摘要:
A system for decomposing a liquid or gaseous organic compound comprises a ultraviolet decomposition unit and an intermediate product treatment apparatus. The ultraviolet decomposition unit decomposes an organic compound contained in polluted liquid or polluted gas by irradiating ultraviolet rays whose wavelength is less than 300nm to the polluted liquid or the polluted gas containing the organic compound. An acid electrolytic water feed pipe and an alkali electrolytic water feed pipe are respectively connected to the intermediate product treatment apparatus through valves to neutralize an intermediate product, which results from decomposition of the organic compound, for decomposition by selectively adding strong alkali electrolytic water and strong acid electrolytic water to the polluted liquid or the polluted gas containing the intermediate product.

The invention relates to a method for decomposing bromate ions contained in a liquid. The method includes the sequential steps of bringing the liquid into contact with a photocatalyst; and irradiating the photocatalyst with a light ray having an energy that is not lower than that of a band gap of the photocatalyst, thereby generating a photocatalytic reaction to decompose the bromate ions. The invention further relates an apparatus for decomposing bromate ions contained in a liquid. The apparatus includes a first section for generating therein a photocatalytic reaction to decompose the bromate ions; a photocatalyst adapted to be brought into contact with the liquid in the first section; and a light source for irradiating the photocatalyst with the light ray such that the photocatalytic reaction is generated in the first section when the photocatalyst is in contact with the liquid. Thus, it is possible to efficiently and stably decompose the bromate ions. The photocatalyst may be at least one metal oxide including titanium and a metal having an electronegativity lower than that of titanium. In this case, it is possible to omit pH adjustments of the liquid before and after the photocatalytic reaction.

The invention relates to a treatment method of waste comprising the steps of: throwing waste into a cylindrical-vertical type heating container; forming a fluidized layer of waste by blowing, as'agitating the thrown waste, gas into the cylindrical-vertical heating container from a gas blowing opening; heating the fluidized layer; and separating and exhausting the heated waste and gas. In this method, the harmful matters of dioxins contained in the waste may be easily and surely made harmless.

There is provided a new and useful method for the controlled reduction of organic material comprising subjecting the material to microwave radiation in a reducing atmosphere. An apparatus for carrying out the method comprises an airtight microwave chamber, means for feeding the organic material into the chamber, at least one microwave generator in the chamber, means for removing gaseous products from the chamber and means for removing solid residue from the chamber.
摘要:
Von eisenhaltigen Stoffen befreites Material wird in eine Grobfraktion und eine Feinfraktion getrennt und die Feinfraktion in die Primärkammer (2) eines Oberflächenschmelzofens (1) eingeleitet. Im Oberflächenschmelzofen (1) wird eine Luftzahl von λ = 0,7 bis λ = 1,3 eingestellt. Das geschmolzene Material verläßt die Primärkammer (2) zusammen mit dem Rauchgas. Das geschmolzene Material wird durch die Sekundärkammer (5) geleitet und als Schlacke ausgetragen.
