摘　　要：介绍了磁絮凝-膜过滤与药剂软化组合工艺降低原水硬度的原理。研究了石灰投加量、絮凝剂投加量、磁粉投加量以及沉淀时间等因素对试验效果的影响。试验结果表明:组合工艺能有效降低水的硬度,且出水水质、水量稳定;膜通量衰减较慢且清洗后通量恢复情况良好。A chemical softening process combined with magnatic flocculation and membrane filtration was developed to reduce raw water hardness. The influence of different factors such as dosage of lime,coagulant and magnetic seed,settling time and other factors on experiment effect were systematically studied. The results show that the combined process can reduce water hardness with stability of water quality and water quantity,and the flux decaying of membrane is slow and keeps the membrane in normal condition after cleaning.
