Способ относится к технологии получения коагулянта, который может быть использован при очистке промышленных и хозяйственно-питьевых вод. Коагулянт на основе смешанных основных солей алюминия получают при обработке гидроксида алюминия смесью соляной и серной кислот в присутствии фтористоводородной кислоты или ее солей при следующем соотношении компонентов, мол.:
(Cl-1+SO -2 4 )/Al2O3=2÷5;
SO -2 4 /Cl-= 0,16÷0,21;
F-1/Cl-1 = 0,05 oC 0,07,
при этом используют водный раствор соляной и серной кислот при следующем соотношении, мол.:
(HCl + H2SO4)/H2O =0,07 - 0,1.
The method relates to the technology of coagulant, which can be used in the purification of industrial and drinking water. Coagulant based on mixed basic aluminum salts is obtained by treating aluminum hydroxide with a mixture of hydrochloric and sulfuric acids in the presence of hydrofluoric acid or its salts in the following ratio of components, mol:
(Cl -1 + SO -2 four ) / Al 2 O 3 = 2 ÷ 5;
SO -2 four / Cl - = 0.16 ÷ 0.21;
F -1 / Cl -1 = 0.05 o C 0.07,
an aqueous solution of hydrochloric and sulfuric acids is used in the following ratio, mol:
(HCl + H 2 SO 4 ) / H 2 O = 0.07 - 0.1.
Процесс проводят при нагревании и перемешивании с последующим отделением раствора коагулянта от непрореагированного гидроксида алюминия. Использование изобретения позволяет утилизировать отходы и вторичные продукты производств органического синтеза, не снижая потребительских качеств коагулянта. The process is carried out by heating and stirring, followed by separation of the coagulant solution from unreacted aluminum hydroxide. The use of the invention allows to dispose of waste and secondary products of the production of organic synthesis, without reducing the consumer qualities of coagulant.
