Изобретение относитс к способам очистки сточных вод от металлов и, может быть использовано в металлургической , машиностроительной, хими- ческой и горно-рудной промышлен- ност х.The invention relates to methods for the purification of waste water from metals and can be used in the metallurgical, engineering, chemical and mining industries.
Целью изобретени вл етс обеспечение возможности очистки высококонцентрированных сточных вод при сохра- нении высокой степени очистки.The aim of the invention is to enable the treatment of highly concentrated wastewater while maintaining a high degree of purification.
Очистку ведут при рН 5,0-7,5. Область рН в данном случае ограничиваетс физиологическими значени ми рН дл дрожжей Saccharorayces carlsber- gens is, a также образованием осадков гидроокисей металлов при щелочных значени х рН.Purification is carried out at a pH of 5.0-7.5. The pH range in this case is limited by the physiological pH values for the yeast Saccharorayces carlsbergans is, as well as the formation of metal hydroxide precipitates at alkaline pH values.
Пример 1. В 200 мл раствора азотнокислой меди исходной концентра- дни ионов Си 3-60 мг/л ввод т 5 г измельченного фильтр-картона с сорбированным штаммом дрожжей Saa- charorayces carlsbergensis, идущего в отходы производства, перемепмвают и через 1,2,3,...,п ч отбирают пробы дл определени остаточной концентрации ионов меди в растворе. Параллельно став т контрольный опыт с чис- Tbw картоном, не использованным в производстве.Example 1. In 200 ml of a solution of copper nitrate, of the initial concentration of Cu ions 3–60 mg / l, 5 g of crushed filter board with the adsorbed Saa charorayces carlsbergensis yeast strain, which was discarded, are mixed and, after 1.2, 3, ..., n and h samples are taken to determine the residual concentration of copper ions in the solution. At the same time, control experience was put on with a Tbw cardboard not used in production.
П р и м е р 2. Способ осуществл ют в услови х примера 1, но готов т раствор азотнокислого серебра с исходной концентрацией ионов Ag 40- 195 мг/л.EXAMPLE 2 The method is carried out under the conditions of Example 1, but a silver nitrate solution is prepared with an initial concentration of Ag ions of 40- 195 mg / l.
П р и м е р 3. Способ осуществл ют в услови х примера 1, но готов т раствор сернокислого хрома с исходной концентрацией ионов Сг 10 мг/л.EXAMPLE 3. The method is carried out under the conditions of Example 1, but a solution of chromium sulfate with an initial concentration of Cr ions of 10 mg / l is prepared.
Содержание металлов до и после очистки, а также данные по сорбции ионов металлов фильтр-картоном до его использовани в производстве приведены в табл. 1.The content of metals before and after purification, as well as the data on the sorption of metal ions by the filter board before its use in production are given in Table. one.
Как видно из данных табл. 1, отходы производства значительно быстрее и полнее сорбируют ионы металлов, чем чистый картон.As can be seen from the data table. 1, production waste absorbs metal ions much faster and more completely than pure cardboard.
В табл. 2 представлены данные по степени и времени очистки от ионов меди, серебра дл известного и предлагаемого способов.In tab. 2 presents data on the degree and time of purification from copper, silver ions for the known and proposed methods.
Из табл. 2 следует, что предлагаемый способ позвол ет обеспечить возможность очистки высококонцентрированных сточных вод при сохранении высокой степени очистки, тогда как известный способ не обеспечивает очистку высококонцентрированных сточных вод с необходимой степенью очистки.From tab. 2 it follows that the proposed method allows for the treatment of highly concentrated wastewater while maintaining a high degree of purification, while the known method does not provide treatment of highly concentrated wastewater with the necessary degree of purification.
