Abstract
Raw water containing organic chlorine compounds is supplied in an aeration tank, wherein the organic chlorine compounds contained in the raw water are transferred into air or gas. The gas obtained from the aeration tank is collected in a treatment solution of a decomposition-treatment tank. The treatment solution contains an oxidizing agent and ultraviolet rays are irradiated to the treatment solution in the decomposition-treatment tank to activate the oxidizing agent, to thereby oxidization-decompose the organic chlorine compounds in the gas.
