PHOSPHORUS RECOVERY MATERIAL, METHOD FOR PRODUCING PHOSPHORUS RECOVERY MATERIAL, AND PHOSPHORUS RECOVERY METHOD

摘要

The present invention provides a phosphorus recovery material which can recover phosphorus without requiring decarbonation treatment from water containing phosphorus and carbonic acid and has excellent fixing ability of phosphorus and sedimentation property after fixation of phosphorus, a method for producing the phosphorus recovery material and a phosphorus recovery method. The present invention provides, for example, a phosphorus recovery material including an amorphous calcium silicate hydrate single substance or a complex between amorphous calcium silicate hydrate and Ca(OH) 2 , produced by mixing a sodium silicate aqueous solution and lime without heating, wherein the hydrate single substance or the complex has a Ca/Si molar ratio of 0.8 to 1.5.
