Abstract
PURPOSE: To perform a denitrification treatment of nitrogeneus organic compounds contained in waste liquid stably by making the 1st and the 2nd aerating vessel of an aerobic type of a tightly closed vessel respectively, and supplying an oxygen-enrich- gas into the 1st aerating vessel, then reusing its waste gas in the 2nd aerating vessel.
CONSTITUTION: Organic waste liquid 6 to be treated is passed through a treating process alined the 1st agitating vessel 1 of an anaerobic type, the 1st aerating vessel 2 of an aerobic type, the 2nd agitating vessel 3 of an anaerobic type, the 2nd aerating vessel 4 of an aerobic type and a solid-liquid separating vessel 5 in this order, and then a separated liquid in the vessel 5 is discharged as a treated liquid. Wherein, the vessel 2 and the vessel 4 are made of a tightly closed vessel respectively, and are communicated in each gas-phase part by a communicating pipe 11 of an aerobic type; through a sladge-returning path 9 a separated sladge in the vessel 5 is returned to the vessel 1; and through a mixed liquid circulating path 8 a mixed liquid in the vessel 2 is circulated and is forced to contact with an organic waste liquid for mixing in an anaerobic atmosphere.
