| 摘要 |
The present invention relates to an advanced wastewater treatment apparatus, which are capable of performing suction and discharging while automatically tracking heights of supernatant and sludge by means of a 3D transfer mechanism. The advanced wastewater treatment apparatus comprises: a control unit (70) which, when a water level (23a) of supernatant (23) detected by a water level sensor (S1) is close to a water level (24a) of sludge (24) detected by a water level sensor (S2) within a predetermined distance, performs control so that operation of a first pump (P1) is stopped and a second pump (P2) is operated, thereby proceeding to a process of discharging the sludge (24); an air pipe (39) which is connected between an air blower (76) and an air diffuser disk (30), and which transfers air, discharged by the air blower (76), to the air diffuser disk (30) at high pressure; and a discharge pipe (49) which passes through a center of the air pipe (39), is connected between inlets of the first pump (P1) and the second pump (P2) and a suction disk (40), and guides the supernatant (23) and the sludge (24), sucked via the suction disk (40), to the first pump (P1) and the second pump (P2). |
