AI Technical Summary
In SBR biological systems, manual control of parameters such as influent flow rate, aeration time, mixing time, and sludge concentration can lead to unstable system operation, increase labor intensity, and may result in unqualified effluent indicators or even system shutdown.
An automatic control unit combined with sensors and actuators is used to achieve automated control of the SBR biological treatment tank. This includes sensors for pH, dissolved oxygen, liquid level, and sludge concentration. Through the linkage of the controller with valves, pumps, blowers, etc., parameters such as aeration, stirring, and influent are precisely adjusted.
It has achieved continuous and stable operation of the SBR biological system, improved wastewater treatment efficiency, reduced the labor intensity of operators, ensured stable effluent quality, and has significant economic and social benefits.
