摘　　要：为满足新建2 500 m3高炉工业用水要求,将1#钟罩式脉冲澄清池从工艺、土建、电气等各方面着手进行二次改造。改造流程采用管道静态混合器-折板絮凝池-斜管沉淀池工艺组合方式。改造后设计产水量恢复到2 500 m3/h,混凝沉淀池出水SS的质量浓度低于20 mg/L,浊度低于10 NTU,出水水质、水量能够满足厂内新增设备后生产用水要求。For the purpose of meeting the requirements of industrial water for 2 500 m3 blast furnace, the second reconstruction of 1# bell-shape pulse clarifier was carried out from aspects of process, civil construction, electric system, and so on. The reconstruction engineering adopted a combination process of pipe static mixer- folded-plate flocculating tank-inclined-tube sedimentation tank. Through the reconstruction, the design water yield recovered to 2 500 m3/h, the mass concentration of the SS and turbidity in the effluent water from coagula- tion sedimentation tank were lower than 20 mg/L and 10 quantity of the effluent water could meet the requirement newly added equipments. NTU respectively, which indicated that, the quality and of the production water supply system of the plant with newly added equipments.
