Abstract

PURPOSE: To provide the subject device wherein sensers each detecting the oxygen consuming speeds in activated sludges are provided in the vicinities of the inlet part and the exhaust part of an aeration tank, and the air feed quantity and the sludge returning quantity are automatically controlled in response to the difference between the outputs of both sensers thereby to facilitate the water quality control.
CONSTITUTION: When water pollution quantities in the inlet part 2 and the exhaust part 3 of an aeration tank 1 consisting a single tank or a plurality of serial tanks are designated by SO and Sn respectively, and oxygen-consuming speeds in the activated sludges by r1 and rn, respectively, the following equation is established. r1 - rn = a' (So - Sn) Accordingly, if the proportion constant a' is measured beforehand, one can recognize the pollution assimilation state in the aeration water by sensers 7a and 7b for detecting the value of r. Automatic control means 15 operated in response to the difference of the outputs of both sensers is provided thereby to control a blower 9 for feeding air to the aeration tank and a pump 12 sending a precipitated sludge 11 in a precipitation tank 10 back to the aeration tanks, whereby the biological treatment of polluted water can be controlled rapidly and easily.
