Filtering material for removing iron and manganese

The invention relates to a filtering material for removing iron and manganese from water, and a manufacturing method thereof. The invention is characterized in that the filtering material is made by using irregular polyhedral filtration particles, which are obtained by crushing and screening building ceramic particles and of which the surfaces have pores, and by making an adhesive layer containing ferric oxide and manganese on the surfaces of the filtration particles by using a chemical or coating method. The filtering material has a large specific surface ratio, a small specific gravity and good physical and chemical properties and can be manufactured by a simple and convenient method. The water iron and manganese filtration effect of the filtering material is better than that of natural manganese sand, so the filtering material has a promising market application prospect.
