Abstract
Способ обработки оборотной воды, включающий обработку воды ультрафильтрацией, сорбцией, обратным осмосом, отличающийся тем, что проводят постадийную очистку оборотной воды от примесей, включающую химическую очистку от примесей, фильтрование, сорбцию золота на смоле, озонирование, ультрафильтрацию и обратный осмос, причем химическую очистку воды проводят перкарбонатом натрия, при расходе последнего не менее 0,25 кг/м3, при перемешивании в течение не менее 15 мин, далее воду фильтруют, для удаления образующегося осадка, полученный фильтрат направляют на сорбционную очистку на смоле для извлечение золота, с регулированием скорости протока не менее 10 м3/м2ч·мм, полученный концентрат выводят из процесса, а воду после сорбции золота направляют на озонирование, с расходом озона не менее 20 г/м3·ч и разложением роданидов в течение 15-20 мин, обезвреженная от роданидов, содержащая осадок вода подается на стадию ультрафильтрации, для предварительной очистки от твердых примесей, под давлением в аппарате 7-9 атм и рН 5-7, полученный концентрат возвращают на стадию фильтрации, а очищенная вода поступает на стадию обратного осмоса при давлении в аппарате 8-12 атм, полученный после стадии обратного осмоса концентрат, не более 10-15% от объема переработки, сбрасывают в хвостохранилище, а полученную очищенную воду - в природный водоем. A method for treating recycled water, including treating water with ultrafiltration, sorption, reverse osmosis, characterized in that stepwise purification of the reverse water from impurities is carried out, including chemical purification of impurities, filtering, sorption of gold on a resin, ozonation, ultrafiltration and reverse osmosis, and chemical cleaning water is carried out with sodium percarbonate, at a flow rate of at least 0.25 kg / m3, with stirring for at least 15 minutes, then the water is filtered, to remove the precipitate formed, the filtrate obtained they are sent for sorption purification on a resin to extract gold, with a flow rate of at least 10 m3 / m2h · mm, the concentrate obtained is removed from the process, and water after sorption of gold is sent to ozonation, with an ozone flow rate of at least 20 g / m3 · h and decomposition of rhodanides for 15-20 minutes, decontaminated from rhodanides, water containing sediment is fed to the ultrafiltration stage, for preliminary purification from solid impurities, under pressure in the apparatus of 7-9 atm and pH 5-7, the resulting concentrate is returned to the filtration stage, and purified water stumbles on the reverse osmosis step under a pressure of 8-12 atm in the device obtained after the reverse osmosis stage of the concentrate, not more than 10-15% of the processing volume is dropped into tailings, and the resulting purified water - a natural pond.
