english Setting an Appropriate Liquid Level Reference
- Determine reference range based on equipment's actual processing requirements and structural characteristics
- Excessively high levels cause scum overflow, contaminating treated water
- Excessively low levels reduce contact area between air bubbles and wastewater
- Refer to equipment manual parameters and adjust based on daily performance
- Gradually adjust to optimal range for stable operation
Utilize an Automatic Control System
- Automatic level control enables precise, real-time liquid level management
- Liquid level sensors monitor changes and transmit data to control system
- System automatically adjusts outlet valve or inlet flow when levels exceed range
- Faster response than manual adjustments, avoiding human delay issues
- Ensures stable equipment operation with minimal fluctuations
Dynamic Adjustment According to Processing Load
- Liquid level control must adapt to changing processing loads
- When pollutant concentration increases, lower level to accommodate scum
- When load decreases, raise level to ensure adequate bubble-wastewater contact
- Base adjustments on influent water quality monitoring and scum formation
- Prevent level abnormalities caused by load fluctuations
Regular Inspection and Component Calibration
- Regular inspection and calibration ensure effective control
- Check liquid level sensor sensitivity to prevent inaccurate monitoring
- Inspect outlet valve and inlet regulating valve operation
- Ensure valves open/close smoothly without sticking or leaking
- Calibrate automatic control system parameters regularly
- Prevent control failure due to parameter deviations
