Method and apparatus for treating manganese-containing water |
| abstract |
(57) [Problem] To provide a method and an apparatus for treating manganese-containing water capable of removing both soluble manganese and suspended manganese in water. SOLUTION: A fluidized bed reactor 1 having no support bed using manganese sand as a fluid medium, an inlet 14 for treated water 4 containing carbonate ions provided at the bottom of the reactor, and a treatment provided at an upper portion of the reactor. A manganese-containing water treatment apparatus for crystallizing and removing soluble manganese, which has a water outlet 9 and an alkali agent inlet 15 for adjusting the pH value of treated water in a fluidized bed, The fluidized bed reaction tower has a manganese sand fluidized bed 2 formed on the upper part of the fluidized bed 2 and a discharge pipe 11 for removing suspended substances in the suspended substance layer. The pH of the water to be treated is adjusted by injecting an alkali agent 15 to adjust the pH to 8 to 10, and the fluidized bed reaction tower adjusts the horizontal cross-sectional area of the suspended substance layer 12 portion. , It is larger than the horizontal cross-sectional area of the upper part of the manganese sand fluidized bed 2. |
