Abstract

PURPOSE: To obtain treated water of stabilized quality by detecting ammonia concentration and flow rate of waste water introduced into a dipping adhesive biotic membrane treating unit and controlling the air amount to be introduced into an aeration chamber based on the result of detection.
CONSTITUTION: Waste water is introduced from a tube P1 into an aeration chamber 1 to aerate the waste water with air from the tube P3 and to introduce the waste water from the tube P2 into a dipping adhesive biotic membrane treating unit having a module unit 3 so as to purify the waste water by the operation of microorganisms. The purified water is returned through the tube P5 into an aeration chamber and treated water is drained from the tube P4. The ammonia concentration in the stock waste water is detected by a detector AE, and flow rate is detected by a detector FE1 to feed detected values to an arithmetic unit CC so as to control an air introduction amount control valve V1 based on the calculated result. However, the flow rate of the circulating water is retained always constantly by the detector FE2 and flow rate indication control meter FIC.
