Description
(54) СПОСОБ ОЧИСТКИ КИСЛЫХ РАСТВОРОВ(54) METHOD FOR CLEANING ACID SOLUTIONS
осадок гидрата закиси отдел ют от раствора роданистого натри фильтрованием. Раствор роданистого натри направл ют на использование в основной технологический процесс, а осадок гидрата закиси меди обрабатывают 40-50 мл очищенных сточных вод, содержащих 54 мг/л серной кислоты, и возвращают на очистку сточных вод.the precipitate of nitrous hydrate is separated from the solution of sodium roganide by filtration. Rodanate sodium solution is sent for use in the main process, and the precipitate of copper oxide hydrate is treated with 40-50 ml of purified wastewater containing 54 mg / l of sulfuric acid, and returned to wastewater treatment.
Пример 2. Процесс осуществл ют аналогично примеру 1 с обработкой фильтрата, образзющегос после отделени осадка роданида меди овоном при содержании в растворе серной кислоты - 75 г/л в течение 2 ч.Example 2. The process is carried out analogously to example 1 with the treatment of the filtrate formed after the separation of copper rhodanide by ovons when the content in sulfuric acid solution is 75 g / l for 2 hours.
Предложенный способ по сравнению с известным обеспечивает повыщение степени очистки от роданидов до 89% (в1место 62%); от йтаконовой кислоты до 100% (вместо 58%) и снижение химического потреблени кислорода до 85 мг/л. Сброс токсичных отходов в канализацию и отвалы полностью исключаютс .The proposed method, in comparison with the known, provides an increase in the degree of purification from rhodanides up to 89% (instead of 62%); from itaconic acid to 100% (instead of 58%) and reduction of chemical oxygen consumption to 85 mg / l. Discharge of toxic waste into sewers and dumps is completely excluded.
Предложенный способ обеспечивает снижение стоимости готовой продукции на 7-10%.The proposed method reduces the cost of the finished product by 7-10%.
