a wedge-shaped splitter having a tip mounted downwardly within the fairing, the tip being hinged to an inner sidewall of the fairing;
the second driving device is connected with the shunt and is used for driving the shunt to swing in the fairing;
the upper end of the flow divider divides the air outlet of the fairing into two air outlet areas, the opening sizes of the two air outlet areas are changed due to the swing of the flow divider in the fairing, and the aeration air flow from the air transmission pipeline is guided by the wedge surface of the flow divider to be divided into the air outlet areas and is sprayed out from the air holes on the upper surface of the fairing at an inclined angle;
the control section is configured to:
(1) when the dissolved oxygen measuring instrument detects that the dissolved oxygen content of the sewage is smaller than a first value, the second driving device is controlled to drive the flow divider to move towards the direction far away from the aeration blank area, so that the opening of the air outlet area at one side of the fairing far away from the aeration blank area is reduced, the opening of the air outlet area at one side close to the aeration blank area is increased, more gas is sprayed to the aeration blank area, and meanwhile, the first driving device is controlled to drive the spray head to repeatedly lift in the water body, so that the uniform distribution and dissolution speed of the oxygen in the sewage water body are accelerated;
(2) along with the improvement of the dissolved oxygen content of the water body in the aeration blank area, the second driving device is controlled to drive the flow divider to gradually move towards the direction close to the aeration blank area, so that the opening of the air outlet area at one side of the fairing close to the aeration blank area is reduced, the opening of the air outlet area at one side of the aeration blank area is increased, and the aeration effect of a wider water area outside the aeration blank area is ensured.
The invention has the beneficial effects that: the working state of the aeration point can be changed according to the water body dissolved oxygen content information of the aeration blank area collected by the dissolved oxygen measuring instrument, so that the gas is close to the area as much as possible, and the balanced aeration of each area of the sewage is realized.
