磁种絮凝技术在水处理中的研究进展

Research Progress on Magnetic Seeds Flocculating Technology in Water Treatment

综观近几年磁种絮凝技术在水处理中的研究,着重介绍了常用磁种的分类,主要包括:天然磁种、人工磁种、生物磁种和磁流体;根据磁种分类,概述了4种常用磁种絮凝技术的研究进展,同时,对磁种絮凝技术在水处理中的今后研究趋势进行了探讨,并得出了一些结论:磁种絮凝技术在水处理过程中:(1)方法简单易行、处理效果明显且成本相对较低;(2)磁种的选择至关重要;(3)药剂的选取不同会使沉降最终结果差异很大。

Throughout the research of magnetic seeds flocculating technology in water treatment in recent years, the classification of magnetic seeds was emphatically introduced, including the natural, the artificial, the biological and the magnetic fluids. According to the classification of magnetic seeds, the current research progress on the four kinds of natural magnetic seeds was summarized and the trend of this technology in water treatment was discussed. Some conclusions were drawn： in the process of magnetic seeds flocculating technology in water treatment, the method was simple, the effect was good and the cost was low, the choice of the classification of magnetic seeds was essential, with the difference of the additives, the difference of the results was very obvious.
