摘要
磁性絮聚分离技术是利用磁性颗粒(Fe3O4)与水中的污染物结合,再利用磁场对磁性颗粒的磁力作用将污染物与水分离。本研究利用特定磁化强度的Fe3O4加入到高浊度废水中,在外加磁场的作用下,藉由外加磁场所产生之磁力提供额外的吸引力,以提升混凝沉淀程序去除浊度的效率,并研究磁性颗粒添加量、水质参数变换及外加磁场等操作条件对高浊度原水处理效果的影响,期望能找到处理高浊度废水的有限参数组合,为磁性颗粒在高浊度废水处理中的运行提供理论支持。
The magnetic flocculation separation technology is the combination of the magnetic particle （tri-iron tetroxide） with the pollutants in water to separate the pollutants from water by means of the magnetic effect of the magnetic field on the magnetic particles. In this research, with the extra attractive force of the applied magnetic field, the specific magnetization intensity tri-iron tetroxide is added to the high turbidity waste water to improve the removal efficiency of turbidity. We also study the effect under different conditions of the magnetic particles, water quality parameters and applied magnetic field on the high turbidity water. Through the research, we expect to work out the optimization parameters combination of the purification of the high turbidity waste water and offer the theoretical support to the operation feasibility of the magnetic particles in the purification of the high turbidity waste water.
