Изобретение относитс к химической технологии, а именно к ионообменным адсорбционным процессам очистки растворов , и может быть использовано при очистке сточных, шахтных вод и растворов от содержащегос в них фтора.The invention relates to chemical technology, in particular to ion-exchange adsorption processes for the purification of solutions, and can be used in the purification of wastewater, mine water and solutions from fluorine contained in them.
Цель изобретени - снижение продолжительности процесса очистки сточных вод от фтора.The purpose of the invention is to reduce the duration of the wastewater treatment process from fluorine.
Способ очистки сточных вод, содержащих фтор, включает обработку известковым молоком, сорбцию фтор-ионов из образующейс пульпы путем пропускани через слой пористого анионита в смешанной ОНГ -§10з2 -форме, последующую нейтрализа- цйю очищенных стоков.The method of purification of waste water containing fluorine includes the treatment with lime milk, the sorption of fluorine ions from the resulting pulp by passing through a layer of porous anion exchanger in mixed ONG -§1032-form, followed by neutralization of the treated effluent.
Способ очистки сточных вод от фтора состоит в следующем.The method of purification of wastewater from fluorine is as follows.
Шахтные воды с известным химическим составом на первой стадии обрабатывают 10%-ным раствором Са(ОН)2 в течение 15Mine water with a known chemical composition in the first stage is treated with a 10% solution of Ca (OH) 2 for 15
мин при перемешивании. Затем на второй стадии полученную пульпу профильтровывают через слой анионита в смешанной ОН- 5Юз2 форме, после чего анализируют фильтрат.min with stirring. Then, in the second stage, the resulting pulp is filtered through anion exchanger in a mixed OH-5Uz2 form, and then the filtrate is analyzed.
П р и м е р 1. Заданный обьем шахтной воды с химическим составом, указанным в табл. 1, обработан по прототипу сначала 10%-ным раствором Са(ОН)2 с расходом 130 мл/л по активной СаО в течение 15 мин при перемешивании, затем полученную пульпу отстаивали в течение 2 ч. Осадок (50 мл/л) выбрасывали, остальную фазу обрабатывали в течение 15 мин раствором активной кремнекислоты с расходом 1,5 мл 5%-ного жидкого стекла на 1 л шахтной воды, при перемешивании отстаиваивали в течение 2 ч, осадок фторсиликатов (20 мл/л) выбрасывали , жидкую фазу обрабатывали 10%-ным раствором Са(ОН)2 в течение 15 мин с расходом 75 мг СаО на 1 л шахтной воды, отстаOsPRI me R 1. Given the volume of mine water with the chemical composition indicated in the table. 1, treated with the prototype, first with a 10% solution of Ca (OH) 2 with a flow rate of 130 ml / l of active CaO for 15 minutes with stirring, then the resulting pulp was settled for 2 hours. The precipitate (50 ml / l) was thrown out the remaining phase was treated for 15 minutes with a solution of active silica with a flow rate of 1.5 ml of 5% liquid glass per 1 liter of mine water, with stirring, settled for 2 hours, the precipitate of fluorosilicates (20 ml / l) was thrown away, the liquid phase was treated with 10 % solution of Ca (OH) 2 for 15 minutes at a rate of 75 mg CaO per 1 liter of mine water, settles

ивали в течение 2 ч, осадок (20 мл/л) выбрасывали , а осветленную фазу анализировали.The mixture was heated for 2 hours, the precipitate (20 ml / l) was discarded, and the clarified phase was analyzed.
П р и м е р 2. Шахтную воду того же состава (см. табл. 1) и в том же объеме обрабатывали 10%-ным раствором Са(ОН)2 с расходом 130 мл/л в течение 15 мин при перемешивании. На второй стадии пульпу профильтровывали через слой анионита ВП-1Ап в смешанной ОН -8Юз2 форме со скоростью 21 объем/объем смолы в 1 ч. Фильтрат подвергали анализу. Суммарное врем одного цикла составило 1 ч 15 мин.PRI mme R 2. Mine water of the same composition (see Table 1) and in the same volume was treated with 10% Ca (OH) 2 solution with a flow rate of 130 ml / l for 15 minutes with stirring. In the second stage, the pulp was filtered through a layer of VP-1An anion exchanger in a mixed OH-8U2 form at a rate of 21 volume / volume of resin per 1 hour. The filtrate was analyzed. The total time of one cycle was 1 h 15 min.
Показатели обоих процессов приведены в табл.2.The indicators of both processes are given in table 2.
При использовании предлагаемого способа очистки сточных вод от фтора значительно сокращаетс врем , в течение которого происходит очистка стоков, что позвол ет увеличить количество очищаемой воды. When using the proposed method of treating wastewater from fluorine, the time during which wastewater treatment takes place is significantly reduced, which allows an increase in the amount of water to be purified.
