摘要： PROBLEM TO BE SOLVED: To provide a method capable of efficiently and economically separating phosphorus from a composite oxide which contains the phosphorus and contains iron and calcium at a relatively high concentration.SOLUTION: A composite oxide containing 10 mass% or more of CaO, 10 mass% or more of total Fe, and 10 mass% or more of POis brought into contact with 1-normal or more alkali metal hydroxide aqueous solution, and phosphorus in the composite oxide is extracted into the alkali metal hydroxide aqueous solution. Alternatively, a composite oxide containing 30 mass% or more of CaO, 10 mass% or more of total Fe, and 1-5 mass% of POwith CaO/SiO(mass ratio) being 2 or greater is brought into contact with 5-normal or more alkali metal hydroxide aqueous solution, and phosphorus in the composite oxide is extracted into the alkali metal hydroxide aqueous solution. From the alkali metal hydroxide aqueous solution in which the phosphorus is extracted, phosphate ions are separated and the phosphorus is recovered.

摘要： PROBLEM TO BE SOLVED: To obtain treated water, from which fluorine is sufficiently removed, by stably and efficiently treating fluorine-containing wastewater with aluminum coexistence using a calcium fluoride method.
SOLUTION: A calcium compound is added to the fluorine-containing wastewater with aluminum coexistence while phosphoric ions are further added so that P/Al (molar ratio) becomes 1 or above and trivalent iron ions are further added so that an Fe/P (molar ratio) becomes 1 or more to subject insoluble matter to solid-liquid separation under a pH condition of 3.5-5.5. It is preferable to return the sludge subjected to solid-liquid separation to a reaction process. At this time, it is preferable that the calcium compound to be added to raw water is preliminarily mixed with the return sludge and the modified sludge is added to the raw water.

摘要： PROBLEM TO BE SOLVED: To quickly start up a water treatment apparatus in which raw water containing inorganic contaminant ions is reacted with an insolubilizing agent insolubilizing the inorganic contaminant ions to form insoluble matter, and to obtain sludge containing the insoluble matter and separated water by solid/liquid separation of the insoluble matter.
SOLUTION: In this starting-up method of the water treatment apparatus, prior to supply of the raw water to a reactor, the water treatment apparatus is filled with water, a compound containing inorganic contaminant ion sources is added to the reactor, and the insolubilizing agent is added to a mixing tank and water in the water treatment apparatus is circulated by operating a sludge returning means, and when the insoluble matter in a solid/liquid separating tank has reached a given amount, the addition of the compound is stopped, and supply of the raw water to the reactor is started.
