Improved oxidation system for the treatment of repelling odors and toxic substances of foundry waste and process for the treatment of the same

摘要

The present invention provides a more advanced oxidation system for the treatment of repelling odors and toxic substances of foundry waste, for example, sand, and a process for the treatment of the same is available that repelling odors and toxic substances can be removed effectively, which during a process for the also for the preparation of foundry waste are produced. For this purpose, a more advanced oxidation system for the treatment of repelling odors and toxic substances of foundry waste from the implement a spraying device for spraying a dilute solution of hydrogen peroxide to the foundry waste; a stirring device for mixing the foundry waste with the dilute solution of hydrogen peroxide, which was sprayed thereon; a uv - irradiating device for activating of the hydrogen peroxide, which is mixed with the foundry waste, in order to produce free radicals; and a suction device in situ in the trapping of dust, which is generated when the foundry waste with the hydrogen peroxide are mixed by the stirring device, formed.
