1. Equipment Insulation & Protection
- Insulate critical components (dissolved air tanks, pumps, pipelines, valves) using insulation materials
- Install insulation boxes for exposed instruments and control systems
- Regularly check insulation layer integrity and promptly repair damage
- Remove snow and ice from equipment surfaces to prevent low-temperature corrosion
2. Water Quality Parameter Control
- Adjust flocculant and coagulant dosages appropriately for winter conditions
- Extend reagent mixing and reaction time for sufficient coagulation
- Monitor influent temperature; implement heating if water temperature is too low
- Optimize effluent circulation to maintain stable tank temperature
3. Dissolved Gas System Maintenance
- Regularly clean impurities and scale from water release devices
- Adjust dissolved air tank pressure to compensate for low-temperature efficiency loss
- Drain accumulated water from tanks and pipelines during shutdowns
- Check pipeline patency thoroughly before system restart
4. Daily Inspection & Management
- Increase inspection frequency; check for abnormal noises or overheating
- Monitor electrical system insulation; clean condensation from wiring
- Maintain accurate operational data records; adjust strategies based on parameters
- Prepare emergency supplies and response plans for freezing and failures
Winter Operation Summary
Regular maintenance and monitoring during winter months are essential for system stability.
Focus on insulation, temperature control, and preventive measures to avoid freezing-related damage.
All personnel should be trained on winter-specific procedures and emergency protocols.
