Изобретение относитс к способам очистки сточных вод от перекиси водорода и может быть использовано в химической промышленности .This invention relates to methods for treating wastewater from hydrogen peroxide and can be used in the chemical industry.
Известен способ очистки сточных вод от перекиси водорода обработкой озоном в щелочной среде при .A known method of purification of wastewater from hydrogen peroxide treatment with ozone in an alkaline medium at.
С целью упрощени процесса очистки сточных вод от перекиси водорода в сточные воды ввод т эквимолекул рное количество гинохлорита натри при рН 7,5-13,5.In order to simplify the process of purifying wastewater from hydrogen peroxide, an equimolecular amount of sodium hydrochloride at pH 7.5-13.5 is introduced into the wastewater.
Гипохлорит натри , вступа в реакцию с перекисью водорода, разлагает его. При этом протекает реакци Sodium hypochlorite, reacting with hydrogen peroxide, decomposes it. In this case, the reaction proceeds.
NaCIO + NaCl + + ОNaCIO + NaCl + + O
При введении стехиометрического количества гипохлорита натри происходит полное разложение перекиси водорода в щелочнойWith the introduction of the stoichiometric amount of sodium hypochlorite, complete decomposition of hydrogen peroxide occurs in alkaline
среде при рН 7,5-13,5. При этом не образуетс побочных вредных веществ, требующих дополнительной очистки.medium at pH 7.5-13.5. In this case, no adverse substances that require additional purification are formed.
Пример. Сточную воду, содержащую перекись водорода в количестве 0,1 -1,0 вес. %, перемещивают с эквимолекул рным количеством гипохлорита натри в виде водного раствора 10-12%-ной концентрации в щелочной среде при 15-20°С.Example. Sewage water containing hydrogen peroxide in an amount of 0.1 -1.0 weight. %, transferred with an equimolar amount of sodium hypochlorite in the form of an aqueous solution of 10–12% concentration in an alkaline medium at 15–20 ° C.
В обработанной сточной воде перекись водорода полностью отсутствует.Hydrogen peroxide is completely absent in treated wastewater.
Предмет изобретени Subject invention
Способ очистки сточных вод от перекиси водорода химическим разложением, отличающийс тем, что, с целью упрощени процесса, в сточную воду ввод т эквимолекул рное количество гипохлорита натри при рН 7,5-13,5.A method of purifying wastewater from hydrogen peroxide by chemical decomposition, characterized in that, in order to simplify the process, an equimolecular amount of sodium hypochlorite is introduced into the wastewater at a pH of 7.5-13.5.
