The intelligent laboratory wastewater treatment system achieves full process intelligent management from wastewater collection to standard discharge through integrated automation control technology. Its core strategy covers the following aspects:
1、 Automated linkage control of multi-level processing units
The system adopts PLC programmable logic controller to accurately control core processing units such as coagulation sedimentation, ozone oxidation, catalytic microelectrolysis, membrane filtration, etc. For example, when the water level in the collection tank reaches the set value, the system automatically starts the water pump to pump the wastewater into the coagulation tank, and automatically adjusts the acidity and alkalinity based on the feedback data from the pH sensor. Then, heavy metal capture agents and coagulant aids are added according to the preset ratio. During the processing, the operating status of each unit (such as water tank level, water pump pressure, instrument readings) is displayed in real-time on the human-machine interface, supporting seamless switching between automatic and manual modes to ensure operational flexibility.
2、 AI intelligent regulation and dynamic optimization
Introducing AI algorithms to analyze historical data and real-time monitoring data, achieving dynamic adjustment of processing parameters. For example, when fluctuations in wastewater composition are detected, the system can automatically optimize the dosage of chemicals, aeration rate, and reaction time to ensure stable treatment effects. A laboratory application case shows that AI regulation reduces drug consumption by 15%, improves processing efficiency by 20%, and identifies equipment abnormalities in advance through fault prediction function, reducing downtime risk.
3、 Real time monitoring and security protection throughout the entire process
The system is equipped with a multi parameter online monitoring instrument, which continuously detects indicators such as COD, BOD, and heavy metal ions. When the data is abnormal, it automatically triggers an alarm and starts the reflux treatment program. In addition, automatic protection mechanisms for abnormal states such as water, power, and overload are set up to prevent equipment damage or secondary pollution through interlocking control. For example, when the pressure of the membrane filtration device exceeds the limit, the system automatically pauses the water inlet and starts the backwash program to extend the service life of the membrane components.
4、 Data driven operation and maintenance management
Through the automated report generation function, the system records key data such as processing volume, energy consumption, and medication consumption on a daily basis, and supports remote monitoring and historical data tracing. Management personnel can optimize operational strategies based on data analysis, such as adjusting scheduled on/off times to match laboratory wastewater discharge patterns, further reducing operating costs.
