Description
(54) СПОСОБ ОЧИСТКИ СТОЧНЫХ ВОД ОТ ФЕНОЛОВ(54) METHOD FOR CLEANING WASTE WATER FROM PHENOLS
раздела рафинатного и экстрактного растворов благодар чему, улучшаетс расслаивание фаз, увеличиваетс удельна производительность экстракторов и упрощаетс процесс экстракции ,section of the raffinate and extract solutions, thereby improving the separation of the phases, increasing the specific capacity of the extractors and simplifying the extraction process,
Извлечение сульфонов из обесфеноле ной воды осуществл ют многократной протйвоточной реэкстоакцией тем же углеводородом. Регенерацию сульфонов и углеводородов из экстрактных рас-гворов ведут путем дистилл ции, при этом из смеси растворов отдельными погонами получайт углеводород и фенолы. Полученный углеводород смешивают с сульфонами (кубовый остаток ) и подают на экстракцию фенолов из сточной воды.The extraction of sulfones from the dephenolized water is carried out by repeated anti-spinning with the same hydrocarbon. The regeneration of sulfones and hydrocarbons from the extracts of the extracts is carried out by distillation, with hydrocarbons and phenols being obtained from a mixture of solutions in separate strands. The resulting hydrocarbon is mixed with sulfones (bottoms) and fed to the extraction of phenols from wastewater.
Пример. Сточную воду после карбонизации,содержащую 8,26 г/л фенолов,, в количестве 100 мл подвергают очистке методом противоточной экстракции в сис/теме стекл нных смесителей-отстойников при следующих услови х-:Example. After carbonization, waste water containing 8.26 g / l of phenols, in an amount of 100 ml, is subjected to purification using countercurrent extraction in a system / topic of glass mixer-sumps under the following conditions:
Температура, °С 20-30 Число ступеней 3Temperature, ° C 20-30 Number of stages 3
Соотношение водасульфоны-бензин 10:1:1The ratio of water sulfone-gasoline 10: 1: 1
Врем перемешивани Mixing time
в каждой ступени,мин 10in each step, min 10
Врем отсто в каждой ступени,мин5Time for each stage, min5
Содержание фенолов в очищенной воде составило 0,03 г/л, степень обесфеноливани - 99,7%..The content of phenols in purified water was 0.03 g / l, the degree of dephenolization - 99.7% ..
Пример 2. Процесс обесфеноливани провод т аналогично примеру I, но при соотношении вода-сульфон-бензол - 40:2 и времени отсто в каждой ступени 10 мин. Содержание фенолов в очищенной воде, составило 0,066 г/л, степень обесфеноливани - 99,2%.Example 2. The process of dephenolization is carried out analogously to example I, but with a water-sulfon-benzene ratio of 40: 2 and a residence time in each step of 10 minutes. The content of phenols in purified water was 0.066 g / l, the degree of dephenolization - 99.2%.
Таким образом, использование предлагаемого способа очистки сточных вод от фенолов, по сравнению с известными,позвол ет упростить процесс за счет аппаратурного оформлени и повысить производительность процесса за счет уменьшени в зкост экстрактного раствора.Thus, the use of the proposed method of purification of wastewater from phenols, in comparison with the known ones, makes it possible to simplify the process by instrumentation and to increase the productivity of the process by reducing the viscosity of the extract solution.
