PROBLEM TO BE SOLVED: To provide a method for removing dissolved sulfide and an apparatus therefor by which dissolved sulfide can be removed directly and efficiently from water (raw water) such as wastewater. SOLUTION: The apparatus A is composed of: an apparatus body 1 equipped with an activated carbon layer 6 in a treatment tank 5; a raw water supply means 2 by which the raw water W with dissolved sulfide is supplied and allowed to flow through the activated carbon layer 6; and a gas supply means 3 by which gas S containing oxygen is supplied into the treatment tank 5 and allowed to flow through the activated carbon layer 6. Then, the raw water W and the gas S are allowed to flow simultaneously through the activated carbon layer 6, thereby oxidizing the dissolved sulfide by utilizing catalysis of the activated carbon, and converting it to sulfur for removal.
