TREATING APPARATUS OF WASTEWATER INCLUDING VOLATILE ORGANIC SUBSTANCE AND TREATING METHOD THEREOF

PROBLEM TO BE SOLVED: To provide a treating apparatus of wastewater which allows a volatile organic substance in the wastewater to be subjected to the treatment economically and efficiently. SOLUTION: This treating apparatus of wastewater is constituted in such a manner that the wastewater which is supplied from a wastewater supplying means 1 and includes the volatile organic substance is treated in an aeration treatment chamber 10, the wastewater is, thereby, subjected to the gas-liquid separation and separated into the gas including the volatile organic substance and the water gotten rid of the volatile organic substance, the gas including the volatile organic substance is transferred into a normal pressure low temperature micro wave plasma device 20 and subjected to a plasma decomposition treatment, the gas after treated is subjected to an adsorption treatment on an activated carbon treating column 31, after a constant period, the volatile organic substance which is adsorbed on the activated carbon material 32 is liberated by steam supplied from a steam supplying means 41, the generated gas is condensed by a cooler 42 and the condensed water is transferred into the waste supplying means 1.
