| titleOfInvention | Denitrification method for waste liquid containing organic nitrogen |
| abstract | (57) Abstract: At least EDT, which does not depend on biological treatment. To provide an efficient denitrification method for a waste liquid containing A as organic nitrogen. SOLUTION: In a denitrification treatment of a waste liquid containing at least ethylenediaminetetraacetic acid (EDTA) as organic nitrogen, the waste liquid is subjected to (1) a step of removing a metal chelated by EDTA under an alkaline pH, (2) a strong acid PH It is characterized in that the step of precipitating and removing EDTA from which the chelate metal has been removed and (3) the step of irradiating the remaining organic matter with ultraviolet rays in the presence of hydrogen peroxide and ozone to decompose and remove it are carried out in order from (1). A method for denitrifying waste liquid containing organic nitrogen. |
