Abstract

PURPOSE: To perform not only denitrification but also the lowering of BOD by the procedure in which part of treated water in nitrification process is supplied distributionally to each section of denitrification process where organic polluted water supplied is denitrified and the treated water of the denitrification process is all supplied to nitrification process.
CONSTITUTION: The organic polluted water A, pretreated to remove dust and sands in advance, is first supplied distributionally to each of the first tank 2a and the fourth tank 2d of the first denitrification tank 1 and also the treated water B of the subsequent nitrification tank 3 is supplied distributionally to each of these tanks. The mixed treated water C of the first denitrification tank 1 is then supplied to the nitrification tank 3 where it undergoes nitrification treatment under aerobic condition, and most of the treated water B of the nitrification tank 3 are sent back to the first denitrification tank 1 but the remainder is sent to the second denitrification tank 4 where it undergoes denitrification treatment with methanol injected as the organic substance E and N2 gas is released.
