Abstract:
1. An advanced wastewater treatment device having movable dividers, comprising: a wastewater treatment bath comprising: a second movable divider separating the anoxic bath from the aerobic bath, and movably provided in the wastewater treatment bath to change relative volume of the anoxic bath and the aerobic bath; a divider moving unit for moving the first and second movable dividers; an air supply unit supplying air to the aerobic bath and comprising: a recycling unit for recycling activated sludge of the aerobic bath to the anoxic bath; at least one contact sensor detecting a position of the second movable divider; and a control unit determining the position of the second movable divider based on detected data transmitted from the contact sensor, and providing a control signal to selectively control on/off operation of respective ones of the valves dependent upon the detecting resulting in only the valves which correspond to the air nozzles located in the aerobic bath divided from the anoxic bath by the second movable divider being open, thus supplying air only through the air nozzles located in the aerobic bath.
