Abstract

PURPOSE: To realize the saving of the motive power, the elimination of an excessive attachment of the berm substance and the increase of the denitrifying efficiency each, by carrying out the denitrifying treatment via the sealed rotary disk type organism chemical treatment device.
CONSTITUTION: The denitrification bath 16 contains the outer wall 18 and the roof 17; and the rotary disk group P is supported by the shaft. The nitrogen gas is jetted to the group P from the lower part, and thus the bubbles stay in the cup 11. Then the group P turns in the direction of the arrow by the buoyancy. As a result, the gas prevails up to the every corner of the rotary disk to give a highly efficient denitrification to the nitrate and nitrite nitrogen contained in the waste water. And at the same time, the desired purpose can be attained.
