(Б ) СПОСОБ ОЧИСТКИ СТОЧНЫХ ВОД ОТ СЕРОСОДЕРЖАЩИХ СОЕДИНЕНИЙ(B) METHOD FOR CLEANING WASTE WATER FROM SEROMIC CONTAINING COMPOUNDS
Изобретение относитс к способу очистки сточных вод от серосодержащих соединений и может быть использовано дл очистки стоков целлюлознобумажной промышленности.The invention relates to a method for treating wastewater from sulfur-containing compounds and can be used to clean the wastewaters of the pulp and paper industry.
Известен способ очистки сточных вод от серосодержащих соединений путем контактировани с сорбентом полимерным хиноном lj.A known method of purification of wastewater from sulfur-containing compounds by contact with the sorbent polymer quinone lj.
Недостатком способа вл етс невысока степень очистки .сточных вод от серосодержащих соединений.The disadvantage of this method is the low degree of purification of wastewater from sulfur-containing compounds.
Цель изобретени - повышение степени очистки сточных вод от серосодержащих соединений.The purpose of the invention is to increase the degree of purification of wastewater from sulfur-containing compounds.
Поставленна цель достигаетс тем, что согласно способу очистки сточных вод от серосодержащ.их соединений пу- тем контактировани сточных вод с сорбентом-галогензамещенным полимерным хиноном, в качестве сорбента используют галогензамещенный полимерный хинон.The goal is achieved by the fact that according to the method of wastewater purification from sulfur-containing compounds by contacting the wastewater with a sorbent-halogen-substituted polymer quinone, a halogen-substituted polymer quinone is used as a sorbent.
Пример. КЮОмг хлорзамещенного полимерного хинона с электроннообменной емкостью (ЗОЕ) 1,38 мг-экв/г добавл ют 5 мл раствора с рН 7,2, содержащего SH-групп (дисульфидные св зи предварительно восстанавливают насыщенным раствором сульфита натри ). Затем смесь встр хивают . Через определенные промежутки Времени отбирают пробы и определ ют в них количество SH-групп амперометрически с азотнокислым серебром. Убыль SH-группы при 15-минутном контакте 98,1%.Example. CUOMy of a chlorine-substituted polymer quinone with an electron exchange capacity (EOE) of 1.38 mEq / g is added 5 ml of a solution with a pH of 7.2 containing SH-groups (disulfide bonds are pre-reduced with a saturated solution of sodium sulfite). The mixture is then shaken. After certain intervals of time, samples are taken and the number of SH-groups is determined in them amperometrically with silver nitrate. The decrease in SH-group with a 15-minute contact of 98.1%.
Пример 2.К100мг бромзамещенного полимерного хинона с ЭОЕ-13 2 мг-экв/г добавл ют 5 мл раствора с рН 7,2, содержащего 10 М SH-групп. Далее как в примере 1. Убыль SH-групп при 15-минутном контакте 98,7%.Example 2. K100mg of bromo-substituted polymeric quinone with EOE-13 2 mg-eq / g was added 5 ml of a solution with a pH of 7.2 containing 10 M SH-groups. Further, as in Example 1. A decrease in SH-groups at a 15-minute contact is 98.7%.
Пример 3. КЮОмг иодзамещенного полимерного хинона с ЗОЕ Example 3. KUOMog iodosubstituted polymer quinone with OOE

11,8 мг-экв/г добавл ют 5 мл раст- Сравнительные данные по убыли вора рН 7,2, содержащего 10 М SH-rpynn при очистке сточных вод изSH-групп . Далее как в при мере 1 .Убыль вестным и предлагаемым способом приSH-rpynn при 15-минутном контакте 95,91. ведены в таблице. 11.8 mEq / g was added 5 ml of plant. Comparative data on the loss of a thief of pH 7.2, containing 10 M SH-rpynn in wastewater treatment from SH groups. Then, as in measure 1. It was known and proposed by the method at SH-rpynn at a 15-minute contact 95.91. listed in the table.
Предлагаемый по примеруSuggested by example
Как видно из приведенной таблицы, предлагаемый способ позвол ет значительно повысить степень очистки сточных вод от серосодержащих соединений и может быть эффективно использован дл очистки стоков целлюлозно-бумажной промышленности.As can be seen from the table above, the proposed method can significantly increase the degree of purification of wastewater from sulfur-containing compounds and can be effectively used to clean the wastewater of the pulp and paper industry.
