Abstract

PURPOSE: To decrease the site required for installation of a treating tank and improve the performance of denitrification and the economy of equipment by providing a cylindrical body communicating with the down stream side of a circulation flow passage for denitrification provided in a treating tank formed in a relatively deep shape.
CONSTITUTION: A treating tank 1 of a relatively deep shape is installed in the state of burying the greater part of its lower side in ground, and a cylindrical body 2 is erected with its bottom end part near the bottom of the tank 1. A circulation flow passage 5 for denitrification lifting the water from the 1st defoaming tank 4 formed in the upper part of the tank 1 to the top end of the body 2 is provided by the 1st partition wall 2 and a flow passage 6 supplying the ammoniac nitrogen-contg. water to be treated to the tank 4 is provided. The water to be treated is circulated and flowed in the state of contg. activated sludge of high concn. through the tank 4, the passage 5, the down flow passage in the body 2 and the up flow passage in the tank 1 in this order.
