(54) СПОСОБ ОЧИСТКИ ОТ АКТИВНОГО(54) METHOD FOR CLEANING FROM ACTIVE

--I--I

СТОЧНЫХ ВОД WASTEWATER

В П J в ХЛОРАIN P J IN CHLORA

водным раствором формальдегида концентрацией 36 вес.%.an aqueous solution of formaldehyde concentration of 36 wt.%.

Содержаниегипохлоритов в раствор через 10 мин равн лось 0,63 г/л; через 20 мин - О, через 30 мин - 0,63 г/л.The content of hypochlorites in the solution after 10 minutes was equal to 0.63 g / l; after 20 minutes - O, after 30 minutes - 0.63 g / l.

Степень обезвреживани  - 99,2%.The degree of neutralization is 99.2%.

Пример 2. Провод т обработку 200 мл раствора,имеющего состав , как в примере 1, врдным раствором формальдегида, концентрацией 18 вес.%.Example 2. 200 ml of a solution having a composition as in Example 1 is treated with a solid formaldehyde solution at a concentration of 18% by weight.

Содержание гипохлоритов в растворе через, 10 мин равн лось 0,89 г/л; через 20 мин - 0,71 г/л; через 30 мин - 0,63 г/л.The content of hypochlorites in the solution after 10 minutes was equal to 0.89 g / l; after 20 minutes - 0.71 g / l; after 30 minutes - 0.63 g / l.

Степень обезвреживани  - 99,2%.The degree of neutralization is 99.2%.

Пример 3.Провод т обработку 200 мл раствора, имеющего состав, как в примере 1, водным раствором формальдегида, концентрацией 9 вес.%.Example 3. A treatment with 200 ml of a solution having a composition as in Example 1 with a formaldehyde aqueous solution at a concentration of 9% by weight was carried out.

Содержание гипохлоритов в растворе через 10 мин равн лось 1,75 г/л; через 20 мин - 1,06 г/л; через 30 мин - 0,63 г/л.The content of hypochlorites in the solution after 10 min was 1.75 g / l; after 20 min - 1.06 g / l; after 30 minutes - 0.63 g / l.

Степень обезвреживани - 99,2 %.The degree of neutralization is 99.2%.

Предлагаемый способ прост в осуществлении , требует меньшего количества восстановителей, сокращает образование карбонатов и позвол ет сократить врем  обработки до 10 мин.The proposed method is simple to implement, requires fewer reducing agents, reduces the formation of carbonates, and reduces the processing time to 10 minutes.
