Kind Code:
A
Abstract:
To provide sludge disposal equipment capable of balancing the reduction of excess sludge with the control of a mixed liquor suspended solid (MLSS) and an apparatus for highly efficiently reducing the excess sludge.
Microorganism cells constituting the sludge are destructed by jetting the sludge pressurized by a uniaxial eccentric screw type pump 53 to the inside of a solubilizing tank 54 through a nozzle to cause cavitation. After that, the sludge is distributed in a distribution tank 55 and a part of the sludge is returned to a joining tank 52. A thickener 7 is connected to the joining tank 52 and the sludge is concentrated in the joining tank 52 by circulating the sludge between the joining tank 52 and the thickener 7.
