in the antibiotic-contaminated water body and come into full contact with the antibiotic-contaminated water body. During ozone aeration, the main gas supply pipe 153 is raised and lowered. The main gas supply pipe 153, through the gas supply hose 1530, can drive each aeration delivery pipe 152 to rotate around the delivery pipe support shaft 1540, adjusting the inclination angle of each aeration delivery pipe 152. Simply put, this adjusts the degree of expansion of each aeration delivery pipe 152 relative to the aeration support pipe shell 151. When the axis of the aeration delivery pipe 152 is perpendicular to the axis of the aeration support pipe shell 151, the degree of expansion of the aeration delivery pipe 152 relative to the aeration support pipe shell 151 is the largest. As the end of the aeration delivery pipe 152 away from the main gas supply pipe 153 gradually droops closer to the aeration support pipe shell 151, the degree of expansion of the aeration delivery pipe 152 relative to the aeration support pipe shell 151 is smaller, thereby adjusting the aeration range of ozone microbubbles in the vertical direction. The extension or retraction of the inner rod of the aeration adjustment drive rod 157 can drive the aeration adjustment sliding cylinder 156 together with the main air supply pipe 153 to move up and down, thereby adjusting the height of the main air supply pipe 153. The multiple ultraviolet light beads 14 in the first accommodating groove 131 are turned on, and under the irradiation of ultraviolet light, the high-activity titanium dioxide nanotube array coating loaded on the outer surface of the photocatalyst loading column 130 will excite to generate electron-hole pairs, which will further catalyze ozone and dissolved oxygen in water to generate a large amount of ·OH, so as to perform ultraviolet photocatalytic oxidation on the antibiotic-polluted water body and destroy the main molecular structure of the antibiotic; According to the parameters of the actual antibiotic-polluted water body, when stronger ultraviolet light is needed, the lamp bead connecting plate 133 is driven to extend from the radial sliding groove 132, and the multiple ultraviolet light beads 14 in the second accommodating groove 134 are turned on to irradiate the antibiotic-polluted water body with more ultraviolet light beads 14; The lamp bead connecting plate 133 is driven to extend from the radial sliding groove 132 by the outward extension driving mechanism 31, and the outward extension driving slider 313 is driven to move along the outward extension support sliding rail 312 by the existing technology of a servo motor through gear and rack transmission, and the outward extension driving slider 313 moves towards the opening of the radial sliding groove 132 to drive the lamp bead connecting plate 133 to extend from the radial sliding groove 132; When weaker ultraviolet light is needed, the lamp bead connecting plate 133 is reversely driven to retract into the radial sliding groove 132, the inner rod of the photocatalytic lifting driving rod 161 retracts to drive the photocatalytic support column 13 to move upwards, so that the photocatalytic support column 13 retracts into the lifting support cylinder 16, at the same time, the inner rod of the auxiliary lifting driving rod 172 extends to drive the photocatalytic auxiliary support column 17 to move downwards, so that the photocatalytic auxiliary support column 17 extends from the auxiliary connecting hole 170, at this time, the photocatalytic auxiliary support column 17 is immersed in the antibiotic-polluted water body, and the multiple ultraviolet light beads 14 in the third accommodating groove 171 are turned on, so that only the multiple ultraviolet light beads 14 on the photocatalytic auxiliary support column 17 are used to irradiate the antibiotic-polluted water body; The tank top cover 12 is provided with a waste gas exhaust pipe which is in communication with the inside of the tank top cover 12, and the used ozone is discharged through the waste gas exhaust pipe and can be harmlessly treated by using the existing technology of a waste gas treatment device; The antibiotic-polluted water body treated by the composite oxidation of ozone catalytic oxidation and ultraviolet photocatalytic oxidation is discharged through the conveying communication pipe 102 and enters the collection input shell 221, and the three-dimensional electrochemical catalytic mechanism 20 is used to perform three-dimensional electrochemical catalytic oxidation on the antibiotic-polluted water body, so as to deeply mineralize the intermediate products generated by the composite oxidation treatment and treat more difficult-to-degrade organic matter; The antibiotic-polluted water body entering the collection input shell 221 flows into the multiple catalytic flow-through pipes 23 from bottom to top and finally flows into the collection output shell 222, and each catalytic input short pipe 2302 is provided with a catalytic input control valve 2303, so that each catalytic input short pipe 2302 can be independently controlled to be opened or closed, according to actual needs, the number of the catalytic input short pipes 2302 at the lower end of each catalytic flow-through pipe 23 can be controlled to be opened, so as to adjust the water inflow and flow rate of the catalytic flow-through channel 230. Each catalytic input short pipe 2302 at the lower end of each catalytic flow pipe 23 can also be opened or closed synchronously, thereby controlling the number of working catalytic flow pipes 23; The antibiotic-polluted water in the collection input shell 221 enters the catalytic flow channel 230 through the catalytic input short pipe 2302 and flows from bottom to top. The catalytic anode 241 and the catalytic cathode 242 are electrically connected to the anode and the cathode of the prior art direct current power supply, respectively. The three-dimensional electrode filler 240 is composed of activated carbon particles loaded with a layer of RuO2-TiO2 titanium-based coating. The three-dimensional electrode filler 240 particles become tiny “bipolar electrodes” under the action of an electric field. These tiny “bipolar electrodes” are used to oxidize the antibiotic-polluted water, greatly increasing the reaction area and mass transfer efficiency; Dry air is input into the aeration stirring delivery pipe 25 using a gas delivery pump of the prior art. The dry air is sprayed from multiple aeration stirring nozzles 251 to form air micro-bubbles in the antibiotic-polluted water and flow from bottom to top. This plays a stirring role on the antibiotic-polluted water, making the three-dimensional electrode filler 240 in a fluidized state and preventing the three-dimensional electrode filler 240 from hardening; The antibiotic-polluted water after three-dimensional electrochemical catalytic oxidation flows into the collection output shell 222 through the catalytic output hole 2301. The water in the collection output shell 222 is finally discharged from the three-dimensional catalytic output pipe 201.
