Abstract:
1. A method of oxidizing hydrogen- and carbon-containing molecules of pollutant substances in water-containing air exhausted from a manufacturing operation, the exhausted air having a content of pollutant substances that can vary in composition and amount, the method comprising: continually adding a quantity of ozone to a flowing stream of the air; adding water, if necessary, to the flowing stream; continually passing the ozone-containing and water-containing air stream through a flow passage for oxidation of the pollutant substances, the flow passage having a flow passage inlet and a flow passage outlet; progressively subjecting the ozone-containing and water-containing air stream to ultraviolet radiation along the flow passage to progressively form hydroxyl radicals for continual oxidation of the pollutant molecules as the air stream flows along the flow passage; continually discharging the air stream from the flow passage outlet; analyzing the discharged air stream to obtain a measure of any residual quantities of ozone and pollutant substances; and using measured quantities of ozone and pollutant substances in control of addition of ozone and the quantity of UV radiation.
