Abstract

1. Способ очистки сточных вод от фтора путем обработки их известковым молоком до достижения pН 9-11, последующего разделения жидкой и твердой фаз отстаиванием и фильтрацией, отличающийся тем, что обработку ведут в присутствии кальцийсодержащего реагента, взятого в количестве, обеспечивающем массовое соотношение кальция и фтора (0,3-0,6):1 соответственно.2. Способ очистки сточных вод от фтора по п.1, отличающийся тем, что в качестве кальцийсодержащего реагента берут сульфат или хлорид кальция или фосфогипс - отход производства экстракционной фосфорной кислоты.1. A method of treating wastewater from fluorine by treating it with milk of lime until pH 9-11 is reached, subsequent separation of the liquid and solid phases by settling and filtration, characterized in that the treatment is carried out in the presence of a calcium-containing reagent, taken in an amount that provides a mass ratio of calcium and fluorine (0.3-0.6): 1, respectively. 2. The method of wastewater treatment from fluorine according to claim 1, characterized in that as a calcium-containing reagent take sulfate or calcium chloride or phosphogypsum is a waste product of the extraction of phosphoric acid.
