PROBLEM TO BE SOLVED: To provide a contaminated water-cleaning apparatus which can be operated with a low exchange frequency of activated carbon by using an adsorption device using the activated carbon and reduced in cleaning cost and which is able to save the space. SOLUTION: The contaminated water-cleaning apparatus has a contaminated water-storing device for storing the contaminated water containing volatile contaminates, a mixing device for mixing the contaminated water stored in the contaminated water-storing device with gaseous ozone, an ultraviolet ray irradiating device for irradiating the contaminated water with ultraviolet rays, an aeration device for bringing the contaminated water irradiated with the ultraviolet rays into contact with a gas for the aeration, an adsorption device using activated carbon for adsorbing the volatile contaminates in the gas discharged from the aeration device after aeration and a treated water storing device for storing the treated water treated by the aeration device. |
