- Abstract:
- The project of Qinghe Qingyuan water purification plant in Hebei Province uses the Yangtze River raw water of South-to-North Water Diversion to replace the original fluorinecontaining groundwater source, which improves the local tap water quality and becomes the local popular project. The treatment capacity of Qingyuan water purification plant in the near future is 50 000 m3/d, 110 000 m3/d in the long term. According to the characteristics of raw water quality such as low temperature, low turbidity and high algae, the water purification plant adopted the process of preoxidation, mechanical mixing, mechanical flocculation tank, advection sedimentation tank, ozone contact tank, upward flow activated carbon adsorption tank, V filter, UV and NaClO disinfection. After completion, the effluent quality was much better than Standards for Drinking Water Quality (GB 5749-2006)， and the average turbidity of effluent was 0.20 NTU, CODMn was 1.29 mg/L.
