The super-magnetic separation technology has the advantages of good water discharge effect, fast treatment speed, simple process flow, etc. In recent years, it has been rapidly promoted in the field of water treatment and its application scope has gradually increased. The core of the technology includes the selection of super-magnetic particles, super-magnetic separation and magnetic seed recovery equipment. This paper summarized the application fields and effects of the super-magnetic separation technology, reviewed the development of magnetic seeds, point out that the development of high performance magnetic particles is one of the future research directions, and also introduces the research results on the preparation of magnetic ferroferric oxide particles by co-precipitation method.
