Novel multi-technology synergetic catalysis advanced micro-bubble ozone oxidation tower

The invention belongs to a multi-technology synergetic catalysis advanced micro-bubble ozone oxidation tower mainly aiming at the treatment of refractory industrial wastewater. Influent (1) and O3 generated by an ozone generator (24) are injected into a water distribution cabin through a dissolved gas pump (5) and enter a micro-bubble release contact area (7) through a pore plate to release dissolved gas; Liquid which contains slag flows upwards and enters a floating slag separation area (8), liquid which contains no slag flows downwards and enters a gas-liquid separator (9), one part of effluent (10) is drained from a drain hole (11), and one part of the effluent (10) is refluxed to a dissolved gas pump intake pipe (12); an ultrasonic vibrator (13) and an ultraviolet light source (14) provide an ultrasonic and ultraviolet synergetic catalysis action; floating slag overflows to a collecting groove (15) and is drained through a drain hole (16); and a coagulant, powder activated carbon and hydrogen peroxide are added by adding systems (2, 3, 4) to provide a coagulation action and the synergetic catalysis action of PAC (powdered activated carbon) and H2O2. Tail gas is refluxed to the ozone generator through a drain hole (17), a one-way valve (18), gas suction tanks (19 and 20) and a dryer (23). The oxidation tower is compact in structure and has high treatment efficiency.
