摘要： [PROBLEM] To recover phosphorus accumulated in a sewage-treatment plant or the like at a low cost in such a manner as to facilitate the utilization of the thus recovered phosphorus. To efficiently utilize the recovered phosphorus as a fertilizer.
[SOLUTION] Phosphorus in waste water, which is a phosphorus source, is adsorbed by a phosphorus recovery material formed of an amorphous calcium silicate-based material and thus recovered. After adding the phosphorus recovery material to the waste water that is a phosphorus source, it is preferred to adjust the pH value of the waste water to 7.0 or higher. Also, it is preferred that the waste water that is a phosphorus source is decarbonated by reducing the pH value thereof to 6.0 or lower and then the phosphorus recovery material is added. As the phosphorus recovery material, an aggregate of an amorphous calcium silicate hydrate and Ca(OH) 2 and having a Ca/Si molar ratio of 0.8-20 inclusive is preferred. The aggregate may be obtained by solid-liquid separation and drying. Alternatively, a slurry or paste containing the aggregate may be used. The recovered phosphorus recovery material can be used as a fertilizer.

摘要： To reduce cost of chemical by reducing quantity of foaming agent used when removing unburned carbon in fly ash with wet floatation and to prevent decrease in activity index of the fly ash.
MEANS FOR SOLUTION
In wet decarbonization of fly ash comprising the steps of: adding water to fly ash to generate slurry; adding hydrophobizing agent and foaming agent to the slurry and agitating them to generate bubbles; and adhering unburned carbon in the fly ash to the bubbles to float them to remove the unburned carbon in the fly ash, when sedimentation component at wet floatation separation is solid-liquid separated and liquid phase obtained by solid-liquid separation is reused for another floatation separation for new fly ash, the quantity of foaming agent added to the slurry is adjusted such that concentration of the foaming agent in liquid phase is in a predetermined range. When adjusting the concentration of the foaming agent in the liquid phase, it is possible to measure COD concentration in the liquid phase and adjust the quantity of the foaming agent added to the slurry in such a manner that the COD concentration is in a predetermined range.
