<p>PROBLEM TO BE SOLVED: To provide slurry for recovering phosphorus, which has a high dephosphorization effect when mixed with phosphorus-containing waste water to clean the waste water even if the phosphorus-containing waste water is not subjected to decarbonation treatment, which can allow a recovered product (a phosphorus-containing resource) being a solid having high phosphorus content to be obtained in large quantities in a short time and which can be prepared efficiently by a simple method.SOLUTION: The slurry for recovering phosphorus is prepared by using a powder and granular material, which contains calcium silicate hydrate as a main component and porous calcium silicate, water and an acid and contains the solid obtained by acidifying the powder and granular material by the acid.</p> |
