METHOD AND APPARATUS OF REDUCTION OF EXCESS ACTIVATED SLUDGE BY PHYSICAL SOLUBILIZATION REACTOR

摘要

The present invention relates to a sludge reduction method using a physical solubilizing device of surplus activated sludge and the apparatus; and comprises: (a) a surplus activated sludge inflow step (S11) which transports surplus activated sludge mixing water remained after a water treatment process in a settling tank (140) to a physical solubilizing device (150); (b) a first collision step (S12); (c) a surplus activated sludge pressurization step (S13); (d) a jet stream generation step (S14); a cavitation step (S15); (f) fourth collision step (S16); and a discharging step (S17), and thereby maximizing sludge reduction efficiency using the physical solubilizing device.
