Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for waste water disposal which very efficiently disposes of a large amount of waste water containing various kinds of organic matter discharged from actual operations.SOLUTION: The apparatus for waste water disposal includes a treatment tank 1 in which waste water containing organic matter is treated, an ozone oxidation means which turns the organic matter included in the waste water in the treatment tank 1 into carbonyl compounds on oxidation with ozone, a solid-liquid separation means which precipitates the carbonyl compounds obtained by the ozone oxidation means with metal ions, and an ultraviolet irradiation means 4 which promotes the ozone oxidation reaction in the ozone oxidation means on ultraviolet irradiation. In this method, an organic matter is not decomposed, but ozone-oxidized into carbonyl compounds which are separated from the liquid on precipitation by means of chelate reaction with metal ions. This method, therefore, results in a large reduction of ozone consumption and a significant shortening of the treatment time.
