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 deocmposition-treatment tank to activate the oxidizing agent, to thereby oxidization-decompose the organic chlorine compounds in the gas.
Claims4
A method for treating a liquid containing organic chlorine compounds, comprising,
- aerating a liquid containing organic chlorine compounds with a gas so that the organic chlorine compounds contained in the liquid are caught into the gas,
- collecting the gas containing the organic chlorine compounds, aerating a treatment solution containing an oxidizing agent with the gas containing the organic chlorine compounds to collect the organic chlorine compounds contained in the gas into the treatment solution, and
- irradiating ultraviolet rays to the treatment solution to activate the oxidizing agent so that the oxidizing agent decomposes the organic chlorine compounds in the treatment solution.
