Abstract

PURPOSE: To save consumption of chemicals and thus prevent degradation in quality of water after treatment, by applying biological denitrification treatment to waste water with addition of hydrogen supplying substances (organic carbon source), and controlling the amount of said hydrogen supplying substances to be added by detecting concentration of nitrite nitrogen contained in waste water after the above first process of denitrification treatment.
