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.
Claims3
An apparatus for treating a liquid containing organic chlorine compounds comprising,
- an aeration tank for retaining a liquid containing organic chlorine compounds to be treated,
- means for supplying a gas into the liquid retained in the aeration tank while aerating so that the organic chlorine compounds contained in the liquid is caught into the gas,
- a decomposition-treatment tank for retaining a treatment solution containing an oxidizing agent,
- means for collecting the gas containing the organic chlorine compounds in the aeration tank and providing the gas to the decomposition-treatment tank while aerating to collect the organic chlorine compounds contained in the gas into the treatment solution, and
- an ultraviolet lamp situated in the decomposition-treatment tank for irradiating ultraviolet rays to the treatment solution to activate the oxidizing agent in the treatment solution so that the oxidizing agent decomposes the organic chlorine compounds in the treatment solution.
