Изобретение относитс к очистке сточных вод производства перекиси водорода.This invention relates to the treatment of wastewater from the production of hydrogen peroxide.
Известен способ разложени перекиси в водных растворах в щелочной среде при рН 12 и температуре 80°С в присутствии катализатора .A known method for the decomposition of peroxide in aqueous solutions in an alkaline medium at pH 12 and a temperature of 80 ° C in the presence of a catalyst.
Цель изобретени - полное разложение перекиси водорода.The purpose of the invention is the complete decomposition of hydrogen peroxide.
Эта цель достигаетс тем, что раствор выдерживают 1-3 час при 75-97°С.This goal is achieved by maintaining the solution for 1-3 hours at 75-97 ° C.
Это обеспечивает полное разложение перекиси водорода (до следов) в водных растворах без введени специальных катализаторов, которые загр зн ют очищаемую воду.This ensures the complete decomposition of hydrogen peroxide (to traces) in aqueous solutions without introducing special catalysts that contaminate the water to be purified.
Пример. Сточные воды, содержащие (в вес. %): 2 перекиси водорода, 5 изопропилового спирта и 14 ацетона, подвергают сначалаExample. Wastewater containing (in wt.%): 2 hydrogen peroxide, 5 isopropyl alcohol and 14 acetone, is first subjected
отгонке от органических веществ ректификацией при атмосферном давлении. Водный раствор (кубовый остаток) подщелачивают едким натром до рН 13,5, нагревают до 97°С и выдерживают 2 час при указанной температуре .distillation from organic matter by distillation at atmospheric pressure. The aqueous solution (vat residue) is alkalinized with caustic soda to a pH of 13.5, heated to 97 ° C and kept for 2 hours at the indicated temperature.
После такой обработки водный раствор содержит следы перекиси водорода.After this treatment, the aqueous solution contains traces of hydrogen peroxide.
Предмет изобретени Subject invention
Способ разложени перекиси водорода в водных растворах при рН 12-14 и температуре 75-97°С, отличающийс тем, что, с целью полного разложени перекиси водорода , раствор выдерживают 1-3 час при указанной температуре.The method of decomposition of hydrogen peroxide in aqueous solutions at pH 12-14 and a temperature of 75-97 ° C, characterized in that, in order to completely decompose hydrogen peroxide, the solution is kept for 1-3 hours at the specified temperature.
