邢台市南水北调召马地表水厂工程设计

Design of Zhaoma Water Treatment Plant of South-to-North Water Transfer Project in Xingtai City

邢台市召马地表水厂是南水北调中线工程的配套项目,总工程规模为35×10^(4)m^(3)/d,其中一期规模为15×10^(4)m^(3)/d,预留二期规模为20×10^(4)m^(3)/d,包括新建地表水厂及相应配水管网。水源取自丹江口水库,水质优良,净水采用机械混合池→小网格反应池→双层平流沉淀池→Ⅴ型滤池常规处理+臭氧活性炭滤池深度处理组合工艺,出厂水采用二氧化氯与紫外线多级屏障消毒,确保供水水质安全。实际运行效果表明,各设备设施均运转稳定,水厂出水水质优于《生活饮用水卫生标准》(GB 5749—2006)的要求。工程总投资为70 442万元,经营成本为0.76元/m^(3)(不包括南水北调水资源费)。

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 35×10^(4) m^(3)/d.The capacity of the first-stage project is 15×10^(4) m^(3)/d,and the capacity of the second-stage project is 20×10^(4) m^(3)/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/m^(3)(excluding the water resources fee for the South-to-North Water Transfer).
