<p>PROBLEM TO BE SOLVED: To provide a suspended matter removing apparatus, in an aeration tank, especially, a batchwise sludge treatment tank in an aeration process or a stirring process, capable of sucking and discharging suspended matter effectively without providing a suspended matter gathering means, capable of always following the fluctuations of the water level in the tank, suppressing the whirling-up of the mixed liquid of the aeration tank at the peripheral edge of a suspended matter suction port and capable of discharging the suspended matter along with a small amt. of a liquid (aeration tank mixed soln.) while involving air. SOLUTION: A suspended matter removing apparatus for an aeration tank is equipped with a recovery plate member 4 provided with a suspended matter suction port 5a removing suspended matter 30, a suspended matter discharge apparatus 8 comprising the discharge means 6 formed so as to be connected to the suspended matter suction port 5a and the holding device 2 for holding the recovery plate member 4 of the suspended matter discharge apparatus 8 under the surface of the mixed soln. in the aeration tank. The holding device 2 is pref. the float 2 attached to the suspended matter discharge apparatus 8.</p> |
