【 摘 要 】

This study analysed the water quality of the mixed raw water of Yellow River Water(YW) and South-to-North Water Diversion Water (SNW) in the proportion of 2:1, 1:1, 1:2. According to the actual operation condition of most water treatment plant in Zheng Zhou, PAC was used as coagulant and activated silica acid as coagulant aid for enhanced coagulation. Finally, the removal efficiency of turbidity, UV254, NH3-N for different raw water was gave. The optimum coagulant and coagulant aid (activated silica acid) dose of enhanced coagulation were determined. The results of this study would provide guidelines to the optimization operation of the local water treatment plants which used the mixed raw water of YW and SNW.
