Effective assessment of wastewater treatment systems requires a comprehensive approach combining direct measurement, operational observation, comparative testing, and long-term monitoring.
Detect Key Pollutant Indicators
- Test core pollutant indicators in wastewater before and after treatment
- For suspended solids, use filtration method to collect solid particles from inlet and outlet water, then measure their mass to calculate removal rate
- For chemical oxygen demand, compare concentration of organic matter in inlet and outlet water
- For oil-containing wastewater, test oil content in both inlet and outlet samples
Observe Equipment Operation Status
- Monitor equipment's real-time operation status to indirectly assess treatment effect
- Check bubble generation: uniform, tiny bubbles that spread evenly suggest effective air dispersion
- Observe scum layer—thick, stable scum with clear separation indicates proper pollutant lifting
- Check water clarity at outlet: clear, transparent water means most impurities removed
Conduct Comparative Verification Tests
- Run parallel tests with same batch of wastewater
- Compare pollutant indicators, water clarity, and scum production between treated and untreated groups
- Adjust operating parameters and test repeatedly to identify optimal combinations
- Verify system maintains stable performance under optimal conditions
Monitor Long-Term Stability
- Regularly sample inlet and outlet water at fixed intervals
- Track changes in pollutant removal rates over time
- Stable removal rates indicate good long-term reliability
- Record operating data alongside test results to identify correlations
