the dissolved oxygen measuring instrument is arranged in the aeration blank area and is used for detecting the content of the dissolved oxygen in the sewage in the area, the aeration blank area is a middle water area of the water areas surrounded by the four aeration points, and the aeration effect of the area is the lowest as the area is positioned at the farthest position of the aeration action range of each aeration point;
aeration point includes air-blower, gas transmission pipeline and shower nozzle, the shower nozzle includes:
the air inlet is fixedly arranged at the tail end of the air pipeline;
the fairing is fixedly arranged on the air inlet, and the upper surface of the fairing is provided with a plurality of air holes;
a wedge-shaped splitter having a tip mounted downwardly within the fairing, the tip being hinged to an inner sidewall of the fairing;
the 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 part is in signal connection with the dissolved oxygen measuring instrument and the driving device and is configured to:
when the dissolved oxygen measuring instrument detects that the dissolved oxygen content of the sewage is smaller than a first value, the driving device is controlled to drive the flow divider to swing 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, and the opening of the air outlet area at one side close to the aeration blank area is increased;
along with the increase of the dissolved oxygen content of the water body in the aeration blank area, the control driving device drives the flow divider to gradually swing towards the direction close to the aeration blank area, so that the opening of the air outlet area at one side close to the aeration blank area on the fairing is reduced, and the opening of the air outlet area at one side far away from the aeration blank area on the fairing is increased, and the aeration effect of a wider water area outside the aeration blank area is ensured;
wherein the swing speed and/or swing amplitude of the diverter is inversely proportional to the dissolved oxygen content, i.e. the lower the dissolved oxygen content, the greater the swing speed and/or swing amplitude of the diverter in a direction away from the aeration blank area.
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.
