摘要： A process for the treatment of water with ozone in which trace amounts of organic substances contained in water to be treated are oxidized and decomposed by diffusing ozone into the water introduced into a reaction tank, by injecting a chelate compound into the water to be treated after or just before the introduction of the water into the reaction tank. Preferred chelate compounds include ethylenediaminetetraacetic acid disodium salt, ethylenediaminetetraacetic acid calcium salt, ethylenediaminetetraacetic acid magnesium salt, ethylenediaminetetraacetic acid iron salt and iron citrate.
