<p>A dephosphorization material disposed so that a material containing iron as a main component and a calcium compound material contact a phosphorus-containing aqueous solution, and provided with a water-permeable material around the material containing iron as a main component. A phosphorus component of sewage and river water can be removed easily by simply bringing this dephosphorization material into contact with such phosphorus-containing aqueous solutions, without employing any special solution control method. This dephosphorization material is capable of reducing the outflow of iron rust occurring due to the oxidation of iron during a dephosphorization of a phosphorus-containing aqueous solution, and the iron effluent can be eliminated by the action of the calcium compound material. Accordingly, this dephosphorization material can be applied pratically to sewage and river water. <IMAGE></p> |
