When the water quality state of the treated water stored in the first settling tank 100 exceeds the discharged water quality reference value, the drive control unit 500 drives the first treated water transport pump 120 to operate the stored water stored in the first settling tank 100. It is configured so that treated water can be returned to the anaerobic tank 10, and at the same time, the anaerobic tank 10, the anoxic tank 20, and the aeration tank 30 can be driven.

In addition, the drive control unit 500 controls the first treated water transfer pump 130 connected to the first settling tank 100 when the water quality state of the treated water stored in the first settling tank 100 is less than the discharged water quality reference value. ) is driven to control the transfer of treated water.

In addition, the drive control unit 500 determines whether the water quality state information of the treated water stored in the second settling tank 200 exceeds the discharged water quality reference value, and the second treated water transport pump 220 or the second treated water transfer pump ( 230) is controlled.

At this time, the drive control unit 500 is a second treated water conveying pump ( 220) is controlled, and at the same time, the coagulation tank tank 420 connected to the coagulation tank 40 is opened so that a certain amount of sodium bicarbonate is introduced.

Meanwhile, the driving control unit 500 controls the driving of the raw water supply pump 12 according to the conveyance amount of the treated water stored in the first settling tank 100 .

That is, when the conveyed amount of the treated water to be returned is close to the limit storage amount of the anaerobic tank 10, the anoxic tank 20, and the aeration tank 30, the raw water supply pump 12 is stopped to stop the raw water to be treated from the flow tank By preventing supply to the anaerobic tank 10 by preventing the raw water to be treated or the treated water to be conveyed from overflowing from the anaerobic tank 10.

In addition, the drive controller 500 may store water quality state information of the treated water transmitted from the water quality check controller 480 .
