Method for manufacturing a porous composite for treating contaminated water using waste sludge, a porous composite manufactured therefrom

摘要

The present invention relates to a method of manufacturing a porous composite for treating contaminated water using waste sludge, and to a porous composite manufactured therefrom. The present invention, by mixing the waste sludge, zero iron (Fe ⁰ ), an alginic acid binder and an admixture, so that the waste sludge, zero iron and an admixture adhere to the alginic acid binder, a mixture preparation step; The mixture is heat-treated to form a three-dimensional support in which alginic acid is formed with a plurality of pores, but the attached waste sludge, zero-valent iron, and admixture form a complex, including: an alginic acid-zero iron-waste sludge-admixture composite manufacturing step; When the complex comes into contact with contaminated water containing contaminants, the contaminants donate electrons from the zero-valent iron and are adsorbed to the pores of the complex as they are reduced and decomposed to remove contaminants to improve the contaminated water permeability and contaminant reactivity. A method of manufacturing a porous composite for treating contaminated water using waste sludge, characterized in that it has, and a porous composite produced therefrom, as a technical point.
