摘要： PROBLEM TO BE SOLVED: To reduce the adverse effect of the oxidants contained in the stack gas desulfurization waste water on the microorganism in the treatment of the waste water discharged from a wet atack gas desulfurizing plant and to provide the method for treating the stack gas desulfurization waste water with high efficiency. SOLUTION: The sulfur oxides in a waste combustion gas are absorbed and removed by a wet stack gas desulfurizer. The waste water discharged from the desulfurizer is brought into contact with activated carbon under reducing conditions to decompose the oxidants in the waste water. Consequently, the subsequent biological treatment including nitration and denitrification is smoothly performed without adversely affecting the microorganism. Further, since the micropore diameter of the activated carbon is not broken by persulfuric acid, the deactivation of the activated carbon as a catalyst is prevented, and the exchange frequency is drastically decreased.
