摘　　要：山东省某市首座地表水厂设计总规模为6×10^(4)m^(3)/d,一期工程规模4×10^(4)m^(3)/d,采用预臭氧/机械混合/网格絮凝/斜管沉淀/主臭氧/活性炭滤池/砂滤池/次氯酸钠消毒工艺,工艺流程长,用地紧张,且厂区被市政道路分隔,给工艺布置和人员通行带来困难。设计中采用集约化布置,将全部净水处理设施集中布置在综合净水间内,将排泥水处理设施集中布置在排泥水处理车间内,既满足了工艺处理要求,又节约了占地,也方便了管理。通过地下通道连接水厂不同区域,既满足了人员和小型工/器具通行的需求,又避免了频繁穿行市政道路的麻烦。运行实践表明,该水厂处理效果优良,出水106项水质指标全部达到《生活饮用水卫生标准》(GB 5749-2006)要求。The total design treatment capacity of the first surface water plant in a city of Shandong Province is 6 × 10^(4)m^(3)/d,and the treatment capacity of the first phase is 4 ×10^(4)m^(3)/d. The treatment process consists of pre-ozonation,mechanical mixing,grid flocculation,inclined tube sedimentation,ozonation,activated carbon filter,sand filter and NaClO disinfection. The process has several problems such as long process,few available footprints,incomplete plant area divided by municipal roads,which bring difficulties to process layout and passage of personnel. Therefore,intensive layout was adopted in the design. All the water treatment facilities were centralized in the comprehensive water purification room,and the sludge treatment facilities were centralized in the sludge treatment workshop. The design not only met the process treatment requirements,but also reduced the footprint and facilitated the management. Connecting different areas of the water plant through the underground passage not only met the needs of personnel and small tools/appliances passage,but also avoided the trouble of frequent passing through municipal roads. The operation practice showed that the treatment performance of the water plant was good,and all 106 water quality indices of the effluent met the requirements of Standards for Drinking Water Quality( GB 5749-2006).
