Oxidization of ammonia desulfurization solution

A method for oxidizing an ammonia-bearing desulfurization solution, the method comprising:

• expanding air, at an air distribution stage in a tank, against the desulfurization solution, the air distribution stage configured to produce oxidation of the solution;
• enhancing the oxidation of the solution using an oxidation enhancing device;
• oxidizing the solution by the expanding and the enhancing, to produce oxidized solution;
• after the enhancing:
• exiting the oxidized solution from the tank via an absorption liquid outlet of the tank;
• then, adding ammonia to, and thereby increasing the ammonia content of the oxidized solution;
• then, providing the oxidized solution to a plurality of different sections of a flue gas desulfurization tower, the different sections including an absorption section;
• after the providing, reacting, in the absorption section, the oxidized solution with a flue gas, producing reacted solution;
• and,
• after the reacting, feeding the reacted solution to the tank.
