Description of drawings
The structural representation of the surface aeration energy-saving control device that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
As shown in Figure 1, the utility model provides a kind of surface aeration energy-saving control device, comprises controller, frequency transformer, is used for to the aerator of processed sewage aeration with for more than one water quality on-line monitoring instrument tables that gather processed sewage quality information; The input terminus of described controller is connected with various described water quality on-line monitoring instrument tables respectively, and the output terminal of described controller is connected with described aerator by described frequency transformer.Wherein, the water quality on-line monitoring instrument table includes but not limited to DO (Dissolved Oxygen, dissolved oxygen) detector and/or COD (Chemical Oxygen Demand, chemical oxygen demand (COD) or chemical oxygen demand) detector and/or MLSS (Mixed Liquid Suspended Solids, mixed liquor suspended solid, MLSS concentration) detector and/or pH sensor and/or water level sensor.At the concrete scene of arranging, controller can be connected with various described water quality on-line monitoring instrument tables respectively by fieldbus.In addition, also comprise warning device and display unit; Described warning device is connected with described controller.Warning device can be audible alarm unit, light warning device and SMS alarming device.Display unit is connected with described controller.
For realizing the purpose to the controller Long-distance Control, also comprise upper computer; Described controller is connected with described upper computer by network of communication.
The working process of the surface aeration energy-saving control device that the utility model provides is:
(1) in the process that sewage is processed, in sewage, various water quality on-line monitoring instrument tables is installed; Water quality on-line monitoring instrument table Real-time Collection sewage quality information, and the sewage quality information that collects is uploaded to controller; Wherein, sewage quality information comprises current DO value;
(2) controller receives various sewage quality information, and calculates by preset model, obtains current oxygen level and the actual oxygen requirement of processed sewage; Then produce control signal after contrasting current oxygen level and actual oxygen requirement;
In the utility model, preset model is to the abstract of Sewage Plant biological treatment principal character and reproduces in the controller, can be in time degree of declaring and suitably reply of various disturbances in the treating processes, to reach the effect of accurate control.Because Sewage Plant is an open system, can be subject to the impact of environment; In addition, the water inlet variation of Sewage Plant also has certain tendency, these factors all can cause the variation of sewage disposal aspect of model numerical value, controller is in time followed the tracks of these variations by various instrument, and preset model made corresponding adjustment, thereby can guarantee the accuracy of preset model.
(3) controller transmits control signal to frequency transformer, by the rotating speed of frequency transformer adjusting aerator, namely regulates the aeration quantity of aerator, thereby makes the oxygen level in the processed sewage trend towards actual oxygen requirement; (1)-(3) are carried out in circulation, realize the real-time fine adjustment to oxygen level in the processed sewage, reach the purpose of energy-saving and aerating.
By the control of controller, aerobic as benchmark take sewage is controlled to be target with the aerator rotating speed, realizes that DO accurately controls.In addition, can also realize intermittent aeration, limited aeration, normal aeration, dissolved oxygen distribution control etc.Help the user to realize the optimal control of processing parameter.
