Abstract
Description
Изобретение относится к технологии очистки воды, в частности к очистке сточных вод от ионов меди сорбцией.The invention relates to water treatment technology, in particular to the treatment of wastewater from copper ions by sorption.
Известен способ очистки сточных вод от тяжелых металлов и органических веществ (SU 1560483, CO2F 1/28, Б.И. N 16, 1990 г.), включающий обработку золой и отделение осадка осаждением, в котором сточные воды последовательно обрабатывают сначала золой, содержащей оксид кальция 30-50%, до рН=8,75-9,25, а затем золой, содержащей оксид кальция 3-5%, до рН=6,5.A known method of treating wastewater from heavy metals and organic substances (SU 1560483, CO2F 1/28, B.I. N 16, 1990), comprising treating with ash and separating the precipitate by sedimentation, in which the wastewater is first treated with ash containing calcium oxide 30-50%, up to pH = 8.75-9.25, and then ash containing calcium oxide 3-5%, up to pH = 6.5.
Недостатками данного способа является большой расход сорбента в связи с малой сорбционной емкостью золы по отношению к меди, низкая скорость фильтрации и сложность технологического процесса.The disadvantages of this method is the high consumption of the sorbent in connection with the low sorption capacity of the ash in relation to copper, low filtration rate and the complexity of the process.
Известен способ очистки сточных вод от ионов меди (SU 1495308, C02F 1/62 Б.И. N 27, 1989), в котором воду обрабатывают щелочным раствором и активированным углем с последующим выдерживанием смеси при температуре 50-55 градусов в течение 30 минут и отделением осадка.A known method of wastewater treatment from copper ions (SU 1495308, C02F 1/62 B.I. N 27, 1989), in which the water is treated with an alkaline solution and activated carbon, followed by maintaining the mixture at a temperature of 50-55 degrees for 30 minutes and separation of sediment.
Недостатками данного способа являются большой расход сорбента, низкая скорость фильтрации и дополнительные затраты на технологические операции по подогреву и отстаиванию раствора.The disadvantages of this method are the high consumption of the sorbent, low filtration rate and additional costs for technological operations for heating and settling the solution.
Наиболее близким по технической сущности к заявляемому техническому решению является выбранный за прототип способ очистки сточных вод от ионов меди, который основан на фильтрации через слой сорбента толщиной слоя 0,075-0,09 м, а в качестве сорбента используется отходы измельченного пеногипса (RU №2360868, C02F 1/28, BO1J 20/28, 26.05.2008).The closest in technical essence to the claimed technical solution is the selected prototype method of wastewater treatment from copper ions, which is based on filtering through a sorbent layer with a layer thickness of 0.075-0.09 m, and as a sorbent the waste of ground foam gypsum is used (RU No. 2360868, C02F 1/28, BO1J 20/28, 05.26.2008).
Недостатком данного способа является большой расход сорбента и необходимость измельчения сорбента перед фильтрацией.The disadvantage of this method is the high consumption of the sorbent and the need for grinding the sorbent before filtration.
Задачей, на решение которой направлено заявляемое изобретение, является уменьшение расхода сорбента без фильтрации через измельченный сорбент.The problem to which the invention is directed, is to reduce the consumption of the sorbent without filtering through crushed sorbent.
Поставленная задача в предлагаемом решении достигается тем, что в способе очистки сточных вод от ионов тяжелых металлов, включающем обработку сорбентом, путем отстаивания в течение 3-х часов в присутствии готовых гипсовых изделий с размерами 20×20×20 мм, полученных при затворении порошкообразного гипса дистиллированной водой, с добавлением карбоната натрия Na2CO3 в соотношении 15% от массы гипса.The problem in the proposed solution is achieved by the fact that in the method of wastewater treatment from heavy metal ions, including sorbent treatment, by settling for 3 hours in the presence of finished gypsum products with dimensions 20 × 20 × 20 mm obtained by mixing gypsum powder distilled water, with the addition of sodium carbonate Na 2 CO 3 in the ratio of 15% by weight of gypsum.
ПРИМЕР КОНКРЕТНОГО ВЫПОЛНЕНИЯ.EXAMPLE OF SPECIFIC IMPLEMENTATION.
Предлагаемый способ осуществляется следующим образом. В качестве фильтрующего материала используют готовые изделия из гипса, которые получают следующим образом: в однородное гипсовое молочко, полученное при затворении порошкообразного гипса CaSO4⋅0,5H2O дистиллированной водой, замешиваются кристаллы карбоната натрия Na2CO3 в соотношении 15% от массы CaSO4⋅0,5H2O. Гипсовое молочко разливается в формы с кубическими ячейками размерами 20×20×20 мм. Результатом схватывания гипсового молочка являются гипсовые изделия.The proposed method is as follows. Ready-made gypsum products are used as the filtering material, which are prepared as follows: in a homogeneous gypsum milk obtained by mixing powdered gypsum CaSO 4 ⋅0.5H 2 O with distilled water, crystals of sodium carbonate Na 2 CO 3 are mixed in a ratio of 15% by weight CaSO 4 ⋅0.5H 2 O. Gypsum milk is poured into molds with cubic cells measuring 20 × 20 × 20 mm. The setting of gypsum milk results in gypsum products.
Очистке подвергались сточные воды, содержащие ионы тяжелых металлов. Отбор проб проводился после 3-х часов контакта сорбента со сточной водой. Определялась концентрация ионов меди, свинца и кадмия. Контроль за степенью очистки воды от ионов тяжелых металлов проводился на атомно-абсорбционном спектрометре.Wastewater containing heavy metal ions was treated. Sampling was carried out after 3 hours of contact of the sorbent with wastewater. The concentration of copper, lead and cadmium ions was determined. The degree of purification of water from heavy metal ions was monitored using an atomic absorption spectrometer.
В таблице приведены полученные результаты по качеству очистки сточных вод.The table shows the results obtained on the quality of wastewater treatment.
