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。
Aiming at the characteristics of high turbidity raw water, a new spiral inclined plate integrated water purification equipment was adopted to investigate the influence of the change of turbidity and flow of water and the continuous operation on the treatment efficiency of this equipment. The results show that when the turbidity of inflow water is 1 854 ~ 3 190 NTU, the optimum PAC dosage of integrated water purification equipment is 35 ~ 45 mg / L, the effluent turbidity can reach the standard of sanitary drinking water (GB5749 -2006). When the influent flow rates were 192, 240 and 288 m3 / d, respectively, the turbidity of the filtered water was 0.16, 0.16 and 0.36 NTU respectively, which fully demonstrated that the integrated water purification equipment has strong impact load capacity , Processing efficiency and stable operation.
