よう構成せられた上澄水放流制御装置。 A transmission type light beam is applied to the support body 6b which is extended laterally from the lower part of the stem 6a guided into the sewage treatment tank 1, so that the light emitting surface 7a and the light receiving surface 7b face each other at a predetermined distance through the tank liquid. By arranging the sensing section 7 of the sensor, the light emitting surface 7a and the light receiving surface 7b can be
is located below the outlet 5 of the supernatant water discharge device 3 and away from directly below the stem 6a, and the sludge interface l2 is located below the location of the optical sensor sensing section 7. It detects this and drives the supernatant water discharge device 3, and also detects that the sludge interface l2 is above the location of the optical sensor sensing section 7 and stops the operation of the supernatant water discharge device 3. A supernatant water discharge control device configured as follows.
