した回分式排水処理装置。 The treatment tank body, the aeration part provided at the bottom of the treatment tank body, the supernatant water drainage part, the level switch that detects the lower and upper water levels, the drainage input pump and the supernatant water drainage controlled by this level switch. A pump, an excess sludge extraction pump, an activated sludge suspended solids meter detection section provided below the lower water level, and a signal from this detection section is input to the excess sludge extraction pump and the supernatant water drainage pump. This control section determines whether or not the detection section is in activated sludge based on the magnitude of the signal from the detection section in the sedimentation state, and determines whether or not the detection section is activated. When in sludge,
A batch type wastewater treatment device characterized in that the activated sludge drawing pump is operated to draw out sludge to a level that does not interfere with supernatant water drainage.
