Abstract
PURPOSE: To dispose a highly concentrated waste liquid without diluting it or adding any reagents to it in only a few days, by aligning the first nitrification vessel, the first denitrification vessel, the second nitrification vessel and the second denitrification vessel in this order to perform nitrification and denitrification.
CONSTITUTION: A highly concentrated waste liquid 1 is nitrified in the first nitrification vessel 3, to remove most of BOD and T-N from the waste liquid. At this time, NH4-N is oxidized into NO2-N, which, in turn, is converted into N2, too. The waste liquid is then denitrified in the first denitrification vessel 8 to remove NO2-N. A portion of the primary denitrified liquid 9 obtained in this vessel 8 is cyclically fed to the first nitrification vessel 3, while the remainder is nitrified in the second nitrification vessel 11. At this time, NH4-N in the liquid is completely oxidized and removed. Thereafter, the liquid is denitrified in the second denitrification vessel 14, to completely remove NO2-N or the like which was formed by oxidation of NH4-N in the second nitrification vessel 11.
