Summary:PROBLEM TO BE SOLVED: To provide a solid phosphorus removing agent wherein the agent is agglomerated from an iron salt or an aluminum salt (both are very water-soluble) which reacts with a phosphate ion to solidify the phosphate ion, and also controlled-releasability (low in water dissolvability) is given to the agglomerated material, and to provide a production method of the solid phosphorus removing agent, a dissolving method of the solid phosphorus removing agent in water, a dissolving apparatus for the solid phosphorus removing agent and a waste-water purifying tank equipped with the dissolving apparatus. SOLUTION: The solid phosphorus removing agent contains the iron salt or the aluminum salt, a binder, and a vegetable oil as a liquid hydrophobic material. COPYRIGHT: (C)2011,JPO&INPIT
