IPC: C02F1/58
Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To provide a treating method for fluorine-contg. water whereby the water content of the resultant calcium fluoride cake is reduced; the effective application of this cake is broadened; and the space occupied by a treating apparatus is reduced by conducting solid-liquid separation by a means selected from among filtration, centrifugal separation, concentration by evaporation, and floatation. SOLUTION: A calcium salt 35 (e.g. calcium hydroxide) is added to fluorine-contg. wastewater in a reaction vessel 26 to form calcium fluoride. After the pH of the wastewater is adjusted in a pH-adjusting vessel 27, the wastewater is subjected to solid-liquid separation in a cocentration apparatus 28. As the concentration apparatus 28, one which can carry out the solid-liquid separation of the calcium fluoride-contg. wastewater discharged from the reaction vessel 26 and which is based on filtration, centrifugal separation, concentration by evaporation, or floatation is used. Since a concentration means based on filtration, centrifugal separation, concentration by evaporation, or floatation makes the separation possible without allowing crystals to grow, the addition of a flocculant is not necessary.  An example of a solid-liquid separation means based on filtration is a method based on membrane separation; in this case, an ultrafiltration membrane, a micro-filtration membrane, filter cloth, etc., are used as a filtration membrane.
