磁分离技术在固-液污染物治理中的应用

In this paper, the applications of magnetic separation (MS) technology in solid separation and sewage treatment are reviewed. Owing to the simple operation, broad application scope, and little secondary pollution output, MS techniques have been more and more applied in solid and liquid pollutants treatment. Environmental MS techniques develop rapidly at home and abroad in recent years. Important achievements have been made in the applied research fields of new MS, including eddy current separation, superconducting magnetic separation, and magnetophoresis separation, which greatly improves the effect of the waste separation. On the other hand, complex pollutant problems put forward higher requirements for magnetic separation techniques, which promote the technical progress. On the basis of the review on the key MS techniques, the development direction of magnetic separation is discussed. This review can provide reference for the development of MS technology, as well as for its application in waste treatment and resoure circulation industry.
