<p>PURPOSE: To improve oxidation of waste water drawn out of a wet type flue gas desulfurization equipment, in which magnesium hydroxide or oxide is used as a desulfurizing agent, with an oxidation column, to make the oxidation more efficient and to reduce the size of the oxidation column. CONSTITUTION: In this bubble column type oxidation of a waste liquid discharged from a magnesium process flue gas desulfurization equipment, the pH of oxidation column outlet liquid is detected and the pH of oxidation column inlet liquid is controlled with an alkaline agent so that the pH of the oxidation column outlet liquid is >=5.5 to reduce the volume of the oxidation column and the amount of oxidizing air to be introduced.</p> |
