    摘要： Disclosed is a method for producing a cerium dioxide nanopowder by flame spray pyrolysis. The method comprises dissolving a cerium compound in an organic solvent to prepare a precursor solution, atomizing the precursor solution into microdroplets using an ultrasonic atomizer, transferring the microdroplets together with an argon gas as a carrier gas to a central portion of a high-temperature diffusion flame burner, subjecting the microdroplets to pyrolysis and oxidation in the central portion of the diffusion flame burner to produce a cerium dioxide nanopowder, and collecting the cerium dioxide nanopowder using a collector. According to the method, a cerium dioxide nanopowder can be continuously produced on a large scale by flame spray pyrolysis. In addition, the particle size and uniformity of the cerium dioxide nanopowder can be controlled by appropriately selecting the kind of the solvent and the concentration of the raw material. Furthermore, flame spray pyrolysis allows the cerium dioxide to have a fluorite crystal structure.

    摘要： The present invention provides a method for removing phosphorus and nitrogen contained in sewage or wastewater using iron ore wastewater. According to the method of the present invention, in which the phosphorus and nitrogen contained in sewage or wastewater are crystallized in the form of struvite using iron ore wastewater containing a large amount of Mg2+ produced in a process of upgrading low-grade iron ore and removed, it is possible to reduce the cost of Mg2+ and the cost of iron ore wastewater treatment, thereby earning economic profits. Moreover, it is possible to prevent water pollution by the removal of the phosphorus and nitrogen contained in sewage or wastewater. Furthermore, it is possible to use struvite crystals obtained as a by-product as a time-release compound fertilizer so as to reduce the amount of fertilizer used and the number of fertilizations, thereby reducing soil contamination.
