In addition, adsorptive oxidation treatment materials
When the UV lamp is placed in the storage compartment, the ultraviolet lamp is placed in the vicinity of the storage cartridge. In particular, when the adsorption oxidation treatment material and the granular activated carbon are separately stored in the adsorption oxidation treatment material layer and the granular activated carbon layer, the adsorption oxidation treatment material layer is arranged so that ultraviolet rays are irradiated on the side. It Further, when the cartridge-shaped bodies are arranged in multiple stages, they are arranged between the respective cartridge-shaped bodies.

る。The pollutants such as odorous substances in the gas to be treated introduced into the treatment tower are adsorbed on the surface of the carrier and the particulate titanium dioxide. In addition, the ultraviolet rays from the ultraviolet lamp sterilize the gas and at the same time oxidize and decompose the organic matter due to contaminants in the gas, and also oxidize and decompose the organic matter adsorbed on the surface of the carrier and the particulate titanium dioxide.

を維持する。Further, when the titanium dioxide is irradiated with ultraviolet rays, the titanium dioxide is photoexcited, and it is adsorbed on the surface of the carrier and the particulate titanium dioxide by the strong oxidizing power of active oxygen, hydrogen peroxide, OH radicals, etc. generated thereby. Since organic substances such as pollutants are oxidatively decomposed, the adsorption of the adsorbent-oxidized material does not reach a breakthrough and always maintains a constant adsorption efficiency.

And then discharged from the treatment tower. On the other hand, the adsorptive oxidation-treated material is successively conveyed to a regeneration tower where it is irradiated with ultraviolet rays, and the organic matter adsorbed on the surface of the particulate titanium dioxide and the organic matter adsorbed on the carrier itself are oxidatively decomposed ( After being regenerated), the adsorptive oxidation treatment material returns to the treatment tower again.

後、下方の導管７から排出される。In FIG. 1, in the gas treatment apparatus 1, granular adsorption and oxidation treatment materials 4 are deposited and arranged on a mesh body 3 in a treatment tower 2.
The adsorptive oxidation treatment material 4 is made by fixing fine particles of titanium dioxide on the surface of diatomaceous earth, which is a granular carrier, or by mixing granular activated carbon with this. In the adsorptive oxidation treatment material 4, a plurality of ultraviolet lamps 5 housed in respective transparent jackets are vertically arranged. The gas to be treated is supplied from the upper conduit 6 at a flow rate such that the adsorptive oxidation treatment material 4 does not fluidize, passes through the adsorption oxidation treatment material 4, and is then discharged from the lower conduit 7.

の場合には担持体自身によっても行なわれる。As the gas to be treated introduced from the conduit 6 into the processing tower 2 passes through the deposited layer of the adsorptive oxidation treatment material 4 from the top to the bottom, the pollutants in the gas to be treated become the adsorption oxidation treatment material 4 The processing gas after being adsorbed by the exhaust gas and adsorbing and removing the contaminants is discharged from the conduit 7. The adsorption is also carried out by means of finely divided titanium dioxide fixed on the surface of the carrier, and also by the carrier itself if the carrier is adsorptive.

The deposition layer of the adsorption oxidation treatment material 4 does not flow up to a certain gas flow rate, and the deposition layer state is maintained to form a fixed bed.

ないで、常に一定の吸着効率を維持する。Further, the ultraviolet rays from the ultraviolet lamp oxidize and decompose the organic substances constituting the pollutants in the gas to be treated, as well as the organic substances adsorbed on the surfaces of the carrier and the particulate titanium dioxide. When titanium dioxide is irradiated with ultraviolet rays, the titanium dioxide is photoexcited, and the organic substances adsorbed on the surface of the particulate titanium dioxide and the carrier itself due to the strong oxidizing power of active oxygen, hydrogen peroxide, OH radicals, etc. generated thereby. Since the organic substance adsorbed on the substrate is oxidatively decomposed, the adsorption effect of the adsorptive oxidation treatment material 4 does not decrease, and a constant adsorption efficiency is always maintained.

It becomes the floor. The sterilization and adsorptive oxidation actions are the same as in Example 1, but a larger amount of gas can be treated than in Example 1.

が低下せずに高い吸着状態を維持する。By irradiating the gas to be treated or the adsorbent-oxidized material with ultraviolet rays, the gas to be treated or bacteria adsorbed on the surface of the adsorbed-oxidized material is sterilized, and the adsorbent-oxidized material is adsorbed. The titanium dioxide is photoexcited, and the strong oxidizing power of active oxygen, hydrogen peroxide, OH radical ions, etc. oxidizes and decomposes the organic substances constituting the pollutants adsorbed in the gas or the adsorbed oxidation treatment material. As a result, not only the titanium dioxide in the form of fine particles but also the carrier is regenerated, so that the adsorption oxidation treatment material does not reach the adsorption breakthrough and the adsorption ability is not lowered, and the high adsorption state is maintained.
