- Abstract:
- Zhaoma water treatment plant in Xingtai City is a complementary project of Middle Route Project of South-to-North Water Transfer. The total design capacity is 35×104 m3/d. The capacity of the firststage project is 15×104 m3/d， and the capacity of the second-stage project is 20×104 m3/d. The project includes a new water treatment plant and corresponding distribution pipe network. Water source of the water treatment plant is from Danjiangkou reservoir with excellent water quality. Conventional treatment process of mechanical mixing tank，small grid reaction tank, double layer horizontal-flow sedimentation tank, V-type filter and ozone/GAC advanced treatment process， chlorine dioxide and ultraviolet ray multi-barrier disinfection are used to ensure the safety of water supply. The results showed that all the equipment and facilities ran stably, and the effluent quality of the water plant was better than the requirements of Standards for Drinking Water Quality (GB 5749-2006). The total investment of the project was 704.42 million yuan, and the operating cost was 0.76 yuan/m3 (excluding the water resources fee for the South-to-North Water Transfer).
