Method of degradation of volatile organic compounds in waste air |
| abstract |
The invention relates to a method of degradation of volatile organic compounds in waste air, comprising the steps of supplying waste air to a first reactor (1), where it is irradiated with UV radiation at a wavelength below 200 nm to form photolytic decomposition intermediates, wherein ozone is produced; removing the waste air and the photolytic decomposition intermediates from the first reactor (1) and introducing them into a second reactor (2), where they are brought into contact with an aqueous solution of hydrogen peroxide; irradiating the aqueous solution of hydrogen peroxide, the waste air and the photolytic decomposition intermediates with UV radiation at a wavelength above 200 nm to form photochemical decomposition products, wherein hydroxyl radicals are produced; and removing the purified waste air including the photochemical decomposition products and being at least partially free of volatile organic compounds from the second reactor (2). The concentration of ozone produced is in the range 185-240 ppm at a first reactor outlet (4) and the concentration of hydrogen peroxide in the aqueous solution is in the range of 0.80-1.15 wt. %. |
