摘　　要：针对高浊原水的特点,采用新型螺旋斜板一体化净水设备,考察了进水浊度和流量的变化及连续运行对该设备处理效能的影响。结果表明:当进水浊度为1 854～3 190 NTU时,一体化净水设备的最佳PAC投量为35～45 mg/L,出水浊度可达到《生活饮用水卫生标准》(GB5749—2006)的要求;当进水流量分别为192、240、288 m3/d时,滤后水浊度分别为0.16、0.16、0.36NTU,充分说明了一体化净水设备的抗冲击负荷能力强、处理效率高且运行稳定。Integrated water treatment equipment with spiral lamella was used to treat high turbidity water. The impact of influent turbidity and flow rate behavior and continuous operation on the equipment was investigated. The results showed that when the influent turbidity was 1 854 to 3 190 NTU, the optimal dosage of PAC was 35 to 45 mg/L, and the effluent turbidity reached the requirement of Standards for Drinking Water Quality （ GB 5749 - 2006）. When the influent flow rate was 192,240 and 288 m3/d, respectively, the effluent turbidity was 0.16, 0.16 and 0.36 NTU, respectively. The integrated water treatment equipment with spiral lamella has significant advantages such as strong shock load resistance, high removal efficiency and stable operation.
