Abstract

PURPOSE: To prevent rotting within a denitrification tank and carry out denitrification treatment in good efficiency by providing an apparatus wherein a stirring device is automatically stopped to take out activated sludge from said denitrification tank when a detected value of the activated sludge concn. exceeds a set value.
CONSTITUTION: To a nitration tank 1 provided with a deep downward flow passage r1 and an upward flow passage r2 connected to a lower section thereof, a denitrification tank 3 equipped with a stirring device 9 is connected and an apparatus 10 for detecting the activated sludge concn. is provided within a denitrification tank 3 and an apparatus 1 wherein the stirring device 9 is automatically stopped to take out precipitated activated sludge from said denitrification tank 3 when the detected value exceeds a set value is provided to construct a water treating apparatus. In this apparatus, oxygen gas can be dissolved under pressure and the concn. of activated sludge in the nitration tank 1 can be increased without lowering the sludge activity while treating efficiency is enhanced by carrying out the nitration treatment with high concn. activated sludge.
