<p>PROBLEM TO BE SOLVED: To obtain an absorbing solution showing high denitrification rate without pretreating a waste gas by using a solution prepared by dipping compost in a solvent to elute a dissolving component in the compost as the absorbing solution of nitrogen oxides. SOLUTION: Garbage is used as a raw material and is dried and adjusted to be 35% in water content and after that, charged into a compost making device to ferment, for instance, for 45 days while blowing air to make the compost. Next, a distilled water is added into the compost and stirred, for instance, for 24hr, the mixture is made to flow in a screen and a solution passing through the screen is used as the absorbing solution. Since the absorbing solution contains a material absorbing the nitrogen oxide, high denitrification rate is attained without pretreating the waste gas to increase the solubility of the nitrogen oxides at the time of treating the waste gas containing the nitrogen oxides with the solution.</p> |
