| titleOfInvention | How to remove phosphorus in water |
| abstract | (57) [Abstract] [Purpose] To provide a method for removing phosphorus in water, which has a high rate of phosphorus removal and is efficient, and which does not generate sludge that is difficult to concentrate and difficult to dehydrate. [Structure] Particles of ferric hydroxide and / or aluminum hydroxide are generated in advance, and the particles are dispersed to prepare a slurry whose sedimentation concentration is controllable, and the slurry is added to raw water containing phosphorus. After that, raw water is led to a biological treatment process, the outflow water of the biological treatment process is subjected to solid-liquid separation, and the separated water is treated water to remove phosphorus in water. Particles can be produced to prepare a slurry whose sedimentation concentration is controllable by adding an alkaline agent to an acidic solution of an iron salt or an aluminum salt to neutralize the solution, and ferric hydroxide and / or Alternatively, a precipitate of aluminum hydroxide is produced. |
