Abstract
PURPOSE: To remove COD components rapidly and efficiently with a simple equipment and a low operating cost by a method wherein a liquid to be treated is subjected to an aerating treatment after adding at least one catalystic substance selected from the group consisting of ions of metals such as Fe, Ca, Mn and the like and compounds thereof.
CONSTITUTION: Into the liquid to be treated which is derived from desulfurization in a wet-type exhaust gas desulfurizer or the like, at least one selected from the group consisting of ions of metals such as Fe, Ca, Mn and the like and compounds thereof is added as a catalytic substance. Then, the liquid to be treated is aerated in the atmosphere, whereby the COD In the liquid can be decreased rapidly.
