TREATMENT METHOD FOR WASTEWATER CONTAINING HYDRAZINE AND AMMONIA

摘要

PROBLEM TO BE SOLVED: To provide a treatment method for wastewater containing hydrazine and ammonia capable of treating hydrazine and ammonia contained in wastewater at the same time in one stage and simplifying a treatment apparatus to enable the shortening of a treatment process. SOLUTION: In the treatment method for wastewater containing hydrazine and ammonia, the wastewater containing hydrazine and ammonia is subjected to aeration treatment using an oxygen-containing gas in the presence of a metal or metal ions under a pH condition of 9-13 and ammonia contained in the gas generated by aeration treatment is oxidized to be decomposed.
