Degrading aqueous peracetic acid by degrading acid by oxidization treatment of free radical in degradation products, and adding hydrogen peroxide to peracetic acid, where radicals is formed by irradiating substance with UV radiation

摘要

The method comprises degrading peracetic acid by oxidization treatment of free radical in degradation products, and adding hydrogen peroxide to the peracetic acid. The free radicals are formed by irradiating a free radical forming substance with high-energy UV radiation in a reactor (8) and by an electrochemical reaction of the free radical forming substance. The free radical forming substance is water or an aqueous solution. The electrochemical reaction is carried out in the reactor. The reactor comprises an electrode. The free radical forming substance is adsorbed on an adsorbent. An independent claim is included for a device for degrading aqueous peracetic acid.
