    摘要： Provided are a method for preparing zinc oxide (ZnO) nanoparticles and a method for preparing ZnO nanofluid using the same. The method for preparing ZnO nanoparticles includes: a) heating deionized water; b) dissolving zinc (Zn) salt in the deionized water to prepare a precursor solution; c) adding solid alkali salt to the precursor solution to prepare a dispersion of ZnO nanoparticles; and d) separating the ZnO nanoparticles by solid-liquid separation and washing them with deionized water. Highly pure, crystalline ZnO nanoparticles with spherical shape and very narrow particle size distribution of 10 to 50 nm can be prepared quickly and at large scale and low cost using inexpensive materials via a stable low-temperature process, without using a dispersant. The associated low-temperature, normal-pressure process produces few harmful materials and may be easily employed for production of ZnO nanoparticles.

    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.
