摘要：PROBLEM TO BE SOLVED: To provide a dephosphorizing material excellent in dephosphorizing performance and capable of restraining the pH when water is made to pass initially from being excessively raised and stably removing a phosphate ion over a long period of time and to provide a method for removing phosphorus from the wastewater containing the phosphate ion by using the dephosphorizing material. SOLUTION: This dephosphorizing material consists of a hydrate of calcium silicate subjected to carbonation treatment. This dephosphorizing method comprises making the wastewater containing the phosphate ion pass through a column packed with the dephosphorizing material and subjecting the wastewater thus treated to aeration treatment.
