- Abstract:
- Actual operational data of an enhanced integrated process of a water plant treating different raw water from the Yangtze River, Luan River and their mixture in Tianjin in recent three years, especially the data of high temperature and high algae period, were compared and analyzed. The enhanced integrated process of pre-oxidation, pulse clarifying and chlorine disinfection could adapt to the change of raw water quality. The removal efficiencies of turbidity and CODMn in three raw waters were more than 94.90% and 64%, respectively. The lowest turbidity and CODMn in the effluent were 0.13 NTU and 0.29 mg/L, respectively, and algae were not detected. Disinfection by-products indexes such as THMs, HAAs, formaldehyde and bromate were all far below the maximum contaminant levels of national standard limits, indicating that the process can ensure the safety of the effluent water quality.
