The separation discharge device of low-density sludge, the system including it, and the operation method thereof

摘要

The present invention relates to water treatment, and more particularly, to a device for separating and discharging low specific gravity sludge from a mixed solution of a bioreactor, a system including the same, and an operating method thereof. To this end, the sludge separation tank 100 in which the bioreactor mixed solution 210 is accommodated; A plurality of inclined plates 180 are defined at a predetermined height from the bottom of the sludge separation tank 100 and installed on the inclined surface 157 to separate the low specific gravity sludge 220 and the high specific gravity sludge 230 up and down. ); Rotating means for rotating the swash plate 180; and a low specific gravity sludge pipe 160 installed on one side of the swash plate 180 to discharge the low specific gravity sludge 220; a device for separating and discharging low specific gravity sludge is provided.
