Изобретение относитс к способам обработки минерализованных вод и может быть использовано в химической промышленности.The invention relates to methods for treating saline water and can be used in the chemical industry.
Цель изобретени - снижение содержани сульфатионов.The purpose of the invention is to reduce the content of sulfations.
Пример 1. Сточную воду с содержанием сульфат-ионов 3 г-эвк/л обрабатывают известью в количестве 3 г-экв/л, перемешивают в течение 1 ч и отдел ют осадок. Затем ввод т различные количества карбо- чата кальци и провод т насышение воды углекислым газом при повышенном давлении, после чего повторно отдел ют осадок.Example 1. Sewage water containing 3 g eV / l sulfate ions is treated with lime in an amount of 3 g eq / l, stirred for 1 hour and the precipitate is separated. Then, various amounts of calcium carbonate are introduced and the water is raised with carbon dioxide at elevated pressure, after which the precipitate is again separated.
Дозы карбоната кальци , давление при обработке углекислым газом и остаточное содержание сульфат-ионов приведены в таблице .The doses of calcium carbonate, the pressure during carbon dioxide treatment and the residual content of sulfate ions are given in the table.

Пример 2. В сточные воды, аналогично описанным в примере 1, ввод т 39 мг-экв/л сульфата натри и известь в количестве, эквивалентном суммарному содержанию суль- содержание 20 фат-ионов, перемешивают и отдел ют осадок. л.Затем обрабатывают углекислым газом доExample 2. In the wastewater, similarly to that described in Example 1, 39 mg-eq / l of sodium sulfate are added and lime in an amount equivalent to the total content of sulfate 20 fat ions, is stirred and the precipitate is separated. l.Then treated with carbon dioxide to
рН 9,6. Остаточное содержание сульфат- ионов составл ет 39 мг-экв/л.pH 9.6. The residual sulfate ion content is 39 mEq / L.
Из примеров 1 и 2 следует, что введение 25 карбоната кальци и углекислого газа при повышенном давлении обеспечивает более глубокую степень очистки сточных вод от сульфат-ионов.From examples 1 and 2 it follows that the introduction of 25 calcium carbonate and carbon dioxide at elevated pressure provides a deeper degree of purification of wastewater from sulfate ions.
