Embodiment
Embodiment:
Structural representation of the present utility model as shown in Figure 1; aerobic aeration automaton of the present utility model; include dissolved oxygen probe 1; dissolved oxygen sensing transmitter 2; power-supply controller of electric 3; blower fan 4; airduct 5; the dissolved oxygen probe 1 that wherein can detect the sewage oxygen content in the Aerobic Pond 6 places Aerobic Pond 6; and the detection signal output terminal of dissolved oxygen probe 1 is connected with the input end of dissolved oxygen sensing transmitter 2; the output terminal of dissolved oxygen sensing transmitter 2 is connected with the signal input part of power-supply controller of electric 3; the signal output part of the power-supply controller of electric 3 of 4 runnings of control blower fan and shutdown is connected with blower fan 4; the air intake vent of the air outlet of blower fan 4 and airduct 5 joins, and the air outlet of airduct 5 places Aerobic Pond 6.In the present embodiment, dissolved oxygen probe 1 places under the high liquid level (HLL) A of Aerobic Pond 6.
In the present embodiment, above-mentioned dissolved oxygen sensing transmitter 2 is provided with start driving switch and shutdown driving switch.
In the present embodiment, the start driving switch of above-mentioned dissolved oxygen sensing transmitter 2 is provided with 0mg/L, 0.5mg/L, 1.0mg/L, 1.5mg/L, four starts of 2.0mg/L gear.The shutdown driving switch of above-mentioned dissolved oxygen sensing transmitter 2 is provided with 2.0mg/L, 2.5mg/L, four shutdown of 3.0mg/L, 3.5mg/L gear.
Principle of work of the present utility model is as follows: be arranged at 1.0mg/L as the start gear with dissolved oxygen sensing transmitter 2; when the shutdown gear is arranged at the 2.0mg/L gear; at first start blower fan 4; this time the dissolved oxygen DO in the waste water is lower; the start driving switch of dissolved oxygen sensing transmitter 2 is in normally off; dissolved oxygen sensing transmitter 2 is by current signal control power-supply controller of electric 3 closures; power-supply controller of electric 3 control blower fans 4 constantly turn round; give in the Aerobic Pond 6 and charge into air; prolongation along with operation; dissolved oxygen DO in the Aerobic Pond 6 constantly rises; when rising to 2.0mg/L; current signal touches the shutdown driving switch of dissolved oxygen sensing transmitter 2; dissolved oxygen sensing transmitter 2 is by current signal control power-supply controller of electric 3; power-supply controller of electric 3 control blower fans 4 shut down; blower fan 4 fills air no longer for Aerobic Pond 6; prolongation along with stop time; dissolved oxygen DO in the waste water slowly descends; when dropping to 1.0mg/L; produce the start driving switch that current signal touches dissolved oxygen sensing transmitter 2, open thereby make power-supply controller of electric 3 control blower fan 4 once more.So finished according to the control fan switch time of the dissolved oxygen concentration in the waste water.Reduce to from 2.0mg/L in the time of 1.0mg/L because of dissolved oxygen DO in waste water, blower fan 4 is in closed condition, and the active sludge in the Aerobic Pond 6 is still at degradation of organic substances, so reached purpose of energy saving.
