Method for manufacturing magnetic iron oxide and apparatus for removal and recovery of phosphate using the same

摘要

The present invention relates to a method for producing magnetic iron powder and a method for removing and recovering phosphate from the magnetic iron powder. More particularly, the present invention relates to a method for easily and easily producing a magnetic iron powder having an excellent ability to adsorb and desorb phosphate, And more particularly, to an improved phosphate removal and recovery apparatus. INDUSTRIAL APPLICABILITY According to the present invention, it is possible to easily produce a magnetic iron powder which is excellent in the adsorption and desorption ability of phosphate and can be reused and is useful in actual processes. In addition, when the magnetic iron powder is used in the apparatus for removing and recovering phosphate according to the present invention, high-purity phosphate can be secured and the recovered magnetic iron powder can be used repeatedly.
