The utility model provides a photocatalysis and wet process combination treatment volatile organic compounds's equipment, including the equipment casing, the cavity roof of equipment casing has hung central ultraviolet lamp support, and the bottom of central ultraviolet lamp support has hung central ultraviolet fluorescent tube, outside cover at central ultraviolet fluorescent tube is equipped with the inner tube, and the inner tube is to being formed with the intermediate layer cavity between the equipment casing, and the top of intermediate layer cavity is sealed through annular ultraviolet lamp support, it has a plurality of side ultraviolet fluorescent tube to suspend in midair in the intermediate layer cavity, the exhaust outlet that with intermediate layer cavity communicate is seted up at the lateral wall of equipment casing. The advantage does: (1 )Combine photocatalytic oxidation method in the VOCs processing method and wet process absorption process, form integration equipment, reduce area, (2 )Absorbing a large amount of waste water of VOCs production with traditional wet process and comparing, this technological waste water output is low to the effect that self purifies has, (3 )The O3 of equipment production in service obtains make full use of, and O3 concentration is low in the final waste gas that discharges.
