Abstract
1. Способ очистки природных вод от железа, включающий предварительное озонирование с последующей фильтрацией взвешенной фазы через фильтр, отличающийся тем, что озонирование ведут в присутствии катализатора, а последующее отделение образовавшейся взвешенной фазы трехвалентного гидроксида железа осуществляют путем фильтрации через зернистую загрузку. ! 2. Способ по п.1, отличающийся тем, что в качестве катализатора используют пероксид водорода в концентрации 2,0-3,0 мг/л. ! 3. Способ по п.1, отличающийся тем, что в качестве зернистой загрузки используется мраморная крошка фракции 1-3 мм, активированная трехвалентным гидроксидом железа. ! 4. Способ по любому из пп.1-3, отличающийся тем, что озонирование применяют в качестве кратковременной инициирующей стадии, а полное окисление завершается в объеме фильтрующей загрузки.1. A method of purifying natural waters from iron, including preliminary ozonation followed by filtration of the suspended phase through a filter, characterized in that the ozonation is carried out in the presence of a catalyst, and the subsequent separation of the resulting suspended phase of ferric iron hydroxide is carried out by filtration through a granular charge. ! 2. The method according to claim 1, characterized in that the catalyst used is hydrogen peroxide in a concentration of 2.0-3.0 mg / L. ! 3. The method according to claim 1, characterized in that the granular charge is used marble chips of a fraction of 1-3 mm, activated by ferric iron hydroxide. ! 4. The method according to any one of claims 1 to 3, characterized in that ozonation is used as a short-term initiating stage, and complete oxidation is completed in the volume of the filter charge.
