Water treatment plant raw water is from the Yellow River, the south of the city of Baotou along the Yellow River,and the Yellow River water volume was in rich,was the main source of water for industrial and agricultural production in Baotou City. There are some indicators exceeded chemical oxygen demand, total iron, ammonia, and Kung, coliform bacteria and total phosphorus. Select the appropriate treatment process to water treatment is very important, traditional water treatment processes was coagulation, flocculation, sedimentation, filtration and disinfection. According to the water quality characteristics of this design pre-sedimentation clear turbidity, then by coagulation, flocculation and sedimentation, and filtration.To remove organic matter and mercury add an activated carbon filter after the filterand then disinfected, and finally to meet the service head for to the water supply pipe network.
