Inventor: KAWABATA KOICHI
IPC: C02F1/58
Filed: 2002-03-25
Abstract: <P>PROBLEM TO BE SOLVED: To use a phosphorus recovering material for a long period of time.  <P>SOLUTION: The method for recovering phosphorus is carried out by filling a reaction tank with a particulate phosphorus recovering material 1 essentially comprising calcium silicate hydrate, passing and retaining raw water containing phosphorus in the tank and injecting calcium ions 2 to the reaction tank to adsorb phosphorus in the raw water to the surface of the phosphorus recovering material to recover phosphorus. At least a part of the particulate phosphorus recovering material 1 which has adsorbed phosphorus to the surface in the reaction tank is drained to the outside of the tank, and at least a part of the recovering material drained to the outside of the reaction tank is crushed in a crushing process so as to regenerate a phosphorus recovering material having a newly exposed surface for adsorption of phosphorus. The regenerated phosphorus recovering material is returned to the reaction tank. The above processes are repeated to recover phosphorus in the raw water.  <P>COPYRIGHT: (C)2003,JPO
