Abstract
Process and apparatus for decomposing halogenated aliphatic hydrocarbon compounds in the presence of functional water under light irradiation, where the target substance for decomposition contained at a low concentration in the exhaust or discharge from the decomposition unit is adsorbed by an adsorption unit, and at regular intervals, the adsorbed target substance is released from the adsorption unit and returned to the decomposition unit. The concentration of the target substance in the waste or discharge can be easily and efficiently reduced below the environmental standard.
