<p>PROBLEM TO BE SOLVED: To provide a waste gas treating apparatus which minimizes an amount of water used for the treatment of a waste gas containing pollutants, and in which a cleaning tower and an absorber are miniaturized. SOLUTION: The waste gas treating apparatus is provided with a water feeder 10 which injects water to the waste gas containing the pollutants, a cleaning tower 12 which separates and removes the pollutants from the waste gas, a concentrated waste water storage tank 14 which stores water containing the pollutants, water circulating devices 15 and 25 which circulate and supply the gaseous mixture of the waste gas and the water injected by the water feeder 10 to the water feeder 10 from the water feeder 10 through the cleaning tower 12 and the concentration waste water storage tank 14, and an adsorber 40 which adsorbs the pollutants in water separated by the cleaning tower 12. The concentration of the pollutants is increased by circulating water stored in the concentrated waste water storage tank 14, thereby the quantity consumed of water is greatly reduced.</p> |
