摘　　要：通过模拟混凝工艺,考察了单独投加蒙脱石粉溶液、阴离子聚丙烯酰胺溶液以及两者联用时极低浊度水(<5 NTU)的处理效果。结果表明:单独投加蒙脱石粉溶液以及阴离子聚丙烯酰胺溶液对去除水体浊度、氨氮效果不佳,两者联用能够有效降低极低浊度水的浊度和氨氮质量浓度,可作为处理极低浊度水的强化混凝工艺,能够低成本提高原工艺的混凝沉淀效果以及给水污泥的沉降性能。By simulating the coagulation process,the treatment effects of extremely low turbidity water by separate dosing montmorillonite powder solution and anionic polyacrylamide solution and the combination were investigated.The results show that the separate dosing has poor effect on removing water turbidity and ammonia nitrogen.The combination can effectively reduce the turbidity and ammonia nitrogen mass concentration,which can be the enhanced coagulation process of treatment of extremely low turbidity water.It can reduce cost and improve the coagulation sedimentation effect of the original process and the sedimentation performance of the feedwater sludge.
