Abstract
Изобретение .относитс к способам очистки сточных вод от органических примесей, может использоватьс в химической, нефтехимической и других отрасл х промьшшенности и позвол ет повысить степень очистки и сократить врем процесса. Сточные воды очищают от бензола путем десорбции в токе воздуха, содержащего пары метанола или этанола, или пропанола. 1 табл.The invention relates to methods for purifying wastewater from organic impurities, can be used in the chemical, petrochemical, and other industrial sectors and allows an increase in the degree of purification and shorten the process time. Wastewater is purified from benzene by desorption in a stream of air containing methanol or ethanol or propanol vapors. 1 tab.
Description
Изобретение относитс к способам очистки, сточных вод от органических примесей и может быть использовано в химической, нефтехимической и дру- гих отрасл х промышленности.The invention relates to methods of treating wastewater from organic impurities and can be used in the chemical, petrochemical and other industries.
Целью изобретени вл етс повышение степени очистки и сокращение времени процесса.The aim of the invention is to increase the degree of purification and reduce the process time.
Пример 1, В цилиндрический сосуд, дном которого служит пориста перегородка, помещают 1 л сточной воды с содержанием бензола 820 мг. Десорбцию б ензола ведут воздухом, подат ваемым со скоростью 200 мл/мин. Пос- ле 20 мин продувки воздухом сточную воду анализируют на содержание бензола .Example 1 In a cylindrical vessel, the bottom of which is a porous septum, placed 1 liter of waste water with benzene content of 820 mg. Desorption of a benzene is carried out with air fed at a rate of 200 ml / min. After 20 minutes of purging with air, the wastewater is analyzed for benzene content.
Пример 2, Б цилиндрический сосуд, дном которого служит пориста перегородка, помещают 1 л сточной воды с содержанием бензола 820 мг. Десорбцию бензола ведут воздухом, подаваемым в количестве 200 мл/мин иExample 2, B a cylindrical vessel, the bottom of which is a porous septum, is placed 1 liter of waste water with benzene content of 820 mg. Desorption of benzene is carried out with air supplied in the amount of 200 ml / min and

содержащим различные количества паров метанола, этанола или пропанола. После 5 мин продувки сточную воду анализируют на содержание бензола..containing various amounts of methanol, ethanol or propanol vapor. After 5 minutes of purging, the waste water is analyzed for benzene content ..
Данные по количеству спиртов, содержащихс в воздухе, и результаты опытов представлены в таблице„Data on the amount of alcohols contained in the air, and the results of the experiments are presented in the table „
Как следует из представленных в таблице данных, ведение.процесса десорбции бензола воздухом, содержащим пары спиртов, приводит к повьшению степени очистки сточных вод и сокращению времени процесса.As follows from the data presented in the table, the maintenance of the process of desorption of benzene with air containing vapors of alcohol leads to an increase in the degree of wastewater treatment and a reduction in the process time.
