Abstract

PURPOSE: To treat waste water efficiently in simple operation in one reaction tank by a method wherein waste water is supplied to the tank in a denitrification stage and, thereafter, while an anaerobic condition is maintained, supply of waste water is stopped for a predetermined time and, subsequently, transferred to a nitration stage.
CONSTITUTION: Waste water 11 to be treated containing a water soluble nitrogen compound is introduced into a reaction tank 1 in a predetermined amount through a liquid sending pipe 5 by using a liquid sending pump 2. During a time T2 supplying the waste water to the reaction tank 1, denitrification due to anaerobic bacterial is mainly carried out and, during a time T4 wherein supply of the waste water is stopped to operate an air blower 3 and air is blown into the reaction tank 1 from an air blow-in means 4, nitration due to aerobic bacteria is mainly carried out. The waste water 12 after treatment is stored in a precipitation tank 7 through a transfer pipe 13 and, thereafter, discharged out of a system through a discharge pipe 10. A supply amount of the waste water is adjusted so as to coincide an average stay time in the reaction tank 1 with a set time.
