Description

(54) СПОСОБ РЕГЕНЕРАЦИИ АКТИВИРОВАННОГО УГЛЯ(54) METHOD FOR ACTIVATED CARBON REGENERATION

ВНОВЬ включают в технологическую схему очистки воды. Промывочный pacTBOi может использоватьс  многократно .AGAIN include in the technological scheme of water purification. Wash pacTBOi can be used repeatedly.

Пример, Проводитс  регенераци  отработанного гранулированного активированного угл  в адсорбере с подачей озоно-воздушной смеси с концентрацией озона в пределах : 11,8-31,8 г/м и промывочного раствора, имеющего рН в пределах 7,4-14. Продолжительность регенерации составл ет 6 ч. Результаты опытов в сравнении с аналогичными результатами осуществлени  известного способа приведены в таблице.Example: Waste granulated activated carbon is regenerated in an adsorber with an ozone-air mixture supplied with an ozone concentration in the range: 11.8-31.8 g / m and a washing solution having a pH in the range 7.4-14. The duration of regeneration is 6 hours. The results of the experiments in comparison with the similar results of the implementation of the known method are shown in the table.

Из таблицы следует, что применение предлагаемого способа позвол ет в 3-4 раза снизить удельный расход 5 озона,а следовательно,и всей озоновоздушной смеси на l г адсорбированных органических примесей, а также на 13-34% повысить степень регенерации с известным способом. Из приведенных данных следует, что оптималь0 ными услови ми осуществлени  способа  вл ютс  рН проилвочного раствора 12-13 и применение противоточной циркул ции раствора.It follows from the table that the application of the proposed method allows a 3-4 times reduction in the specific consumption of ozone 5 and, consequently, the whole ozone-air mixture per lg of adsorbed organic impurities, as well as a 13-34% increase in the degree of regeneration with a known method. From the above data, it follows that the optimal conditions for the implementation of the method are pH of the production solution 12–13 and the use of countercurrent circulation of the solution.
