Abstract

The invention discloses a device and a method for efficiently degrading ozone through three-phase synergism. The device comprises an atomization system, a spray tower with a gas absorption pump and an auxiliary system, wherein an organic matter modified activated carbon layer is arranged in the spray tower. Ozone gas is forcibly sucked by an absorption pump, is in countercurrent contact with organic matter fog drops after being enriched by an adsorption layer, and is synergistically degraded under the conditions of ultraviolet excitation and constant temperature. When a 0.5 g / L cysteine-ascorbic acid-glutathione mixed solution (pH = 9.4) is adopted, the ultraviolet intensity is 1.34 W / m < 2 >, the temperature is 39.5 DEG C, the adding height of the activated carbon is 2.54 cm, the gas flow rate is 21.1 L / h, and the ozone degradation rate reaches 90.957%. The device is particularly suitable for microenvironment ozone purification.
