Chemical denitrification of NO2-N conducted with amido sulfonic acid was studied to treat NO2-N in both bench and in situ experiments. In bench experiments, following optium conditions for NO2-N removal were obtained. The dosage of amide sulfate was 6.9 times equivalent to NO2-N load, pH value and stirring rate were 2.5 and 50 r.p.m., respectively in the bench reactor, and the period for reaction was more than 60 minutes. Nitrogenous gases like NOx and N2O, which are causative materials for air pollution and global warming, were not detected in the gas exhaust.<br>In situ experiment was made with wastewater containing NO2-N discharged from a factory and with its operating parameters same as the optimum conditions obtained in the bench experiment. It ran in batch style and was controlled automatically. Results showed that efficient chemical dentrification could be conducted through continuously striring during treated wastewater discharging, and through covering nitrite sensor to keep it from the nitrogenous gases generated in the reaction.
