Provided is a method for treating water containing cyanogen and ammonia with which cyanogen and ammonia are sufficiently decomposed even in cases where the concentration of soluble iron is high. This method for treating wastewater containing cyanogen and ammonia involves a step for oxidizing and decomposing cyanogen and ammonia by adding a chemical solution including hypobromous acid and/or hypochlorous acid to wastewater containing cyanogen and ammonia. A solution in which hypobromous acid and/or a hypobromite have/has been produced by mixing a bromide aqueous solution and a hypochlorite aqueous solution is added to wastewater containing cyanogen and ammonia. A sodium bromide aqueous solution and a sodium hypochlorite aqueous solution are mixed and added at an equimolar ratio or such that sodium hypochlorite is excessive. |
